These instruments measure distances and coordinates to a very high degree of precision. As a single surface invariant reflector, the BMR’s provide great accuracy, together with a constant optical path difference. This is especially important because it allows accurate distance measurement without the need to account for refraction, a common problem when using solid, prism type retroreflectors.
The BMR’s are manufactured in three different diameters: 1 1/2, 7/8 and 1/2 and, are available in two centering accuracies, .0005 and within .0001.
PLX unconditionally guarantees their BMR’s to provide superior performance and compatibility with laser tracking systems from all manufacturers.
Should the optical elements of your BMR ever become damaged, PLX can replace them with units of comparable accuracy and alignment to the original at a modest cost.
