Crystalline material UV Band Pass Filters (available crystalline materials - NiSO4*6H2O (NSH) and K2Ni(SO4)2*6H2O (KNSH)), neutral density reflective type filters made from Corning 7059 glass and designed to operate at 400-2000 nm range, neutral density absorption type filters designed to operate at VIS (450-650 nm) and Schott color glass filters.
OD 6.0 Notch Filters are designed to block specific laser wavelengths. While these optical filters reject a very narrow wavelength range (FWHM ±15-20 nm), they feature broad transmission ranges (pass bands). Custom Notch filters available on request.
EKSMA OPTICS neutral density (ND) filters attenuate VIS spectral region. The optical density varies from 0.1 to 3.0, 1 or 2 inches size square and round shapes are available.
Color Glass Filters are made from optically polished highest quality Schott colored optical glass. The spectral properties of these color filters are uniform over the entire aperture and independent of angle of incidence.
In systems for laser beam diagnostics with CCD-cameras, measurement of laser power, pulse energy and pulse duration, spectroscopy, a set of bandpass filters for mercury lamps, laser lines, and other needs are available.
