are featured for novel appearance, easy and comfortable operation. They provide large field, long depth of field, distinct image, high resolution and stereo observation. The zoom ratio of 1:6.3 enables a wide range of observation at low to high magnifications (5X-378X) by using auxiliary eyepieces and objective lenses, both general and detail of the object can be observed, which improves observation effect. They have found wide application in electronic industry, mechanical industry, textile industry, geological mine industry, agriculture, forestry, herd, biology and medical field Coaxial Illuminator (i.e. built-in illuminator) uses a coaxial optical path for both illumination and observation. In this way, illumination shadow image caused by the side or transmitted illumination can be avoided, and the distortion of object image caused by illumination be reduced. Color interference can be presented on the vibrating plane of the Polaroid by turning 1/4 wave plate, which provides the possibility of observing anisotropic objects.
