21 Jun 2021 LASER COMPONENTS offers a range of hollow retroreflectors from partners PLX Inc, featuring state of the art accuracy and unique ability to withstand harsh environments. For modern FTIR long-path spectroscopy over a wide range and long distances, we provide PLX hollow retroreflector arrays™ (HRA). Standard retroreflector arrays are comprised of individual 2.5” clear aperture hollow retroreflectors of either 5.0 or 20.0 arc seconds maximum deviation, individually mounted on an aluminium plate. The retroreflectors are spaced very tightly together so that the array acts as one large self-compensating mirror surface. The plate is shock mounted in a durable steel housing with a single protective door. The HRA provides high quality wavefronts for perfect parallelism between incoming and outgoing beams for high efficiency returns.
