Narrow band NIR filters that remain stable spectrally over a wide range of temperatures are essential for a multitude of applications, especially laser communication and LIDAR. This is why we are proud to be able to supply Omega Optical’s latest 4-cavity Fabry-Perot narrowband filters.
These have high thermal stability between -60°C and +80°C due to being fabricated from hard oxide materials and matched to their substrate. This additionally reduces angle sensitivity so the off-angle performance is improved but adjacent laser lines and ambient light are rejected due to steep edge slopes. We are able to provide this for custom wavelengths and sizes to suit your requirements.
