92% Transmisntace 980nm Short BandPass Filter Glass

92% Transmisntace 980nm Short BandPass Filter Glass   Product Overview: A 92% Transmittance 980nm Short BandPass Filter Glass is a specialized optical filter designed for applications that require the precise isolation of the 980nm wavelength while effectively blocking unwanted light, particularly in the near-infrared (NIR) and infrared (IR) regions. It combines absorption glass technology with thin-film interference coatings to achieve its performance. Specification: Key Specifications Decoded:   1. Short BandPass (SBP) Function:    · This defines the filter's core action. A "Short BandPass" filter is designed to transmit a specific band of shorter wavelengths and block longer wavelengths. In this case, it transmits light at and around 980nm but strongly rejects light at longer wavelengths (e.g., >1000nm), which is crucial for eliminating noise and heat radiation. 2. Center Wavelength (CWL) @ 980nm:    · This is the primary wavelength the filter is designed to target. The 980n…
