VIS Pass/NIR Block- SP Series

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
