Product documentation

Description

UV-VIS neutral density (ND) filter is spectrally flat from 200 to 700nm and feature outstanding parallelism and surface characteristics. This combination of high tolerance and broadband performance makes these filters ideal for attenuating a wide range of sources. The filter is suitable for low power laser applications. Orient mirrored side toward source at 0° angle of incidence.
