Harmonic separators are dichroic beamsplitters used to reflect one wavelength and to transmit the others. Reflectance is better than 99.5% for the wavelegth of interest?and transmittance is at least 90% for the rejected wavelegths. The rear surface of harmonic separators?is antireflection coated.

| NOTES! |
|
|
The reflectance curves are based on actual measurements and may be different with production lots. |
|
The surface flatness is the reflected wavefront distortion of the surface befor coating. |
|
Be sure to wear laser safety goggles when checking optical path and adjusting optical axis. |
