Overview

Longpass Filters

Often referred to as a “sharp-cut” filter, Longpass Filters are specifically designed to pass a broad spectrum of longer wavelength light while blocking shorter wavelengths.

  • ◆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
  • ◆Available in wavelength ranges from 350nm to 1500nm
