SWIR bandpass filter transmit the wavelength range of short wave infrared and block the other light. Coligh manuafctures SWIR band pass filter within 1000nm-2500nm. They have the key features below:
- It can work within the wavelength range 1000-2500nm
- We design the filter with high transmission above 90%.
- The substrate we use is optical glass, fused silica, silicon, sapphire. D263T, Corning glass
The FWHM varies from 15nm to 70nm
- Blocking depth varies from OD2 to OD5
- We have enough stock for 1380nm, 1440nm, 1640nm, 1650nm, 1660nm, 1720nm, 1790nm, 1810nm, 1930nm, 1950nm filters and many more in stock for quick prototype building.
These optical filters are usually used for applications like SWIR Imaging, laser LiDAR.
