Near-Infrared Bandpass Filters Now Available from Semrock


ROCHESTER, N.Y. – Semrock has announced the release of a new series of bandpass filters that demonstrate the extension of its high-performance optical filter technology to the popular near-infrared wavelength range. These highly reliable, hard-coated bandpass filters are keyed to popular laser lines in the 1500 – 1600 nm region.

The new near-IR filters 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 um wavelength range, where maximum permissible eye exposures are much higher than in the visible or at the 1064 nm Nd:YAG laser line.

Applications for these filters include laser radar, remote sensing, range-finding, and laser-induced breakdown spectroscopy (LIBS). The near-IR bandpass filters are a good match for Er-doped fiber and glass lasers at 1535 nm, Er-doped fiber and InGaAsP semiconductor lasers at 1550 nm, and Nd:YAG-pumped optical parametric oscillators (OPO's) at 1570 nm. Standard 25 mm diameter filters are available immediately from stock for $345, with custom sizes available in less than a week.

"Semrock is very pleased to be able to offer NIR optical filter manufacturing capabilities," said Turan Erdogan, Semrock's CTO.
