VariSpec™ Liquid Crystal Tunable Filter
The VariSpec™ Liquid Crystal Tunable Filter (LCTF) is like a high-quality interference filter, but the wavelengths of the light it transmits are electronically controllable, providing rapid, vibrationless selection of any wavelength in the visible and near-infrared tuning ranges.
The VariSpec filter's unlimited wavelength selection and excellent image quality are particularly valuable in a wide variety of applications such as remote sensing, airborne hyperspectral imaging, Raman chemical imaging, and semiconductor process control.
If you are interested in a turnkey solution for multispectral imaging, see our Nuance™ 2 imaging systems. Nuance systems incorporate VariSpec technology in a powerful, intuitive solution for microscopy in the laboratory or in the field.
Micro*Color™ and Macro*Color™ Tunable RGB Filters
The Micro*Color™ family of sliders and optical coupler-mounted liquid crystal RGB filters brings precise quantitative color to microscopy, while the Macro*Color™ RGB filters offer a large-aperture for OEM applications.
By taking each red, green, or blue color plane in sequence, and in perfect registration, these filters capture exact color information at each pixel with no spatial interpolation necessary. This effectively triples the resolution in comparison with an ordinary "painted" pixel CCD camera, where only one color is recorded per pixel. This also avoids the color shading inherent in designs that use three CCDs, and the complexity of pixel-shift systems.
Roper Industries® is the exclusive worldwide distributor of Micro*Color RGB tunable filters. In addition, Quantitative Imaging (QImaging™) incorporates Micro*Color filters into compact accessory modules that can be attached to their industry-leading FireWire™ cameras. Some models utilize circuitry that directly drives the filters, simplifying operation and optimizing performance.
