The Polyvar Met is a research microscope capable of a wide range of incident and transmitted light techniques.
|
|
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 magifications available is 16x to 2000x and complies with DIN and ASTM standards.
|
|
Illumination is provided by a 100 Watt halogen lamp with a colour temperature of 3200K.
|
|
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.
