TEELEN TL-2900A Binocular Transmission Polarizing Microscope Picture

Instrument Introduction

Polarizing microscopes use the principle that light will produce polarized light through reflection, refraction, birefringence or scattering under certain conditions. Two polarizing filters that rotate with each other are added to the optical instrument to obtain a comfortable light intensity and improve the object. Contrast with the background.

Features

▲ Adopt infinity optical system and modular function design.

▲ Equipped with a stress-free long working distance plan objective.

▲ Wide-angle flat-field eyepiece: field of view diameter Ф18mm.

▲ Coarse and fine motion coaxial focusing mechanism, coarse motion adjustable, with limit locking device, fine motion scale value: 2μm.

▲ The polarized light observation device can be moved in or out of the optical path, and the polarizer and analyzer can be rotated 360°.

▲ Rotary stage, 360° equal division scale, vernier grid value 6', center adjustable, with locking device, the effective vertical stroke of the table can reach 35mm.

▲ Wide Voltage power supply (220V 50/60Hz). 6V20W halogen lighting with adjustable brightness.

▲ The trinocular tube can freely switch between visual observation and microphotography, and can be 100% light-transmitting during photography, which is suitable for low-light microscopic image shooting.
