Product Family Description

  • Common Diode, Gas, and Solid State Laser Lines
  • Variety of Bandwidths for Each Laser Line
  • Excellent Blocking Outside of Passband

Our Laser Line Interference Filters are available with a variety of bandwidths and transmission values to suit a multitude of laser applications. Ultra-narrow bandwidths as low as 1.0nm are ideal for eliminating noisy spontaneous emission from laser sources. Wide bandwidths are ideal for eliminating background noise when detecting the laser, improving a system’s signal-to-noise ratio. All filters are available mounted in 12.5, 12.7, 25mm, or 25.4mm diameter rings, easing handling and making them ideal for integration into OEM systems. Filters can also be easily mounted into our family of C-Mount Thick Lens Mounts.
