Semrock NIR Bandpass Filters

Semrock's industry-leading ion-beam sputtering manufacturing is now available for making optical filters with precise spectral features (sharp edges, passbands, etc) at near-IR wavelengths, with features out to ~1700nm, and high transmission to wavelengths >2000nm. The bandpass filters on this page are ideal as laser source clean-up filters and as detection filters which pass particular laser wavelengths and virtually eliminate background over the full InGaAs detector range (850nm - 1750nm).

They are optimised for the most popoluar "retina-safe" lasers in the 1.5μm wavelength range, where maximum permissible eye exposures are much higher than in the visible or at the 1.06μm neodymium line. Applications include laser radar, remote sensing, range finding, and laser-induced breakdown spectroscopy (LIBS).
