Class 2 Lasers
Class 2 lasers are lasers that emit visible radiation in the wavelength range from 400 nm to
700 nm, where eye protection is normally afforded by aversion responses, including the
blink reflex. This reaction may be expected to provide adequate protection under
reasonably foreseeable conditions of operation, including the use of optical instruments for
intrabeam viewing.

Class 2 Laser Safety Notes
Low-power lasers are, by definition, incapable of causing eye injury within the duration of a
blink (aversion response) of 0.25 seconds. They also must emit only visible wavelengths
(400 to 700 nm). Therefore, an ocular hazard may exist only if individuals overcome their
natural aversion to bright light and stare directly into the laser beam.
Class 1 Laser Models (LM80 Models)
Class 1 lasers are lasers that are safe under reasonably foreseeable conditions of
operation, including the use of optical instruments for intrabeam viewing.

Installation Instructions
Sensor Installation
Note: Handle the sensor with care during installation and operation. Sensor windows soiled by fingerprints,
dust, water, oil, etc. may create stray light that may degrade the peak performance of the sensor. Blow the
window clear using filtered, compressed air, then clean as necessary using 70% isopropyl alcohol and cotton
swabs or water and a soft cloth.
Install the Safety Label
The safety label must be installed on or near the LM sensors.
Note: Position the label on the cable or near the sensor in a location that has minimal chemical exposure.
Figure 3. Typical installation; other mounting options are possible.
1. Remove the protective cover from the adhesive on the label.
2. Wrap the label around the LM cable, as shown.
3. Press the two halves of the label together.
