1. Safety instructions

The laser reflection sensor meets the safety regula-

tions for Class 2 lasers. It emits light in the visible

region of the spectrum (400 – 700 nm). The radia-

tion power is less than 1 mW.

Provided that the instrument is used in accordance

with the instructions, safe operation is ensured.

In schools and other places of education or train-

ing, the instrument must only be used under the

supervision of a trained and responsible person.

Do not look into the light beam - that is not

necessary when using the sensor.

• If the housing of the instrument shows visible

signs of damage, it must be taken out of use

immediately.

• Do not use any optical equipment that narrows

the light beam.

• Do not open the instrument housing.

2. Description

The instrument emits a laser beam at 630 nm

wavelength and measures the reflected light. Two

sensitivity ranges (near zone and distant zone) are

provided, to adjust the instrument parameters for

different operating conditions.

The near-zone setting (4) adjusts the instrument

parameters for operating distances of 5 to 50 mm.

The experiment should be chosen so that there are

widely different reflectivities (e.g. matt black mark-

ings on a white or diffusely reflecting background).

With reflecting foils or microprism mirrors, a larger

fraction of the light is reflected in the incident

direction, and one can then work with a beam box

up to 5 m long without special adjustments to the

mirror. In such cases one should use the distant-

zone setting (2).

By connecting the instrument to other external

technical aids, one can measure physical quantities

related to the motions of bodies, such as rate of
