Hollow Roof Mirrors™ (HRM)
- For any application where a roof top or porro prism can be used.
- The optical path is in the air so there is no refraction or reflecting front prism surface.
- Useful in all wavelengths and available in a variety of accuracies and coatings.
- Light weight aluminum housing for protection and ease of handling.
- Compatible with all major mounting systems.
- RoHS Compliant.
- PLX is a registered ISO 9001 company.
Ideal for redirecting light in one coordinate.
The HRM is constructed from two first-surface mirrors assembled by a proprietary process to form an inside corner. This inside corner forms a 90-degree angle to a very high level of accuracy. The mirrors can be coated for optimization over a spectral range from UV to far IR. This configuration eliminates material absorption and chromatic aberration.
The HRM can be used in almost every application where a roof or porro prism can be used. Because the optical path is in air, there is no refraction nor any reflecting front prism surface. It is also insensitive to tilt or misalignment in one coordinate. If the HRM is rotated about the roofline, the reflected beam direction does not change. Useful in all wavelengths, HRMs are available with different accuracies and reflective coatings, and in custom configurations. The HRM is provided in a versatile housing, which is compatible with all major mounting systems.
When ordering, be sure to add a suffix to the catalog number to indicate the desired mirror coating.

Width is measured across the roof edge direction.
Length is measured along the roof edge direction.
