POL1800 Polarizing Microscope is utilized polarizing light to observe and research the matter which have double refraction features, enable to observe in single polarizing, orthogonal, conoscope. It can be applied in geology, chemicals, physic and leechdom fields, widely used to observe the crystal of liquid macromolecule polymer, biomedical polymer and liquid crystal. It is the ideal instrument for scientific research and universities teaching demo.

Trinocular, single diopter adjustment, inclined 30°, can be connected to the camera. 10X wide field plan eyepiece, field Φ22mm, can provide expanse and smooth observation space. Another eyepiece is 10X division eyepiece used for proofreading the centre.

The intermediate attachment includes the impellent style of analyer (360° retatable with scale and fine nonius) which can be taken off from the light path and the impellent style of bertrand lens (centeradjustable). It can be added λ compensator, λ/4 compensator or quarts wedge compensator. Strain-free plan achromatic objective (no cover glass) and center adjustable.

Rotund rotatable stage, Φ150mm diameter, 360° graduated (in 1° increments), miniunm, retardation resolution 6’, center adjustable and with tightener.

6V 30W halogen lamp, brightness adjustable. Polarizer, 360° rotatable, having 0, 90, 180, 270 four scale, set under the aperture disphragm, can take down from the optics body.

6V 30W halogen lamp, brightness adjustable. Polarizer, 360° rotatable, analyzer can be ratatable 360° with scale and minium vernier. Integrated field and aperture diaphragm.

By adding the appurtenance such as CCD adapter, digital camera adapter and single-reverse digital camera adapter etc. It can achieve high clear observation mode of camera and vidicon.
