Diamond cut optics reduce glare and hot spots

Employing single focus diamond cut lenses, the two new series of Verbatim LED spotlights mimic the warmth and dimming characteristics of halogen lamps that lighting professionals demand along with exceptional beam management and high brightness. The PAR16 GU10s and MR16 GU5.3s achieve precision-finished optical surfaces, due to the diamond cutting, which allow light to be dispersed in a defined manner, avoiding the glare, stray light and hotspots associated with many competing products.

Diffractive Optics

Diffractive Optics
Diffractive optics continue to edge their way into industry.  Applications include laser micro-machining, skin treatment and spectroscopy.  Of course, different elements are optimised for each of these, for example a Top Hat DOE would ideally be used for laser welding.  The uniform image area and sharp edges create a clear border between treated and untreated regions. LASER COMPONENTS is able to provide homogenisers, beam samplers and multispot DOEs, all of which are offered as standard elements or customised for demanding applications.
