Confused about the differences between traditional-coated and hard-coated optical filters?

Waveplates and retarders are optical components designed to transmit light while modifying its polarization state without attenuating, deviating, or displacing the beam.

Waveplates (retarders) are different when used in polarized light than unpolarized light. Consider terminology, fabrication, or applications at Edmund Optics.

When measuring minuscule particles, many advanced Life Science applications require more power than one laser produces.

SWIR, or short-wave infrared, is light invisible to the human eye but detectable by specialized infrared imaging lenses and cameras.
