PLX Hollow Retroreflectors

A retroreflector is an optical device that reflects light back towards it’s source with minimal scattering. PLX hollow retroreflectors have state of art accuracy and a unique ability to withstand harsh environments. The retroreflectors can be coated for maximisation over any spectral range from UV to far IR and can be customised to fit your specific needs.

PLX hollow retroreflectors are already utilised in industries such as aerospace, defence and laboratory instrumentation around the world.

PLX is a Luxium Solutions brand that has been at the forefront of developing high-quality monolithic optics for over 60 years. PLX optics can withstand and perform under the harshest environmental conditions and maintain their accuracy over time.
