The FL7500W computerized metallographic microscope is a trinocular transflective upright metallographic microscope, which is suitable for microscopic observation of opaque objects or transparent objects. This instrument is equipped with an epi-emission and transmission illumination system, a long-distance plan achromatic objective lens (without a coverslip), a large-field eyepiece and a built-in polarization observation device, which has the characteristics of clear image, good contrast and easy operation, and is a satisfactory instrument for the research of biology, metallurgy, mineralogy, precision engineering, electronics, etc. It is suitable for use in schools, scientific research, factories and other departments.
Observation system
Trinocular observation tube, monocular degree adjustable, lens barrel 30° tilt, can be connected to the camera device.

Mechanical stage
Double-layer mechanical stage, size: 185*140mm, moving range: 75mm*50mm, moderate design concept, users are more convenient and comfortable when operating the stage.

Epi-illumination system
6V20W halogen lamp, brightness adjustable. Built-in field diaphragm, (yellow, green, blue, frosted glass) filter converter, push-pull polarizer.

Transmitted illumination system
Built-in halogen illumination: 6V20W halogen lamp (brightness adjustable) can provide clear and vivid microscopic observation images. With field diaphragm collector, Abbe condenser N.A.1.25, adjustable up and down.
