8.4 M67 LASER AIMING OPTION
M67LR LASER AIMING VERSION
(Laser output: 630 to 650nm at <1mW, CDRH Class II)
This model incorporates the Laser Aiming option. The laser is manually activated using the push (and turn)-button on the M67
rear panel.
The switch is a Push-and-Turn with a red LED indicator nearby.. The laser is on when the LED is lit. For momentary use,
simply push the button in; release to turn laser off. To keep the laser on longer, push the button in; twist it about 45° to
clockwise to lock it in. Turn it off by twisting is 45° counter-clockwise. DO NOT LEAVE LASER ON FOR MORE THAN A
FEW MINUTES; MEASUREMENT ACCURACY WILL BE DEGRADED IF LEFT ON.
DANGER: Laser light is emitted from the M67LR front lens (opposite the rear panel). Do not
look directly at the emitted beam or reflection.
8.4.1 Aiming and focusing the M67LR
The laser is aligned to the center of the M67 field of view and is coaxial to the infrared detection system.
Mount the M67 at the desired location. Apply power (see manual). Turn on laser using the pushbutton described above. Adjust
the focus knob until the laser light is focused to the smallest spot possible. This is when the infrared system is in focus. The
laser spot is the center of the infrared field of view. Refer to the manual to determine the infrared spot size for the field of view
rating of the M67.
