Frequently Asked Questions - MED 45B Levenhuk
What is the maximum magnification of the Levenhuk MED 45B?
The maximum magnification is 1600x when using the WF16x eyepiece and the 100x oil immersion objective. With the standard WF10x eyepieces, the maximum is 1000x.
How do I clean the objective lenses?
Use only special lens cleaning paper or a soft lint-free cloth. Moisten with a drop of isopropyl alcohol or lens cleaning solution. Wipe gently in a circular motion. Never use regular paper or cloth as it may scratch the lens.
Can I connect a digital camera to this microscope?
Yes, the Levenhuk MED 45B has a trinocular head with a C-mount adapter (optional) for attaching a microscope camera. This allows you to capture images or videos on a computer.
What type of illumination does the microscope use?
The microscope uses a built-in LED light with adjustable brightness. It can be powered via an AC adapter or its internal rechargeable battery, making it suitable for fieldwork.
How do I adjust the diopter on the eyepieces?
First, focus on a specimen with the left eye using the coarse/fine focus. Then, without touching the focus, look with your right eye and rotate the diopter ring on the right eyepiece until the image is sharp. This compensates for differences in your eyes.
Is oil immersion required for the 100x objective?
Yes, the 100x objective is an oil immersion lens. You must place a drop of immersion oil between the slide and the objective to achieve proper resolution. Do not use oil with any other objective.
What is the warranty period for this microscope?
Levenhuk offers a lifetime warranty on the MED 45B. This covers manufacturing defects but not damage from misuse, normal wear, or accessories. Keep your receipt for service.
Why is the image blurry even after focusing?
Possible causes: dirty lens, incorrect objective alignment, or too thick cover slip. Check that the objective is clicked in place, clean the lenses, and ensure the specimen is properly prepared. Also verify that the condenser is adjusted correctly.
Can I use this microscope for live cell observation?
Yes, the LED illumination produces low heat, making it suitable for live specimens. However, for extended observation, a stage warmer or temperature control may be needed.
Are spare parts available for the Levenhuk MED 45B?
Yes, spare parts such as eyepieces, objectives, bulbs, and stage knobs are available through Levenhuk authorized service centers. Contact your local dealer for ordering.
