SWIR Camera filters

SWIR Camera filters

Filter type

Longpass, bandpass, narrow-band

Filter mount

Threaded (M30.5), C-mount, unmounted

25.4® C-Mount Filter mount design

  • 25.4® C-Mount Camera Filter exclusively designed by Midopt to thread directly into any C-Mount Camera between the lens and sensor
  • Recommended for use with wide angle lenses to prevent vignetting and angle shift
  • Helpful in applications with space constraints and lenses without filter threads
  • Custom installation wrench included
  • Standard Filter thickness: 1mm

Longpass Filters

Longpass Filters provide seamless transition from reflection to transmission and are available in many wavelengths, depending on the needs of your system. Longpass Filters are best used in a controlled environment when multiple wavelengths need to be passed and are an economical solution for blocking excitation light in fluorescent applications.

  • Economical solution for isolating specific spectral regions
  • Peak transmission ≥90%
  • StablEDGE® design reduces angular dependency and minimizes short-shifting effects
  • Anti-reflection coated for maximum transmission in VIS and NIR spectrums
  • Can be used with Shortpass Filters for a custom, fine-tuned Bandpass Filter
  • Double-side polished glass for exceptional parallelism and optical flatness
  • Exceptional surface quality; 40/20 scratch/dig

Bandpass Filters

Bandpass Filters are often one of the easiest ways to drastically improve image quality. They are designed with a Gaussian transmission curve to emulate the output of the most common types of LEDs used in machine vision and are great for testing the effects of monochromatic imaging. All MidOpt Bandpass Filters have an anti-reflection coating to ensure maximum transmission.

  • Designed with a broad, Gaussian passband to mimic and accommodate the entire output of the most common LED wavelengths
  • Test the effects of monochromatic illumination
  • High transmission ≥90%*
  • Superior out-of-band blocking
  • StablEDGE® design reduces angular dependency and minimizes short-shifting effects
  • Double-side polished glass for exceptional parallelism and optical flatness

Narrow-band Filters

  • 45-55nm FWHM*
  • Guaranteed peak transmission ≥85%
  • Superior out-of-band blocking
  • Designed for use with laser diodes and LEDs in applications with overwhelming ambient light
  • StablEDGE® design reduces angular dependency and minimizes short-shifting effects
  • Double-side polished glass for exceptional parallelism and transmitted optical wavefront
