Product description
The 940nm IR Narrow BandPass Filter is designed for night-vision applications, effectively isolating the 940nm wavelength while blocking unwanted light. With a peak transmission of over 85%, this filter ensures optimal performance in low-light conditions. Its robust design features a blocking band of OD>3 from 400-1100nm, making it ideal for environments where infrared detection is critical.
Key Features
- Center wavelength at 940nm for precise spectral fit in night-vision systems.
- Peak transmission greater than 85% ensures high efficiency and clarity.
- Blocking band of OD>3 from 400-1100nm prevents interference from unwanted wavelengths.
- Tolerance of ±3nm guarantees consistent performance across batches.
- Customized support available for OEM, ODM, and OBM projects.
