Laser Physics Uk Introduces Meadowlark Optics New Tri-Color Liquid Crystal Optical Filter
26 Sept 2012Designed with the most compact package yet, Meadowlark Optics Tri-color liquid crystal optical filter offers 3 user selectable channels from a wavelength range of 420-780nm. Used in applications such as fluorescence microscopy, the Tri-color filter provides the user high transmission and full video filter switching speed and, since it has no moving parts, no vibrations are caused, unlike switching traditional filters.
The Tri-color filter head weighs just 71g and can be mounted in one of three ways; 8 - 32 thread holes, optional cage systems and optional C-mount interface.
Meadowlark Optics excels at providing customized filters for a variety of applications. The Tri-color filter is factory customizable to achieve different centre wavelengths, wavelength ranges and other specifications, for example, pseudo white state, or continual tuning.
Meadowlark Optics has also updated the Selectable Bandwidth Tunable Optical Filter, enabling it to be optical cage mounted. Continuously tunable over 420-730nm with 0.1nm resolution, this filter allows the user a choice of three different bandwidth sizes at each wavelength: narrow, medium and wide, allowing the user to acquire images at thousands of different wavelengths fast in applications including fluorescence, absorption and Raman microscopy and solar astronomy.
Meadowlarks Tunable Optical Filters can also be customized to achieve different bandwidths, wavelength ranges or other performance profiles to provide a solution that meets your needs.

Liquid Crystal Tuneable Optical Filter
Laser Physics UK LtdMeadowlark Optics’ Liquid Crystal Tuneable Optical Filters facilitate spectral analysis of not only a collimated beam, but of an entire object. With no moving parts, a resolution down to 0.001nm and a tuning rate of less than 100ms, these robust filters are calibration free and can replace literally 1000s of filters for applications including fluorescence and absorption microscopy, Raman spectroscopy and solar astronomy. At 38 x 67 x 15mm and less than 60g, the Tri-Color LC optical filter is the smallest LC filter package yet and stepping between 3 design wavelengths at full video rate without introducing vibration, it easily integrates in to your imaging system via post, cage or c-mounts. Stock filters are RGB, but this filter can be customised for different centre wavelengths, wavelength ranges, pseudo white state or continual tuning. With continual tuning range over the visible spectrum at 3 selectable bandwidths, the TOF-SB-VIS tuneable filter allows the user to switch between or continuously through any wavelength from 420 to 730 nm with 0.1nm tuning resolution. Just as easy to mount into your imaging system, with its 2cm clear aperture and 6° half angle, this filter replaces thousands of filters, saving space and time between images and without introducing any vibration. Again Meadowlark Optics’ LC TOFs can be customised complete or as an OEM to suit your application needs.
