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.



Semrock, Inc., a Unit of IDEX Corporation, manufactures optical filters that set the standard in performance and reliability for the biotech and analytical instrumentation industries, as well as innovative optical filters for more general laser and optical systems applications.  All Semrock optical filters are made with hard ion-beam-sputtered optical coatings. OEM filters are manufactured in volume.  End-users benefit from a wide selection of standard catalog products that ship from stock.  Semrock’s patented and patent-pending products include its highly acclaimed BrightLine® fluorescence filters, state-of-the-art filters for Raman spectroscopy, and other unique filters for lasers and optical systems.  Semrock’s innovative filters, made possible by combining modern ion-beam sputtering with Semrock’s proprietary volume manufacturing technology, are covered under a five-year warranty.

Founded in September 2000, Semrock is based in Rochester, New York, a well-known center of optics, and has sales offices throughout the United States.  In October 2008 Semrock became a Unit of IDEX Corporation.  For additional information about Semrock, its products, and its team of international distributors, visit the company website at www.semrock.com.
