Quality Control

Quality Control

In industrial manufacturing, micrometres often decide between quality and rejection. Surface cracks, faulty welds, porous coatings – such defects remain hidden to the naked eye but later lead to expensive claims. A professional stereo microscope makes all the difference: it reveals what would otherwise go unnoticed and transforms quality inspection from spot checks into systematic control.

Why optical magnification is indispensable in quality control

The visual inspection of manufacturing parts requires more than just good lighting and keen eyesight. Hairline cracks in surfaces, cold solder joints, inclusions in coatings – these flaws only become apparent under magnification. With the stereo microscope, inspectors can identify the characteristic structures and colour differences that indicate quality defects.

The true-to-colour, three-dimensional image provided by the Kaps stereo microscopes offers excellent depth of field, making even the tiniest details visible. Surfaces can be realistically assessed, and material defects are immediately detectable. The importance of good optics is particularly evident in the inspection of weld seams: pores, cracks, and bonding errors become visible before the part leaves production.

High Depth of Field

The true-colour, three-dimensional image of the Kaps stereo microscopes reveals even the smallest details. Surface structures at various levels remain consistently sharp, requiring no constant refocusing when examining complex geometries.

Daylight Quality

The LEDone light source of the SLM series provides illumination of daylight quality. Material colours are accurately reproduced, and surface defects are immediately apparent.

Fatigue-Free Operation

The ergonomic design allows the examiner to work precisely and without fatigue. The upright sitting posture significantly reduces strain, even during shift work.

Documentation at the Push of a Button

With an optional DSLR photo tube for Canon and Nikon or an HD photo adapter for Sony Alpha, findings can be documented directly. Multi-coated anti-reflective high-end optics ensure full-frame, distortion-free images.

Modular Expansion

The proven modular system allows for the easy adaptation of accessories at any time. Observer devices for training or documentation accessories can be added as needed.
