OPTICAL MICROSCOPY
Description
The Polyvar Met is a research microscope capable of a wide range of incident and transmitted light techniques.
Optical System
The polyvar optical system produces accurate images of extremely large object fields. The objectives are plan achromates and plan fluorites for infinite tube lengths and have a high brilliance, resolution and flatness of field. Standard, long working distance (LWD) and extra-long working distance (XLWD) objectives are available. With x10 widefield eyepieces the viewing angle is 51°. The range of magnifications available is 16x to 2000x and complies with DIN and ASTM standards.
Illumination System
Illumination is provided by a 100 Watt halogen lamp with a colour temperature of 3200K.
Stage
The stage is stepper motor driven in x and y directions with step size of 0.5µm. The stage travel is 100 x 100mm. The stage can be programmed raster with continuous or step motion.
