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 ~1700 nm, and high transmission to wavelengths > 2000 nm. 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 (850 – 1750 nm). They are optimized for the most popular "retina-safe" lasers in the 1.5 μm wavelength range, where maximum permissible eye exposures are much higher than in the visible or at the 1.06 μm neodymium line. Applications include laser radar, remote sensing, rangefinding, and laser-induced breakdown spectroscopy (LIBS).
