Meadowlark Optics Tunable Optical Filters facilitate spectral analysis of not only a collimated beam, but also more importantly an entire object. The Tunable Filter passes only a narrowbandwidth of light while blocking all others within the designated spectral range. The pass band can be shifted to a new color in the blink of an eye. This combination of pass band and speed is equivalent to thousands of dichroic or interference filters on hundreds of filter wheels. This enables the user to acquire images at thousands of different wavelengths in a shortamount of time. Applications of Tunable Optical Filters includefluorescence microscopy, absorption microscopy, Raman microscopy and solar astronomy
