Optical Filters
Optical filters includes: crystalline materials of for Optical UV Band Pass Filters. Available crystalline materials are NiSO4*6H2O (NSH) and K2Ni(SO4)2*6H2O (KNSH); neutral density reflective type filters that are manufactured from corning 7059 and designed to operate at 400-2000 nm; neutral density absorption type filters manufactured from neutral density color glass and designed to operate at 450-650 nm, Goggles and Spectacles for Nd:YAG or Nd:YAG+Ti:Sapphire applications and Tweezers/ Forceps for convenient handling of optical components.
Crystal materials are robust substrates from which optical filters of high purity and optical homogeneity can be fabricated.
Neutral density (ND) reflective type filters of 1'' (25.4 mm) size with optical density that varies from 0.1 to 2.5 are available.
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 roud 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.
