Description of Laser Classes

Class 1 Lasers. Lasers that are safe under reasonably foreseeable conditions of

operation, including the use of optical instruments for intrabeam viewing.

Reference IEC 60825-1:2001, section 8.2.

Class 1 Laser Characteristics: see specifications.

Class 2 Lasers. Low-power lasers are by definition incapable of causing eye injury

within the duration of the blink (aversion response) of 0.25 seconds. This reaction

may be expected to provide adequate protection under reasonably foreseeable

conditions of operation, including the use of optical instruments for intrabeam

viewing. They also must emit only visible wavelengths (400–700 nm). Therefore, an

ocular hazard can exist only if an individual overcomes their natural aversion to

bright light and stares directly into the laser beam.

For safe laser use:

•

Do not permit a person to stare at the laser from within the beam.

•

Do not point the laser at a person’s eye at close range.

•

The beam emitted by a Class 2 laser product should be terminated at the

end of its useful path. Open laser beam paths should be located above or

below eye level where practical.

Reference IEC 60825-1:2001, section 8.2.

Class 2 Laser Characteristics: see specifications.

LASER LIGHT - DO NOT STARE INTO BEAM

CLASS 2 LASER PRODUCT

Pulse Power < 4 mW, 645 - 665 nm, 35 kHz,

5.1 uS Pulse. Complies TO 21 CFR 1040.10 &

EN60825-1:2001 except for deviations pursuant

to laser notice No. 50, dated 7-26-01.

CAUTION: Do Not Disassemble for Repair

This device contains no user-serviceable components. Do not attempt to disassemble for repair. Use of

controls or adjustments or performance of procedures other than those specified herein may result in

hazardous radiation exposure. A defective unit must be returned to the manufacturer.

Installation

To mount the QS186LEx into bracket models SMB18A or SMB46A, follow these steps.

1. Insert the laser emitter into the hole in the bracket.

2. Tighten the hex jam nut to the bracket until the emitter is held securely in place.

3. Mount the bracket using user-supplied screws or bolts. The SMB18A bracket uses M4 or #8 screws or bolts and the

SMB46A bracket uses M5 or #10 screws or bolts.

4. Check the sensor alignment, see Alignment on page 2. If you are using the adjustable bracket (model SMB46A),

tighten or loosen one or two of the precision alignment screws, using the supplied 2 mm Allen wrench, until the laser is

accurately aligned.
