The BLP series alignment tool,  allow a single operator to install the RK series detectors quickly and easily.

The BLP units equipped with laser optically pointed with the detector optics, so the laser point where the detector optics point.

For the reflective model (RK+FX) the laser aligner is placed on the detector optics clearly, while for models (TX+RX) with separate transmitter and receiver the BLP will only be on the TX unit.
