HWB720 Absorption Longpass Filter | Tave Greater Than 88 Percent, 750-1100nm

The OPTOStokes HWB720 is a premium-grade absorption longpass filter engineered for precise spectral separation in the near-infrared (NIR) spectrum. By utilizing specialized doped optical glass, this filter provides a sharp cut-on transition, effectively absorbing unwanted ultraviolet and visible light while maximizing transmission in the 750-1100nm range. It is an ideal component for system integration requiring high reliability and minimal angle dependency.

Technical Specifications

Industrial Applications

Due to its excellent out-of-band rejection and uniform substrate performance, the HWB720 is widely adopted across automated systems. Key applications include industrial inspection, machine vision automation equipment, robotic sorting systems, and infrared illumination setups where visible light interference must be strictly suppressed.
