The optical system of the StereoZoom® line consists of two beam paths converging at 12^ . The objective pairs of each optical path are positioned close together, so the stereomicroscopes are slim in design, especially toward the base. The advantages of this design are the small space requirement for use on bonders and in machine applications, unobstructed access to sample, plenty of space for tools, and a completely clear view of the object field. The Greenough optical system enables the correction of aberrations such as chromasia, image field curvature, and distortion with minimal effort. The StereoZoom® line uses the optimally corrected center of the objective for imaging. The result: superior optical performance; large, level, and undistorted fields of view; and chromatically optimized, high-contrast images.

High-performance LED Illumination

The high-quality Leica LED2000/LED2500 illumination stands are robust and suitable for almost any inspection task.

The Leica LED2000 stand is suitable for all incident light applications and is a cost-effective solution when transmitted light is not required. With five illumination options available, the user can choose exactly where and how much light should be applied to a sample. The options include the use of all seven available LEDs for optimum illumination, 4-point incident light for shadowless illumination, two side LEDs for improved contrast, or one oblique LED if low illumination is required. Each illumination option also features dimmer control so that the brightness levels can be adapted to individual requirements. With the light manager touch panel, each setting can be easily selected and reproduced.

The Leica LED2500 includes both incident and transmitted light capabilities, which can be used together or controlled individually. With a 60 mm active light diameter, the Leica LED2500 is perfect for performing detailed inspections at consistent light levels with a large field of view. The 6500°K color temperature means that samples can be examined with true color reproduction.

Moveable arc illumination

The Leica LED2000/LED2500 provides an adjustable arc illumination, which allows the user to increase the contrast level to meet individual requirements. Arc illumination can be optimized for 1.0×, 1.6×, and 2.0× additional objectives.

Maintenance-free

LEDs have a service life of at least 25,000 hours and maintain a constant color temperature, which makes them preferable to conventional light bulbs. With their heat dissipation, the Leica LED2000/LED2500 bases do not require a fan so light vibrations do not interfere.

Daylight quality

The Leica LED2000 and LED2500 illumination stands use state-of-the-art LED technology that closely resembles the light spectrum of daylight. As a result of pulse width modulation (PWM), color temperature remains constant over the entire dimming range. There is no need to readjust the camera's white balance, which makes the complete system easier to handle.
