Product details

Reflective polarizing microscopeXPV-203

1、 Purpose:
The XPV-203E/XPV-203Z transmission reflection polarizing microscope and melting point determination system are the most commonly used professional experimental instruments in geology, mineral resources, metallurgy, petrochemicals, chemical fiber, semiconductor industry, drug inspection and other departments, as well as in polymer and other related majors in higher education institutions. Reflective polarizing microscope can be used by a wide range of users for single polarization observation, orthogonal polarization observation, cone light observation, and microscopic photography, to observe the deformation, color change, and three state transformation of objects under heating. The reflective polarizing microscope adopts microcomputer detection, with automatic P, I, D adjustment and fuzzy manual adjustment functions. The temperature value and set temperature value are displayed through LED, and the instrument display is accurate, clear, and stable. The temperature control can be programmed, and there is an automatic alarm device for "upper and lower" limits. The set temperature data can be checked at any time. It is a new generation melting point temperature measurement and control device. The microscope is equipped with accessories such as gypsum λ, mica λ/4 test pieces, quartz wedges, and moving rulers. This instrument has scalability and can be connected to computers and digital cameras to edit, save, and print images. It is a new type of product with relatively complete functions.

2、 System Introduction:

The reflective polarizing microscope system is a high-tech product developed by perfectly combining precision optical microscope technology, advanced photoelectric conversion technology, and cutting-edge computer image processing technology. Reflective polarizing microscope can conveniently observe real-time dynamic images on the display screen, and can edit, save, and print the required images.

4、 Reflective lighting, coaxial lighting (also known as vertical lighting)
Coaxial Illuminator, also known as Vertical Illuminator, is a vertical illumination system for microscopes with a system factor of 1. It can be adapted to various models of ordinary (160mm mechanical tube length, oblique tube type) microscopes. It can be used as a reflection light illumination system to observe the subtle structures on the surface of opaque objects.
The vertical lighting device configuration and microscope can not only perform general metallographic analysis and particle analysis testing, but also analyze and observe non-metallic opaque objects. It is equipped with a polarizing system for polarizing observation.
