Ball Mounted Hollow Retroreflectors™ (BMRs)

They have been successfully drop-tested on concrete from a height of 6 feet.

Our new DBMRs are available in 1.5” diameter and two centering options (0.0001” and 0.0005”), and are guaranteed to be compatible with laser tracking systems of all manufacturers.

All PLX Ball Mounted Retroreflectors are equipped with our standard protected silver coating for the highest durability, reflectance and distance. Our coatings are applied directly on the mirror surface utilizing the same process that is used for military applications. Other break-resistant retroreflectors have replicated mirror coatings. In this process, the mirrors are coated with unprotected gold over epoxy, which makes them very sensitive to handling and exposure to outdoor harsh environments.

Backed by PLX's history of superior quality BMRs.
