MICROSTRUCTURES

A catalog titled “Standard-Microstructures” from POG Präzisionsoptik Gera GmbH presents a variety of new products, including crosshair eyepiece graticules and eyepiece micrometer scales that are available in more standard diameters to fit a broader range of standard microscopes. It features stage micrometers made from Ceran and Robax glass ceramics in three versions: 1 mm in 100 divisions, 2 mm in 200 divisions and 70 mm with four divisions, specially designed for stereo-microscopes. The new materials offer high mechanical stability and minimal thermal expansion. Glass scales of 50 and 100 mm also are listed.
