MODE D'EMPLOI TL-BASES LEICA
Observe and Document in the Best Light
Leica's new stereomicroscope stands bring light into sophisticated observation and research
The Quality of Light Used…
...plays a basic role in microscopic analyses. The quality of any optical system is only as good as the light available. With a new family of specialized stereomicroscope stands, Leica continues to offer top performance, consistent modularity, and ergonomy. Leica stereomicroscopes are known worldwide for exceptional optical performance. The Leica MZ16 stereomicroscope with 16 × magnification particularly benefits from these new stands. Leica's new TL ST transmitted light stand, TL BFDF bright-
field/darkfield stand, and the high-performance TL RC ^TM and TL RCI ^TM stands offer the right solution for every task, space requirement, and budget. Leica's incident light stand sets new design standards for weight-bearing sturdiness, without compromising ergonomics or its vibration-dissipation ability.

Leica TL ST
Transmitted Light Stand
Control the brightness of the light source and the mirror between the two guided end positions.
The halogen lamp can be replaced quickly and easily.
Variable light guide provides full control
Operating the Leica TL ST transmitted light stand is easy. Simply set the brightness with a potentiometer. The mirror, which guides light through the specimen at different angles, can glide across the horizontal plane. The tilt angle of the mirror is then automatically aligned. In this way the user has full control of the transmitted light without having to spend time looking for the best transmitted light angle.
Leica's new halogen lamp is particularly efficient. With a capacity of only 20W, it reaches the light utilization of a 35W lamp. The heating effect is noticeably reduced, and temperature-sensitive specimens especially benefit from the lower wattage.
Daylight filter reproduces natural color-tone
Leica offers a daylight filter accessory for the standard transmitted light stand. The highly-coated glass raises the color temperature and cuts off the infrared and UV spectrum of the halogen lamp. This provides a spectrum similar to daylight.
Change the lamps in a matter of seconds
The new, easy-to-use lamp changing mechanism enables quick replacement of a halogen lamp. After a cooling down phase, the user can access the lamp holder directly by removing two screws on the heat sink.
Work in comfort
The large work surface of the standard transmitted light stand enables comparative analysis of several specimens. While a specimen is analyzed under the stereomicroscope, the other specimens can remain on the stand for quick changeover if need be. A large glass plate protects the stand from any fluids should a spill occur.

Leica TL BFDF
Transmitted Light Stand
Continuously adjustable changeover between brightfield and darkfield
Leica's direct, transmitted light brightfield is available for studying stained amplitude specimens with sufficient contrast. The new, high-performance TL BFDF transmitted light stand offers versatile options. Light rays can be deflected through the specimen from steep to flat, and a high or low degree of diffusion can be selected. For example, if the light rays are deflected absolutely vertically through the specimen, an exact brightfield with maximum brightness is created. The specimen appears with full contrast, in natural color on a bright, homogenous background.
If the light is deflected through the specimen at an oblique angle, however, this makes it easier to view semi-transparent specimens such as foraminifera and fish eggs. The flatter the light rays are deflected into the specimens, the darker the background appears. Contours, fine
edges, and structures are brightly and clearly emphasized by diffraction of the light on a dark background.
SlideOn™ design provides easy stage changeover
When purchasing a new Leica stereomicroscope stand, if the standard stage is ordered instead of the new XY stage, the standard stage (with Leica's patented SlideOn™ design) can be quickly replaced by the new XY stage (see p. 9).
Effective vibration dissipation
The vibration-dissipating feet featured on the TL BFDF minimize disturbances during delicate work. External vibrations that influence the stand (impact sound, fan for external light sources, etc.), and any direct disturbances on the stand itself are better dampened than with conventional stand feet.

Contrast method for clear, transparent specimens
Rottermann Contrast™ is a partial illumination technique that shows changes of the refractive index as differences in brightness. Phase structures then typically appear as spatial, relief-type images – like hills in positive relief contrast and as indentations in inverted relief contrast. The two integrated diaphragms that create the relief effect can be individually positioned from fully open to fully closed. The relief effect can also be regulated from slight to strong by precisely tilting the path-folding mirror with the rotary button on the left side of the stand. This technique offers many variable views for extracting the maximum possible amount of information from every specimen.
Perfect coordination with automated stereomicroscopes
Leica's TL RCI^TM transmitted light stand feature two USB ports and two CAN bus interfaces. The brightness of the light source can be controlled via a USB mouse. Combined with motorized Leica stereomicroscopes and macroscopes, motorized focus, and Leica Application Suite (LAS) software, the user has full computer control over the zoom level, focusing, color temperature, brightness, and shutter of the illumination. Many different test series can be extracted from LAS software and automated.
Constant color temperature
Color temperature and brightness are controlled separately with Leica's high-performance stands. Using the CCIC function, the brightness is set completely independently from the color temperature – and the required color impression remains exactly the same when the illumination intensity changes. The potentiometer for the color temperature also has an electronically controlled shutter; if the stand is switched on again after a work break, it automatically returns to the previous settings.
Three available color filter slots
The TL RC™ and TL RCI™ each feature three slots for color filters. These slots can be used for filters that are available as accessories, i.e. neutral gray, fluorescence filter BG38, and UV filter, or fitted with other filters as the user wishes.
Choice of integrated or external light source
The high-performance stands of the TL series are available in two designs: with integrated halogen illumination or with a connection for external cold light sources. If a user already has a cold light source, it can be used on the new stand. In addition, the new Leica CLS150 LS cold light source enables the internal shutter to be controlled directly via a PC.
Totally Integrated Solutions
Leica Application Suite (LAS) integrates Leica's automated microscopes, digital cameras, and software into one common environment to provide an easy-to-use, consistent solution with unrivaled performance. The flexibility of LAS makes it is suitable for a diverse range of life science and industrial applications such as pathology, pharmaceutical testing, materials research, and many others.
LAS solves and accelerates routine and research analysis through rich image processing functions that simplify the visualization, enhancement, measurement, and documentation of digital images. An introductory LAS package is supplied with the latest Leica microscopes and digital cameras which provides the basic software for their configuration and control, and enables the user to immediately begin to acquire, analyze, and process high-quality digital images. These fundamental capabilities can be enhanced with a range of advanced LAS modules and applications to form an integrated microscopy-imaging environment.

Mobility and compact space requirement
Laboratory workstations often provide very little space. Leica's new incident light stands are designed to offer exactly the right amount of surface area. But at the same time, they require a minimum amount of workstation space.
High stability and vibration-dissipation
Leica implemented a honeycomb design structure, which makes the new incident light stands light weight, yet extremely rigid. Despite weighing less than 2kg , the stands are resistant to buckling. The stands also feature specially adapted AntiShock™ vibration-dissipating feet. Compared to conventional pads, the AntiShock feet ensure up to 50% less vibration. The combination of all of these features ensures a steady, excellent quality image during specimen observation and documentation.
Growing for future needs
As science changes, so do the required instruments. When purchasing a microscope system, it is not always possible to know which additional equipment will be needed in the future. Leica's modular design ensures that accessories can be added later, that perfectly adapt to the Leica stereomicroscope system. For example, a variety of focus drives are already available for the new incident light stands.

Precision Guidance of
Incident and Transmitted Light
The axis with the control knobs for X and Y movement of the stage can be mounted either on the left or right of the XY stage.
Precision and speed
With the new Leica XY stage the tedious procedure of manually manipulating the specimen into the correct position under the stereomicroscope is no longer necessary. By means of the two easily moveable, yet extremely precise control wheels, the specimen can quickly be moved after placement until the spot to be investigated is found. By combining the XY stage with the 4 × glass slide, up to four preparations can be placed on the work surface and can be observed vertically in a fast, precise, and easy way. Accuracy is less than 10 m .
Always in focus
Conventional XY stages have the disadvantage of being higher and so do not provide the best level for specimen viewing when transmitted light stands are used. The illuminated area's homogeneity and strength diminish, and light can no longer be well-guided through the specimen. The new Leica XY stage solves this problem. After changing from the standard stage (catalog no. 10447269), the specimen's level remains at exactly the same elevation as before, and the illumination settings remain unchanged.
Leica's SlideOn™ design
Changing over from a standard stage to the XY stage is surprisingly easy. By simply removing several screws, the standard stage can be replaced by the XY stage. If an XY stage is not purchased with a new Leica stereomicroscope stand, the user can easily supplement the instrument at any time in the future.

Perfect Integration
Leica MATS heating stage
The Leica MATS is the most efficient solution for protecting and preserving live cells during microscopic analysis. The low tolerance of 0.2^ between the stage and the specimen enables experiments to be conducted reliably with specimens that require a constant temperature.
4 × glass slide adapter
When combined with the XY stage, this adapter is ideal for comparative analysis of up to four specimens on glass slides.
Live on Stage
Leica's Live on Stage product line (incubation systems, pH-value control, cell cultivation systems, etc.) for Leica's inverted light microscopes enables your stereomicroscope to perform all possible life science tasks, no matter how difficult.
Adapter for 120mm inserts
Leica's adapter for 120mm diameter inserts enables accessories such as a gliding stage, cup stage, and polarization stage to be used (see assembly diagram in the specifications).
Leica ErgoRestTM
The Leica ErgoRestTM armrest enables precise, fatigue-free work at the stereomicroscope. The armrest features two resting levels on the stand to support the arms during focusing or working with a Petri dish.
Footswitch
Leica's new footswitch, controlled by a potentiometer, features a CAN-Bus interface. As a result, the two rockers can be used for any microscope function, such as motorized focus, zoom control, and filter changing (i.e. Leica MZ16 FA).
Leica CLS150 LS cold light source
The CLS150 LS has been specifically adapted to automate control of the new TLRCI™ transmitted light stand via LAS. Through a serial port, the brightness, color temperature, and electronic shutter can be controlled directly from a PC or Leica UMC (manual control).
Micromanipulation
Using Leica's adapter for micromanipulation accessories, applications such as ICSI (Intra Cellular Sperm Injection), transgenic, and electrophysiological experiments are possible for stereomicroscopy.
