Request InfoElk Industries, R-K ManufacturingElk Industries LLC has released a patented optical element for lasers, a four-sided pyramid that can be used as a 0° reflector to reflect laser or other optical beams or rays back toward the source when the beam is directed through the base toward the apex of the pyramid. A beam also can be directed through one of the triangular faces of the pyramid toward the base and reflected outward through the opposite face of the pyramid. When used as a prism, the pyramid breaks up a spectrum of light into its component colors. The elements exhibit total internal reflection at certain angles,...See full productRelated content from Photonics MediaPRODUCTSPhotonics Showcase June 2023 IssueLeybold Optics IBS SeriesThe Leybold Optics IBS series offers ion beam sputtering with extremely low-loss optical coatings, ideal for the production of your high-precision coatings for laser optics, gyroscopes, metrology,...Photonics Showcase May 2022 IssueNew Beamsplitter CapabilityPG&O now has the capability to produce polarizing beamsplitter cubes that split up the S & P polarization of light with extinction ratios from Tp/ Ts 1000:1 and Rs/Rp 1000:1, which are...Promoted Content August 2023 IssueMulti-Bandpass Optical FiltersThe commercial availability of Light-Emitting Diodes at almost any wavelength combined with Multi-Bandpass Filters have enabled a completely new type of instrumentation.
