Optical Filters Products

31. IR Long Pass Filters 7/18/2012

    IR Long Pass Filters improve signal-to-noise ratio in FTIR, spectroscopy, astronomy, IR detector research, THz imaging, and other mid to far IR applications by blocking short wavelength radiation. Lake Shore’s line of IR Long Pass Filters are available in diameters of 0.5 to 4 inches and feature rejection edge wavelengths from 1 µm to 50 µm, a wide and flat spectral response to terahertz (0.3 THz), and excellent thermal and mechanical properties.

32. Color Correction Filters 3/27/2012

    Abrisa Technologies provides a wide spectral range of color coatings and glass (color correction filters), from ultraviolet to infrared, and has the capabilities to meet all of your specific glass fabrication requirements. 

33. Linear Variable Filters Overview 11/29/2011

    DELTA has lifted the quality of variable filters* to new levels, by introducing a new powerful combination of linear variable filters. DELTA offers a Linear Variable Long Wave Pass filter (LVLWP), the corresponding Linear Variable Short Wave Pass filter (LVSWP) together with a Linear Variable Dichroic.

34. Bandpass & Notch Filters: Trim Filters 2/9/2011

    Trim filters, also commonly known as cut-off or dichroic filters, are advantageous for a variety of applications. Common uses include optical noise reduction for bar-code readers and wavelength band isolation for fluorescence applications. Trim filters are often used in conjunction with absorptive filter glasses to form band pass filters.
