Ball Lenses
Ball lenses are used for various tasks such as improving the coupling between optical fibers and the emitters or detectors they interface with. Standard size lenses range from 1.0mm to 5.0mm. Custom-made sizes or special materials are also available. All Ball Lenses can be ordered with full-surface anti-reflection (AR) coating..
The effective focal length of a ball lens is given by the following formula:
BFL = F – D/2 and EFL = nD/4(n-1)
The Numerical Aperture, NA, of a ball lens is dependent on the focal length of the ball and on the input diameter, d.
NA = 2d(n-1)/nD
Specifications

Drum Lenses
A Drum Lens is a variation of a ball lens where a portion of the ball is ground down to a smaller diameter. These lenses are used in similar applications to those of ball lenses. The drum lens adds the ability to handle and package it in a different way.

OCR 100
Recognition + Overall Optimization
Character Recognition or Optical Character Recognition is one of the most demanding tasks made of digital processing. In doing so, maximum reading security for all kinds of inscriptions and the ability to adapt to customer-specific requirements, form prerequisites for optimum results.
The OCR100 an integrated sensor for detecting optical characters is of modular constructions and can be used on almost every surface. Owing to its integrated sensor concept and robust construction, the OCR100 is especially suitable for industrial use, e.g for markings inscribed on metallic surfaces (automobile and supplier industries), needle-punching, laser-written text, inkjet inscription and also for detecting sell-by dates on foodstuffs packaging.

The surface quality of a product - particularly in the automotive industry - constitutes an important criterion for the customer and is generally seen in close relation to the quality of the overall vehicle. Even inevitable disturbances at the early production stages prior to applying the paint work (e.g. in the press shop or body shop) may cause defects such as dents, bumps, sink marks, etc. which might not be visible to the eye while the vehicle is still unpainted. On a high-gloss paint surface, however, even the slightest irregularities are clear to see with incident light from the proper angle, and constitute a reduction in quality. Particularly the intense competition among manufacturers demands an increase in the surface quality in conjunction with continuously decreasing production costs.
The target freedom from defects is time-consuming and labor-intensive to achieve for automobile manufacturers. It is not 100 % possible through conventional means so that defects that have gone unnoticed during the production process generate very high rework costs. Now, the early and complete detection of surface defects with the effective ABIS II high-precision surface inspection system opens up new perspectives in quality assurance.

Fault Detection, Surface Inspection
KW TRIO
Your demands for a reliable and flawless detection of extrusion faults and surface defects are ever increasing. This applies to extrusion, jacketing, enameling, drawing, and many other areas. For this reason the use of optical fault detectors ("lump detectors") is very popular. These photometric detectors are able to detect small lumps, neckdowns, and other defects on wires, cable, tubing etc., without being influenced by product parameters, line speed, vibration etc.
Important Features:
-3 times higher detection reliability (TRIO models) than conventional 2 axis systems
-Theoretically unlimited life expectancy
-Non-sensitive to stray light
-Flexible mounting concept
-Integrated air curtains for cleanliness of windows
-Defect classification and printout
-All data ports like RS-232, RS-422 and RS-485 as well as analog and PROFIBUS DP are available.

Different object colours and surfaces can heavily effect the detection behaviour of an energetic switch. With purely energetic evaluation, it is, for example, not possible to detect a black object in front of a white background.The white background reflects more light than the object itself.
In order to deal with such applications reliably, the background suppression procedure was developed. In this procedure, both the light reflected by the background and by the object is evaluated.The light is captured by two different receiver elements. With this procedure, it is possible to reliably detect e.g. a dark object on a light color conveyor belt.
There are two different procedures for the physical realisation of background suppression. In general, a distinction is made between a fixed and adjustable background suppression. With a fixed background suppression, the transmitter and receiver elements are rigidly mounted.
The laser units are particularly suitable for the detection of very small objects. With larger objects, a red-light or infrared sensor should be used. Only the background suppression procedure enables the detection of a dark object on a light conveyor belt.
