Spectrowave™ Color Grading Cabinet

The new Spectrowave™ Color Grading Cabinet by Dazor combines a traditional, northern daylight fluorescent- bulb grading box with a short-and-long wave ultra-violet (UV) fluorescence detection box, into a single grading cabinet for professional gemologists to grade diamonds, gemstones or pearls, consistently anywhere in the world. The traditional unfiltered daylight fluorescent bulbs have a spectrum which produces a constant standard illumination containing a portion of UV energy corresponding to that of natural daylight. Diamonds, gemstones and pearls can be graded in this energy environment, or under the influence of visible spectrum alone by hand-installing an anti-UV polycarbonate filter opaque to wavelengths below 390 nanometers. Additionally, Spectrowave™ has an optically diffused, dimmable solid state light engine which emits a smooth 5000K white light having no UV energy which may also be used to grade in the visible spectrum only. By removing the optical diffuser, the LED engine provides an excellent illumination tool
