Filter & Apertures

Harmonic separators
are a useful tool to

These are dichroic (i.e., color dependent)
beamsplitters which separate the YAG
fundamental from its second harmonic.
Three configurations are offered. One
reflects the fundamental and the second
reflects the 532nm harmonic and the third
reflects the 355nm harmonic. They are
available in four sizes 25.4mm, 30mm,
50mm and 50.8mm diameter.

quickly separate the
the second harmonic
The sizes listed here
are standard, but we
are able to provide
both larger and smaller
sizes (and other
wavelength separations
for other applications)
at competitive prices.
