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)

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)

FTIR transmission windows - round,square,drilled, and customized. Transmission spectroscopy is one of the basic techniques for IR analysis. The sample and wavelength to be analysed determine the choice of window material, path length and window arrangement. (read more)
