Fresnel retarder

Fresnel rhomb achromatic retarder is available in 3- and 5-mm clear aperture diameters and mounted in 2.5-in.-diameter divided-circle rotating mount. Useful frequency range is 0.4 to 2.0 µm. Total internal reflection produces retardation between polarizations in and perpendicular to the incidence plane.

A still from a video (link below) shows polymer microdisks being transferred to glass via laser catapulting. Laser catapulting can also be used to fabricate an array of microlenses directly on top of a photodetector array (inset), useful for directing more light onto the most sensitive parts of the detector.

For a microcrystalline SiC thin-film thermal emitter in a cavity-coupled setup (a), a platinum heater ring (b) heats the suspended thermal emitter structure while minimizing conductive losses into the surrounding substrate. The suspended region stays hot while the temperature shifts to blue (cold) in the nonsuspended region of the substrate (c). (Image credit: Columbia University)
