LONG WAVE PASS (LWP) 
 

Long Wave pass coatings are used to separate two regions of spectrum.
These all dielectric, high damage threshold coatings reflect the short wave region and pass the longerwavelength region.

SHORT WAVE PASS (SWP)

Short Wave pass coatings are used to separate two regions of spectrum. 
These alldielectric, high damage threshold coatings reflect the long wave region and pass theshorter wavelength region

These and other coatings are available from stock on a variety of substrates. Other wavelengths and angles of incidence can be provided upon request. Please contact us for assistance with fulfilling your requirements.
