Carl Zeiss Jena GmbH has launched the Axiovert 40 Mat, a microscope enhanced for materials research. A five-position nosepiece permits the use of a full range of standard magnifications (5×, 10×, 20×, 50×, 100×), and the stand version has an optional four-position nosepiece. The three-position reflector slider uses "push and click" modules to simplify conversion to different contrasting techniques. A high-intensity 35-W halogen lamp improves homogeneity of illumination and white impression, provides more light in reserve, and extends service life. Options include a rotary analyzer for reflected-light polarization contrast, a lambda slider for colored polarization contrast, a 90° rotary mechanical stage, improved transmitted-light equipment and a selection of high-performance condensers.
