Fabry-Perot Etalons - Applications

A Fabry-Perot etalon is an interferometer of the simplest form, but it is that essential simplicity that makes it so useful in a wide variety of optical applications.

Etalons manufactured at SLS Optics are used for diagnostic and control purposes in scientific and industrial communities worldwide.

Below is a small selection of where our etalons are being employed:

• Highly specialised etalons for DUV photolithography sources
• Air-spaced etalons used to control the centre wavelength and bandwidth of UV-NIR lasers
• Large solid and air- spaced etalons for government research projects
• Etalons for telecommunications solutions
• Air-spaced etalons for astronomy as narrow bandwidth filters
• Wavelength reference etalons used in LiDAR sensing instruments for atmospheric research
