1、 The purpose of the instrument：

The ZYH-700 high-precision polarized light microscope is the most commonly used professional experimental instrument in geological, mineral, metallurgical and related higher education departments. Used for opaque or semi transparent objects, it can use both transmitted and reflected light simultaneously

2、 Instrument features:

The high-precision partial reflection microscope ZYH-700 is mainly used in geological exploration (regional geological exploration, marine geological exploration, hydrogeological exploration, engineering geological exploration, environmental geological exploration, solid mineral exploration, geochemical exploration). The ZYH-700 polarizing microscope is a very suitable product for users to observe with single polarization, orthogonal polarization, cone light, and microscopic photography. It is equipped with accessories such as gypsum λ, mica λ/4 test pieces, quartz wedges, and moving rulers. It is a new type of product with complete functions and good quality This instrument has scalability and can be connected to computers and digital cameras. Save, edit, and print images. High precision reflective microscope is a high-end reflective microscope classified and graded for geological exploration qualifications.
