Optical coating methods: Thin films for optical systems

Modern optical coating technologies After introducing the field of optical coating, e. g. via filter and anti-reflective coatings, beam splitter and dielectric mirrors, the following article shows how to obtain the coating materials with the desired properties on optics made of glass, metal or other materials. Optical coatings are used in a variety of applications, […] Mehr

High-performance optical coating for demanding applications

Precision optical components such as lenses or mirrors are almost always provided with an optical coating. The applied layers have different effects, such as the enhancement of transmission of certain wavelengths or the reduction of reflection. However, an optical coating is not only used in optics and technology sectors, but also in everyday objects such […] Mehr

Cleaning optics properly

A guide to handling and cleaning optics The basic requirement for a long lifespan and the preservation of quality of precision optics is the high level of care in handling and cleaning. Depending on the material, the coating as well as the degree and type of contamination, various things must be considered. In the following, […] Mehr

Aspheric myths – facts and fiction

Part 1: Geometry, metrology and quality myths Aspheres are becoming increasingly important and have become standard components in many areas of application. They can be found in photo lenses with high luminous intensity or wide-angle lenses, in endoscopes, magnescope and telescopes, but also in high-tech applications such as aerospace. With the development of modern manufacturing […] Mehr

Improving focusing quality of spherical lenses

Header_Improving focusing quality
Introduction The generation of Bessel beams with axicons is the most noted application for this uncommon type of aspherical surfaces. A more complex setup (Fig 1.) of combining several axicons and a common spherical lens will be the main aspect in the beam shaping consideration within this article. It will be demonstrated how the focusing […] Mehr

Various beam shaper applications utilizing axicons

Axicons are conical lenses which create a ring-shaped beam used in research or rather different laser applications. They can be either convex or concave and made from almost any optical material. By combining two or more axicons and lenses multiple intensity profiles can be created. Specifics and Bessel beam creation Axicons are commonly used to […] Mehr
