GEMMODUL is a series of modular gemological instruments that can be used each by itself or combined in one bench. First developed in 1973 the instruments have continuously been optimized until today to supply everything for the gemmologist's needs.
Gem refractometers for measuring the refractive index of gemstones.
Illuminator bases with monochromatic LED light of 589nm. Compatible with most gem refractometers.
Coldlight gem polariscopes with diffuse white fluorescent light.
Optical Spectroscope System with direct readable scale from 700 - 400 nm.
Coldlight illuminator base 100 Watt for spectroscope optical systems.
For fluorescence-testing with long- or shortwave light.
