A wide variety of interference filters in the IR range is available: Bandpass filters, long-pass filters, short-pass filters, blocking filters, and dichroic splitters are included in this range of products.
Dielectric bandpass filters according to customer specifications. The infrared filters are available in the wavelength range from 1.0 µm to 20.0 µm.
Infrared filters in the range from 1.0 µm – 20.0 µm
The infrared filters offered here are largely produced according to customer specifications. You may directly access the IR filters available using our online stock lists.
Tips for Selecting the Right Filter:
The customer is free to choose the central wavelength in bandpass filters as well as the cut-on and cut-off wavelength in broadband bandpass filters.
It is important to pay attention to the tolerance.
Different standard full width half maximum values in bandpass filters (e.g., 1.1%, 2%, 4.3%, 8%, or 11%) are specified. Each specification refers to the value of the central wavelength selected.
The standard size is usually 25.4 mm in diameter. Some filters are mounted. In this case, the aperture is approximately 21 mm.
Custom sizes and filter chips are delivered without mounts.
