Laser unit

This unit is designed to guide the laser beam into the optical-fiber cable for excitation light. With this
system, you can use the two-laser unit employing up to two lasers or the three-laser unit utilizing a
maximum of three lasers.
Two-laser unit
This unit can incorporate a total of two lasers  namely, one air-cooled argon laser and one
He-Ne or solid-state laser.
• Air-cooled argon laser: 488 nm output (manufactured by Spectra-Physics; Model 161C-030)
• He-Ne laser: 594 nm output (manufactured by JDS Uniphase; Model 1677P)
• Solid-State laser: 532 nm output (manufactured by JDS Uniphase; Model CDPS532M-020)
Three-laser unit
This unit can incorporate a total of three lasers  namely, one air-cooled argon laser and two
He-Ne lasers, or one air-cooled argon laser, one He-Ne laser, and one solid-state laser.
• Air-cooled argon laser: 488 nm output (manufactured by Spectra-Physics; Model 161C-030
or 163-C02)
• He-Ne laser: 633 nm outputs (manufactured by JDS Uniphase; Model 1144P) or 594 nm and
633 nm outputs
• Solid-State laser: 532 nm output (manufactured by JDS Uniphase; Model CDPS532M-020)
Whichever unit is chosen, the motorized shutter and the ND filter are provided in the laser
optical path to allow opening/closing of the shutter and adjustment of laser intensity by that
laser alone.
The laser unit has been precision-aligned to guide the laser beam into the optical-fiber cable.
Never touch the air-cooled argon, He-Ne laser, Solid-State laser, or excitation light optical-fiber
cable. Contact your nearest Nikon representative if you find it necessary to detach the laser head
from the laser unit due to laser failure or other problems.
