VariSpec LC Tunable Filters
Wavelength Tuning for Multispectral Imaging
VariSpec™ tunable filters perform like high quality interference filters with an extremely useful exception - wavelengths of the light transmitted can be controlled electronically. This provides rapid, vibrationless selection of visible (VIS) and near-infrared (NIR) wavelengths.
Now part of PerkinElmer Life Sciences, Cambridge Research & Instrumentation, Inc. (CRi) - the world's leading provider of liquid crystal tunable filter (LCTF) technology - has manufactured and sold thousands of the award-winning VariSpec filters over nearly two decades.
- Solid-state design - no moving parts
- Exceptionally compact form factor with large working apertures
- Fast random-access wavelength selection across hundreds of nanometers
- Excellent image quality
- High-speed plug-and-play USB interface with Windows® DLL support, LabVIEW™ and Matlab® drivers
VariSpec filters are used in general research and as OEM components in instruments serving markets such as biomedical imaging, metrology, manufacturing QA/QC, and forensics. Our tunable filters have been flight-qualified for NASA space missions and have flown on missions by many nations, including aboard the International Space Station. Choose our VariSpec filters when flexibility, accuracy, and reliability are paramount.
