Unmounted Protected Gold Hollow Retroreflector

Product Details Ideal for Redirecting Light in One Axis Hollow Design Minimizes Dispersion Replaces Solid Roof or Porro Prisms in Optical Assemblies TECHSPEC Unmounted Hollow Roof Retroreflectors are constructed by cementing two coated prisms together to form a hollow roof. The hollow design enables these retroreflectors to be used over wide spectral ranges without loss due to dispersion or absorption. Incident light is reflected 180° back towards the source with great accuracy due to the 90° ± 10 arcsec roof tolerance. TECHSPEC Unmounted Hollow Roof Retroreflectors feature a 17.7 x 17.7mm footprint and can be mounted with #17-242 and #18-537 . These retroreflectors are ideal for applications such as interferometry and optical delay lines.
