Hologram Laser
LT0H12M
TEC N 940525
Hologram Laser(1 beam) for Magneto-Optical disk
s Features
(1) Maximum optical output: 35mW
(2) Pickups reduced in size and weight on request
(3) The housing of pickups shifted from aluminum
die-cast to formed resin on request (reducing the
weight to 1/3)
(4) Since its semiconductor laser, signal detection
photocell, and circuit array are assembled in a
package, the optical pickup is simple in
assembling and adjustment
