Filter for mid-IR bandpass applications   

BPF 4670-150   

This optical filter from Iridian Spectral Technologies has been designed to optimise the detection of spectral emission lines.

Manufactured using a sputtering process, these hard and durable filters deliver exceptionally high transmittance levels and blocking from the visible to the LWIR.

Many of the wavelengths commonly used for gas detection are covered in this range, including H2O; CH4; CO2; CO; N2O; and O3. Other wavelengths or designs can be supplied on request.
