  KENTEK Corporation
  Edge Filters, Long Wavelength Pass Filters
  Kentek's ACRX-800 Long Wavelength Pass Filter is designed to pass light beyond 800nm while attenuating light below. 5% Transmission ≥ 771nm, 50% T = 800nm ± 6nm, 80% T ≤ 825nm, PLT 0.0%. Absorptive dyes are homogeneously dispersed in both polycarbonate and acrylic to create edge or long wavelength pass filters. Such materials can be conventionally molded, extruded and fabricated into a filter with any desired shape or configuration. Available in 6.5" x 6.5" polycarbonate plates... (read more)

  Infrared Long Wave Pass Filters - Standard
  Long wave pass filters provide a sharp cut-off below a particular wavelength. Often used for order sorting, they isolate broad regions of the spectrum, simultaneously providing high transmission of desired energy, and deep rejection of unwanted energy. Constructed of hard, durable first-surface dielectric coatings on optical-quality IR-transmitting substrates, Andover's Infrared Long Pass filters will withstand normal cleaning and handling associated with any high quality optical component...

  Long Wave Pass Filter for 8-12um
  Long wavepass filters are designed to achieve efficient separation of adjacent spectral bands. The cut-on edge of the filter may be located between 0.85 and 11 microns. Substrate: Germanium. Transmission: Typically >90% at wavelengths longer than the cut-on edge. Extent of transmission region is typically in the ratio of 2:1. Attenuation: Typically <0.1% at wavelengths shorter than the cut-on edge. Edge Slopes: Typically between 3% and 5%. Environmental. Adhesion MIL-C-48497A, 08/09/1980... (read more)

  COLD MIRRORS
  Cold mirrors are a special case of blocking short and passing long waves. Typical "Cold mirror" reflects wavelengths shorter than 700 nm. In this case 830 nm is selected as a half-maximum T point, cut-on point is 800 nm, and 700 nm is cut-off point. These filters can be use to reduce "noise" illumination in the visible and increase quantum efficiency for NIR detection. They are commonly used in night vision camera systems. They are also used as IR illumination filtration. One can illuminate... (read more)

  Color Correction Filters
  unwanted wavelengths from the optical path and are available in two formats: Short Pass (SP) - transmits shorter wavelengths and rejects a longer wavelengths. Long Pass (LP) - transmits longer wavelengths and rejects shorter wavelengths. SP and LP filters are useful in applications where spectral noise reduction is important or for isolating a particular region of the spectrum. Color correction filters have many useful applications in a wide variety of industries: Machine vision. Photography... (read more)

  Bandpass Filters
  point. T 5% @ 860 ± 5 nm. Cut-off point. T 5% @ 945 ± 5 nm. According to 2% convention this filter is categorized as broadband. Most of the band-pass filters are designed either by combining long-wave and short-wave pass filters (broadband) or by utilizing Fabry-Perot multi-cavity design approach (narrowband). In vacuum ultraviolet, below 200 nm where very few materials transmit design of efficient transmission band-pass filters is basically impossible. One solution is to utilize several... (read more)

  Vacuum Ultraviolet Notch Filters
  Most of the band-pass filters are designed either by combining long-wave and short-wave pass filters (broadband) or by utilizing Fabry-Perot multi-cavity design approach (narrowband). In vacuum ultraviolet, below 200 nm where very few materials transmit design of efficient transmission band-pass filters is basically impossible. One solution is to utilize several band-reflection filters and use them as a multiple reflector filtering system where incident radiation is reflected from each... (read more)
