Metserve Optical System

Our 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 System

Illumination is provided by a 100 Watt halogen lamp with a colour temperature of 3200K.

Illumination Modules

The following modules are available:
  • Brightfield
  • Darkfield
  • Polarised light
  • Interference contrast
  • Epi-fluorescence

    Photographic System

    • Polaroid 4" x 5" camera
    • Nikon Coolpix 995 camera
 

Dual Reflex Module

The dual reflex module is an optical beam splitter which can be used for:
