gered.
- Take additional precautions for safety and damage prevention for safety-related applications.

Laser Class
optoNCDT 1320
Never deliberately look
into the laser beam!
Consciously close
your eyes or turn away
immediately if ever the
laser beam should hit
your eyes.
2. Laser Class
The optoNCDT 1320 sensors operate with a semiconductor laser with a wavelength of 670 nm (visible/red).
The sensors fall within Laser Class 2 (II). The laser is operated on a pulsed mode, the average power is
≤1mW.Thepulsefrequencydependsontheadjustedmeasuringrate(0.25...2kHz).Thepulseduration
of the peaks is regulated depending on the measuring rate and reflectivity of the target and can be 0.3 up to
3999.6 µs.
iComply with all regulations on lasers!
Although the laser output is low looking directly into the laser beam must be avoided. Due to the visible light
beam eye protection is ensured by the natural blink reflex. The housing of the optical sensors may only be
opened by the manufacturer, see Chap. 11. For repair and service purposes the sensors must always be sent
to the manufacturer.
Lasers of Class 2 (II) are not subject to notification and a laser protection officer is not required.
The following warning labels are attached to the sensor cable.

3. Functional Principle, Technical Data
3.1 Short Description
The optoNCDT 1320 uses the principle of optical triangulation, that is, a visible, modulated point of light is
projected onto the target surface.
The diffuse part of the reflection of this point of light is displayed depending on distance on a position-resolv-
ing element (CMOS) by an receiver optic which is arranged to the optical axis of the laser beam in a defined
angle.
A signal processor in the sensor calculates the distance of the point of light on the measuring object to the
sensor by means of the output signal of the CMOS elements. The distance value is linearized and output by
means of the analog or RS422 interface.

The Auto Target Compensation (ATC) enables stable compensation independent of color and brightness of
the measuring object. Also small objects can be detected reliably thanks to the small measuring spot.

5.1 Instructions for Installation
5.1.1 Reflection Factor of the Target Surface
In principle the sensor evaluates the diffuse part of the reflected laser light.
Laser beam
Ideal diffuse reflection Real reflectionDirect mirror reflection
Laser beam Laser beam

2
Fig. 5 Reflection factor of the target surface
A statement concerning a minimum reflectance is difficult to make because even a small diffuse fraction can
be evaluated from highly reflecting surfaces. This is done by determining the intensity of the diffuse reflection
from the CMOS signal in real time and subsequent compensation, see Chap. 3.2. Dark or shiny objects being
measured, e.g. black rubber, may require longer exposure times. The exposure time is dependent on the
measuring rate and can only be increased by reducing the sensor’s measuring rate.
5.1.2 Error Influences
5.1.2.1 Light from other Sources
Thanks to their integrated optical interference filters the optoNCDT 1320 sensors offer outstanding perfor-
mance in suppressing light from other sources. However, this does not preclude the possibility of interference
from other light sources if the objects being measured are shiny and if lower measuring rates are selected.
Should this be the case it is recommended to use suitable shields to screen the other light sources. This ap-
plies in particular to measurement work performed in close proximity to welding equipment.

Page 20
Installation
optoNCDT 1320
5.1.2.2 Color Differences
Because of intensity compensation, color difference of targets affect the measuring result only slightly. How-
ever, such color differences are often combined with different penetration depths of the laser light into the
material. Different penetration depths then result in apparent changes of the measuring spot size. Therefore
color differences in combination with changes of penetration depth may lead to measuring errors.
5.1.2.3 Surface Roughness
In case of traversing measurements surface roughnesses of 5 µm and more lead to an apparent distance
change (also-called surface noise). However, they can be dampened by averaging.
5.1.2.4 Temperature Influences
When the sensor is commissioned a warm-up time of at least 20 minutes is required to achieve uniform
temperature distribution in the sensor. If measurement is performed in the micron accuracy range, the effect
of temperature fluctuations on the sensor holder must be considered. Due to the damping effect of the heat
capacity of the sensor, sudden temperature changes are only measured with delay.
5.1.2.5 Mechanical Vibration
If the sensor is to be used for resolutions in the µm to sub-µm range, special care must be taken to ensure
stable and vibration-free mounting of sensor and target.
5.1.2.6 Movement Blurs
If the objects being measured are fast moving and the measuring rate is low, it is possible that movement
blurs may result. Always select a high measuring rate for high-speed operations, therefore, in order to prevent
errors.
