A near-infrared (NIR) bandpass filter is a type of optical filter that selectively allows light in the near-infrared range of the electromagnetic spectrum to pass through while blocking unwanted light. The NIR range typically covers wavelengths between 700 and 2500 nm. Coligh is capability is 700nm-1600nm.
The typical wavelength of NIR bandpass filter is 780 nm, 818nm,
850 nm, 875nm, 905nm, 950nm, 980 nm,1064 nm, 1100nm,1300 nm, 1450nm, 1550 nm
It’s important to consult with Coligh to ensure that the specified wavelength meets your specific requirements. Coligh can also provide guidance on selecting the appropriate filter technology and design to meet your application needs.
