Particle Detection in cotton fibers
![]() |
[21/2009] When processing cotton fibers, it is important that foreign particles are detected and removed with as little loss of fiber as possible, to ensure optimum preparation for spinning. The new foreign particle separator from the Trützschler company in Mönchengladbach, SECUROPROP SP-FP, features an illumination unit with polarized light. The cotton fibers are transported past special cameras, which scan the fibers for foreign particles. These cameras are made by LINOS.
Foreign particles in cotton processing fall into two distinct categories: on the one hand, there are particles that differ significantly from the cotton in color, contrast and structure. The second category is made up of light-colored or transparent materials which can hardly be distinguished from the cotton by color, and are thus invisible to conventional foreign particle separators...

Tailored Raman spectrometer
![]() |
[21/2009] Raman spectroscopy is an indispensable tool in chemical, biological and biomedical analysis. It provides a high density of information regarding the chemical composition and molecular structure of the samples tested. Until just a few years ago, prohibitively high cost of Raman spectrometers meant that these instruments were found only in the research laboratories of large companies and research facilities.
Thanks to rapid developments in the field of diode lasers and CCD camera technology in recent years, subassemblies are now available that enable a more economically priced construction of Raman spectrometers. As a result, Raman spectrometers are finding their way into market segments where their use was simply not feasible until today....

New Tool in WinLens 3D
![]() |
[21/2009] In addition to numerous improvements and additions, such as the implementation of prisms and mirrors for simulating folded optical systems (see optolines Issue 20), WinLens 3D has a new utility, called "Prepare Quotation Request." This tool lets you prepare itemized lists based on previously simulated optical systems.

Machine Vision: Lightning
![]() |
[21/2009] Many of the lighting techniques commonly in use today have their origins in microscopy. Today, thanks to continual development over the years, they meet the stringent demands of industrial image processing. This is due in large part to the advent of the ISO-9000 standards, in which industrial image processing systems are used for quality assurance and documentation. Another area of application is in production, where yield and costs have been optimized through automation; for example, in the manufacture of chips for electronic equipment. The following outline is intended to provide assistance in selecting the best illumination for vision sensor applications...
An image produced by a camera shows the light reflected from an object onto the camera's sensor chip. For subsequent image processing, it is important that the object shown in the image field can be reproduced reliably and with high contrast. Thus it is essential that the illumination be optimized for the reproduction of the object in question...

New Dimensions: WinLens 3D
![]() |
[20/2009] For 15 years now LINOS has offered WinLens, the user-friendly optical design program for research, education and industry. Starting this June, on the occasion of its 15-year anniversary, a comprehensively expanded and optimized WinLens edition will be available, with new tools and functions for design, analysis and optimization of folded 3D systems. Prisms and diffraction coordinates, tilting and decentering of optical components can be simulated quickly and easily, while WinLens remains as user-friendly as ever.
A wide range of different requirements and influencing variables must be taken into account in professional optical design. In the first step, the required parameters must be determined and calculated, such as image and object focal distances, image and object sizes, aperture, focal length(s) and more...

Innovative laser beam splitter: Holographic lens
![]() |
[20/2009] A new type of beam splitter enables optical applications in laser technology and in continuous beam analysis of high-power lasers that up to now could not be implemented. The optical characteristics of this innovative beam splitter can be integrated into the lens subassemblies of laser processing centers.
The new beam splitter uses a buried holographic lens. With the function patterns tested to date, the division ratio reached was 1:1,000 and 1:10,000. The division ratio is virtually independent of the polarization. This innovative beam splitter consists of two wedge prisms that are cemented with a gap...

Prof. Viöl: New head of Laser Laboratorium, Göttingen
![]() |
[20/2009] As an industry-oriented research institute, the Laser-Laboratorium Göttingen (LLG) specializes in practical laser research and is regarded in its field as something of a "think tank." Time and time again, showcase projects and new startups have had their origin here, arising for the most part from close partnerships with the University of Göttingen, the Max Planck Institutes and HAWK University of Applied Sciences and Arts as well as both regional companies and global players. As of 1 December 2008, Professor Wolfgang Viöl replaced Professor Gerd Marowsky as CEO of LLG.
Wolfgang Viöl, professor at the HAWKof Applied Sciences and Arts in Göttingen since 1994, is exactly the right person to head up LLG. With his courage in tackling important issues and his outgoing, communicative nature, he has always been one to take the broader view...

Adjustable short-pulse laser
![]() |
[20/2009] Short-pulse lasers are making a major contribution to advancements in miniaturization and in the development of new analytical and treatment techniques, particularly in production technology and medical engineering. Pulse energy and pulse duration play a large role in these technologies; in materials processing, for example, they directly affect the processing quality and thus delineate the specific field of application for each laser source.
Passive mode-locking generates brief laser pulses in the sub-nanosecond range and is ideal for creating rugged laser systems, for example for processing temperature-sensitive materials.

25 Years of F-Theta-Ronar: In conversation with Ernst Rothe
![]() |
[20/2009] The excellent quality of the versatile, high-precision F-Theta-Ronar lenses from LINOS is a testament to decades of experience at both Rodenstock and LINOS. The 25-year history of these lenses is marked by immense customer satisfaction, and has established LINOS as a leader in laser technology.
Ernst Rothe of LINOS in Munich was instrumental in the success of the F-Theta-Ronar lenses. For 25 years he headed up research and development at Rodenstock and actively accompanied F-Theta-Ronar from the initial product idea to series production. As a pioneer in innovative handling ...
