Safety
1.4 Intended Use
- The optoNCDT 1750 system is designed for use in industrial and laboratory applications.
- It is used
for measuring displacement, distance and position
for in-process quality control and dimensional testing
- The system must only be operated within the limits specified in the technical data, see Chap. 3.3.
- The sensor must be used in such a way that no persons are endangered or machines and other material
goods are damaged in the event of malfunction or total failure of the sensor.
- Take additional precautions for safety and damage prevention in case of safety-related applications.
1.5 Proper Environment
- Protection class: IP 65 (applies only when the sensor cable is plugged in)
Lenses are excluded from protection class. Contamination of the lenses leads to impairment or failure of the
function.
- Temperature range
Operation: 0 °C ... 50 °C (+32 up to +104 °F)
Storage: -20 °C ... 70 °C (-4 up to +158 °F)
- Humidity: 5 - 95 % (non-condensing)
- Ambient pressure: Atmospheric pressure
The protection class is limited to water, no penetrating liquids or similar!

Laser Safety
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 Safety
The optoNCDT 1750 sensors operate with a semiconductor laser with a wavelength of 670 nm
(visible/red) resp. 405 nm (visible/blue). 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
(0.3 ... 7.5 kHz). The pulse duration of the peaks is regulated depending on the measuring rate and reflectivity
of the target and can be 0 up to 3333 µs.
Comply with all regulations on lasers!
i
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. 12. 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 must be attached to the cover (front and/or rear side) of the sensor housing.The
laser warning labels for Germany have already been applied. Those for other non German speaking countries
an IEC standard label is included in delivery and the versions applicable to the user’s country must be applied before the equipment is used for the first time. Laser operation is indicated by LED, see Chap. 5.3.

3. Functional Principle, Technical Data
3.1 Short Description
The optoNCDT 1750 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-resolving 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.

Functional Principle, Technical Data
3.2 Real Time Control (RTSC)
The CMOS element determines the intensity of incident light during the exposure. This enables the sensor to
compensate for fluctuations in brightness on the object being measured. What is more, it does so in a range
from almost total absorption to almost total reflection. The RTSC (Real-Time-Surface-Compensation) allows
an accurate real-time surface compensation in the measurement process with a high dynamic range.

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

optoNCDT 1750
Ideal diffuse reflection Real reflectionDirect mirror reflection
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 1750 sensors offer outstanding performance 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 applies in particular to measurement work performed in close proximity to welding equipment.
Page 23
Installation
5.1.2.2 Color Differences
Because of intensity compensation, color difference of targets affect the measuring result only slightly. However, 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 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.
5.1.2.4 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.
5.1.2.5 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.
optoNCDT 1750
Page 24
Installation
5.1.2.6 Surface Roughness
Laser-optical sensors detect the surface using an extremely small laser spot. They also track slight surface
unevenness. In contrast, a tactile, mechanical measurement, e.g. using a caliper, detects a much larger area
of the measurement object. In case of traversing measurements, surface roughnesses of 5 μm and more lead
to an apparent distance change.
Suitable parameters for the averaging number may improve the comparability of optical and mechanical
measurements.

h > 5 µm
Ceramic reference surface Structured surface
Recommendation for parameter choice:
The averaging number should be selected in such a way that a surface area the size of which is comparable
to those with mechanical measurements is averaged.
optoNCDT 1750
Page 25
Installation
5.1.2.7 Angle Influences
Tilt angles of the target in diffuse reflection both around the X and the Y axis of less than 5 ° only have a
disturbing effect with surfaces which are highly reflecting. Tilt angles between 5 ° and 15 ° lead to an apparent
distance change of approximately 0.12 ... 0.2 % of the measuring ranges, see Fig. 6.
These influences have to be explicitly considered when scanning profiled surfaces. Basically the angle behavior of triangulation is liable to the reflectivity of the measuring object surface.
