Single Layer Magnesium Fluoride (MgF2) is the most common anti-reflection coating. It is a hard, durable coating that reduces surface reflectance of BK7 from approximately 4% to less than 1.3% at the specified center wavelength and normal incidence. Reflection losses for higher index materials such as sapphire are less than 0.5%. (read more)

Witness samples allow testing without handling the actual part, to ensure the coating process is accurate before moving forward with the optical component. (read more)

Silicon Optical Components are used in a variety of infrared applications operating in the 1.2 - 7μm wavelength range, including NIR imaging or IR spectroscopy. Silicon features a Knoop hardness of 1150, making Silicon Optical Components harder, less brittle alternatives to comparable Germanium Optical Components. (read more)

A cylindrical lens is typically used to focus, condense or expand incoming light. A cylindrical lens has one cylindrical surface, causing light to be focused in a single dimension or axis. It can also be used to expand the output of a laser diode into a symmetrical beam. (read more)
