Test & Measurement

The Opto Imaging Modules are available with integrated diffuse LED ring light illumination (fully or segmented controllable) as well as a coaxial incident light LED.

Various magnifications, working distances and optical contrast methods are available within the different form factors.

USB3 or GigE versions for machine builders and integrators.


Typical applications are:

- SMD testing
- Image based hardness testing
- Crimp analysis 
- Quality and control requirements
- Documentation units
- Industry 4.0 - Sensor solutions
- Overview and detail digital zoom

Solutions for ...

Optical quality control

Test & Measurement refers to all industrial applications where microscopic structures have to be displayed and analyzed.

Here are some examples where the imaging modules are used:

- Semiconductor technology, SMD inspection, solder joint analysis
- Automotive, quality control, process control, cylinder inspection
- Metallography (hardness testing, crimp analysis, weld inspection)
- Energy, solar wafer inspection

Fabrics, filters and sieves - measuring and classifying

Optical measurement of mesh sizes with the compact 'Profile Projector'

In contrast to mechanical testing methods with test sand or glass balls, optical measurement of mesh dimensions is a fast and reliable measuring method and ideal for inline control of manufacturing results in an Industry 4.0 environment.

Wafer-Screening mit einem IM·compact M Digitalmikroskop

An IM-compact M digital microscope is ideally suited for analyzing reflective wafer surfaces and displaying the smallest structures.

The following features are unique in a single vision sensor:

- integrated coaxial top-view brightfield illumination
- compact and robust design 
- quick change between different modules
- apochromatic corrected microscope optics with long working distance
- 5MP IMX Sony image sensor
- open software architecture with own SDK


Weld seam inspection

The analysis of welding results is a typical challenge for metallography laboratories. The Machine Vision Microscope (MVM) with coaxial and ring light illumination is perfect for micro weld inspection.

A digital plug & play microscope.

- System magnification: 3.75x
- FoV [mm]: 2.3 x 1.9
- Working distance [mm]: 37
- Measuring resolution [µm/pixel]: 0.9
- Sensor: 5MP Sony IMX264 monochrome
- Interface: USB 3.1 Gen1

With the free OptoViewer it is also possible to easily perform pre-calibrated measurements.


Hardness test (Vickers & Brinell)

Microhardness testing requires very high quality optical microscopy images. Opto has been supplying imaging modules to this industry for years.


solinoTM offers considerable added value in this respect:

- using reflection analysis, micro indentations or other anomalies on a large surface can be detected

- with a standard camera, the position of a μm-sized incision within a large area can be determined

- due to the solinoTM technology used, the 'Vision' setup is independent of the object surface or ambient light conditions
