On the product:
40X-1000X 220B binocular professional microscope supports immersion oil, two-stage mechanical stage and fine focusing.

A model suitable for students and professional use from AMZ Instruments, who specialize in the production of microscopes for children, youth, beginners and professionals.

Binocular stereo microscope, with excellent optical quality, magnification up to x1000 and a designed and innovative look
The 220B is a professional binocular microscope suitable for advanced and professional uses:

The microscope has 4 high-quality achromatic self-lenses, one of which supports the use of immersion oil.

In addition, a two-stage mechanical stage to control the position of the specimen being tested and a fine focusing mechanism for precise focusing at any magnification!
You can rotate the head of the microscope 360 degrees, the eyepieces are placed at an angle of 45 degrees and can be adjusted to a smoking distance between 48-75 mm for maximum ease of use.

4 quality achromatic lenses including a 100XS oil immersion lens and a pair of WF10X wide angle eyepieces
The 220B has 3 quality achromatic metallic prime lenses for lower magnifications: a 4X lens, a 10X lens and a 40XS lens which comes with a spring to keep the lens glass in place when focusing.

In addition, the model comes with a fourth self-achromatic lens: 100X(S, Oil) which comes with a spring to keep the lens glass and is ready for use with immersion oil.

All these together will allow you to enlarge the object under examination to a magnification of X1000 and get a high-quality and efficient result.

The immersion oil breaks the light in the right way which concentrates it and allows it to enter the lens in the right way, which improves sharpness and makes the use of 1000x magnification possible and with a quality result.

In addition, you will receive in the kit a pair of WF10X eyepieces with a wide field of view, so that you can magnify the objects between 40X and 1000X and put more of the sample in the field of view at once.

Focusing system – fine, coarse and two-stage mechanical focus for maximum comfort
On the sides of the microscope you will find the focus knobs that control the focus:

Focus on the object under examination with the focus system: help with the fine focus at the high magnifications where you would have difficulty focusing with the coarse focus wheels.

With the help of the fine focus you can focus accurately and reach maximum sharpness even when the depth of field is low.

In addition to this, in this model you will receive a two-stage mechanical stage measuring 110×120 mm, the stage has movement in 2 axes in a fine direction and a range of movement of 70×30 mm.

The mechanical stage is controlled with rotating handles, as a result you can place the center of interest of the sample comfortably and efficiently in the field of view.

Lighting system – bottom lighting and light center ABBE NA1.25 with filter holder
At the base of the microscope you will find a bottom LED light and a wheel to change the lighting intensity.

Also, above the bottom lighting you will find the light center type ABBE NA1.25.

The focusing lens will allow you to concentrate or disperse the light beam according to your needs and will allow you to control the resulting brightness, contrast and depth of field.

In addition, filters can be connected to it to change and control advanced lighting.
