The Pulse Laser Station NPL-302 Series offers three
models the Nikon NPL-362, NPL-352, and NPL-332. The NPL-302 Series
include excellent measurement performance and extreme long battery
life. The instruments also include powerful onboard software that
remains very easy-to-use and easy-to-learn. With the introduction
of a graphical LCD display the menu selections and data entry has
become even simpler, resulting in increased productivity in the
field. The Nikon Pulse Laser Stations are equipped with the unique
coaxial focusing system reflectorless EDM. 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.
