Laser-line nonpolarizing cube beamsplitters are
particularly useful with randomly polarized lasers. In
a randomly polarized laser, polarization ratio and
direction can be time varying. Using a randomly
polarized laser with a polarization sensitive
component, can lead to changes in transmission
value over time. A nonpolarizing ielectric
beamsplitter ensures stable performance regardless
of the polarization state of the source.
Laser-line nonpolarizing cube beamsplitters are designed for applications in
which polarization effects must be kept to a minimum.Their all-dielectric construction provides negligible
absorption.

| NOTES! |
|
 |
The transmittance curve is a graph based on actual measurements and may vary from production lot to production lot. |
|
The surface flatness is the reflected wavefront distortion of the surface before coating. |
|
Plate-type nonpolarizing beam splitters are also provided upon request. |
|
Be sure to wear laser safety goggles when checking optical path and adjusting optical axis. |
