New Tunable Near-IR Bandpass Filter


ROCHESTER, N.Y. – New to Semrock’s revolutionary VersaChrome® widely tunable thin-film optical filter line-up is the TBP01-800/12, pushing tunable imaging into near-IR territory with a wavelength tuning range of over 100 nm.

Unique in the marketplace, VersaChrome filters offer wavelength tunability over a very wide range of wavelengths (> 12% of the normal incidence wavelength) by adjusting the angle of incidence with essentially no change in spectral performance.

VersaChrome tunable filters combine all the performance advantages of thin-film optical filters—including high average transmission, steep edges, and wide out-of-band blocking—with the center wavelength tuning flexibility of a diffraction grating. The complete set of bandpass filters covers wavelengths from 390 – 800 nm. Rectangular filters are immediately available from stock in 25 mm x 36 mm x 2.0 mm size, and custom-sized filters are available in less than a week.

These tunable filters are ideal for fluorescence microscopy and measurement applications, as well as hyperspectral imaging, high-throughput spectroscopy and any other optical system that can benefit from the spectral and two-dimensional imaging performance of thin-film filters. Because of their excellent polarization insensitivity and high optical quality and damage threshold, they are well-suited for a wide range of laser applications as well.

Semrock’s industry-leading and proprietary hard-coated filter manufacturing process ensures permanent performance with “no burn-out” even under the most intense illumination conditions.  Semrock filters are available from stock for same-day shipment with a 30-day no-hassle return policy and are covered under the company’s five-year warranty. Custom-sized filters are available in under a week.
