Every Semrock filter is hard-coated for durable performance. Ten year warranty.
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).
