NPL models have reflectorless capabilities that expand the environments you can survey without sacrificing speed or accuracy you can survey in areas where using a prism would be impossible or dangerous. NPL models use an eye-safe Class 1 laser to measure points with a ±(5+2 ppm x D) accuracy. You can also use NPL models with reflector sheets or a standard prism, and independent measurement keys let you switch back and forth between prism and prismless modes with single-button simplicity.

Nikon Pulse Laser Stations are equipped with the unique coaxial focusing system reflectorless EDM technology. Otherwise inaccessible points can now be surveyed reliable and accurate due to Nikon's unique reflectorless EDM technology
This system focuses the laser on the object that is to be measured. The focusing of the laser beam on the object assures greater accuracy, especially when the measurement beam is oblique to the target surface.

The focusing system also automatically reduces the risk of erroneous measurements caused by passing objects such as e.g. cars, persons or the leaves of trees or bushes that interrupt the line of sight.
Through this unique technology the NPL-302 Series pulse laser stations offers superb reliability in reflectorless measurements.
The size of the laser beam can be examined as the diameter of the laser beam is etched into the reticle.
Offers a distance measurement accuracy of up to ±(3 + 2 ppm x D) mm to prisms. The NPL-352 includes a dual-axis compensator.
Will measure reflectorless to white targets at up to 210 m. Even offering these long range reflectorless measurements they still are equipped with a Class 1 laser.
Uses Nikon's world-renowned optics, the telescope ensures bright and sharp images in all conditions.
Large internal memory
The NPL-302 Series instruments feature a large internal memory. Up to 10,000 records can be stored. A maximum of 32 jobs can be created to manage the data.
