Key Performance Features
This NIR filter provides efficient, selective detection of 905nm laser, LED, or fluorescence signals while eliminating background crosstalk from visible and broad NIR sources. The balanced 26nm FWHM is ideal for maximizing signal in time-resolved measurements, outdoor LIDAR, and biomedical imaging where sharp cut-offs and high throughput are essential. Coated for long-term durability, it supports operation in both laboratory and rugged industrial environments.
Applications
- Laser rangefinding and LIDAR: Optimized for 905nm lasers to ensure precise spatial mapping and obstacle detection. - NIR imaging and fluorescence: Fast signal collection for diagnostic instruments, flow cytometers, and medical analyzers. - LED/photodiode detection: Used as a front-end filter for camera/sensor protection and IR intensity control in OEM modules. - Scientific R&D and automation: High signal-to-noise ratio for spectroscopy, quality control, robotics, and machine vision.
