Near-Infrared Bandpass Filters from Semrock
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 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.
Exceptional Semrock services include same-day shipping, rapid custom-sizing in under a week, and a 30-day no-hassle return policy. And all Semrock filters are covered under the company's five-year warranty.
