PLX Hollow Roof MirrorsTM (HRMs) are ideal for redirecting light in one coordinate and any application where a roof top or Porro prism can be used. Useful in all wavelengths, they are available in different accuracies, coatings, and configurations.

Beam Deviation is the maximum deviation from parallelism, expressed in seconds of arc, of any single return beam from any of the 6 sub-apertures of the retroreflector, when the retroreflector is fully-illuminated.

Exiting Wavefront is the resultant maximum peak-to-valley wavefront deformation from a fully-illuminated retroreflector, where lambda = 633nm.

Certain high accuracy models may be heavier than indicated here. Check with us for actual weight.
