LU-N3/LU-N4 Laser Units

Request a Quote

Nikon's all-new compact, alignment-free laser units.

LU-N4 Laser Unit is equipped with four lasers (405nm, 488nm, 561nm, 640nm), while LU-N3 Laser Unit has three lasers (405nm, 488nm, 561nm). Setting up is easy, just connect the fibers to the system, as each laser is pre-installed and pre-aligned.

LU-N4/LU-N3 is equipped with the newly developed laser combiner, which prevents alignment shift even after long-term use while improving laser output stability.

The built-in AOTF allows laser power to be independently controlled and modulated.

Dedicated laser unit controllers for different system configurations can be mounted on the laser unit to conserve space.
