VariSpec

Wavelength Tuning for Multispectral Imaging

VariSpec™ filters perform like high quality interference filters with one superior 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 Caliper Life Sciences, Cambridge Research & Instrumentation, Inc. (CRi) - a leading provider of tunable wavelength imaging filters - has manufactured and distributed thousands of the award-winning VariSpec Liquid Crystal Tunable Filters (LCTFs) over the past decade.

• Solid-state design - no moving parts
• Exceptionally compact form factor with large working apertures
• Continuous wavelength tuning ability across hundreds of nanometers
• Rapid, random-access wavelength selection
• 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. They are also used in outer space on the International Space Station.

For a turnkey imaging solution, our Nuance™ FX, Nuance™ EX, TRIO™, Vectra™, and Maestro™ imaging systems are unsurpassed in both ease-of-use and multispectral imaging power.
