830/12nm NIR Narrow Band Pass Filter Description
The 830/12nm filter is a narrow band pass filter with a central wavelength of 830nm and a half-bandwidth of 12nm.
- The 830/12nm filter produced by Coligh is specially designed for the extraction of 830nm target signals.
- It has excellent transmittance and can transmit light in the range of 824-836nm with a transmittance of more than 95%, which is very suitable for the extraction of near-infrared light signals.
- The narrow bandwidth design can effectively reduce background noise.
- It is suitable for high-sensitivity optical systems in the fields of medical, industrial and scientific research.
- We have flexible customization options, receiving customization of size, diameter, thickness and coating.

830/12nm NIR Narrow Band pass Filter Applications
830/12nm narrowband filter has the following applications:
- Infrared night vision system
830nm LED light source is better than 850nm and can be used in security cameras and drone night vision modules. - LiDAR
This filter can be used for the 830nm LiDAR receiver. The filter suppresses sunlight interference (350-1050nm cutoff) and improves the signal-to-noise ratio. - Fiber
830nm is a common fiber sensing wavelength. The filter isolates the grating reflection signal and suppresses the interference of pump light (such as 1550nm).
