Shortpass FiltersFilters

VIS Pass/NIR Block- SP Series

Often thought of as “IR-cut” filters, Shortpass Filters are specifically designed to pass a broad spectrum of shorter wavelength light, while blocking longer visible (VIS) and near-infrared (NIR) wavelengths.

Overview

Shortpass Filters VIS Pass/NIR Block

Often thought of as “IR-cut” filters, Shortpass Filters are specifically designed to pass a broad spectrum of shorter wavelength light, while blocking longer visible (VIS) and near-infrared (NIR) wavelengths.

 

  • Designed to have a sharp transition between shorter wavelengths (which are passed) and longer wavelengths (which are blocked)
  • Peak transmission ≥90%*
  • Can be used with Longpass Filters for a custom, fine-tuned Bandpass Filter
  • Anti-reflection coated for maximum transmission
  • Exceptional surface quality; 40/20 scratch/dig
  • Available in wavelength ranges from 340nm to 785nm

*Peak Transmission SP701 = 85%, SP705 = 88%

 

SP Series – Near-IR Block

  • Commonly placed over the camera’s image sensor to block NIR light and achieve natural color rendition
  • Used as a hot mirror to reduce unwanted heat build-up caused by IR radiation
