Hollow Roof Mirrors™ (HRMR)
Product Announcement from PLX Inc.
Ideal for redirecting light in one coordinate.
The HRMR is an orthogonal assembly of two plane mirrors attached to each other along one "roof edge." The HRMR can be used in almost every application where a "roof top" or porro prism can be used. Because the optical path is in air, there is no refraction and there is no reflecting front prism surface. It is also insensitive to tilt or misalignment in one coordinate.
Useful in all wavelengths, HRMRs are available with different accuracies and reflective coatings, and in custom configurations.
