Excimer Optics: High Power Demands High Reliability
Michael A. Case, Teledyne Princeton Instruments, Business Unit of Teledyne Technologies
The first high-reflectance mirror coatings for the UV and vacuum UV (VUV) were of the Al + MgF2 type produced in the late 1950s. Coatings of this design are still used today for multigas cavity...
Common Infrared Optical Materials and Coatings: A Guide to Properties, Performance, and Applications
Jeffrey L. Tosi and Kumar M. Khajurivala, Janos Technology LLC
The optical materials selected for an optical system depend upon the application, the required system performance and the environment in which the system is to perform; thus the materials’...
Cleaning Optics: Choosing the Best Method
CVI Laser Optics
Optics can be contaminated in many ways. Contamination can be kept to a minimum by returning the optics to their case after use or by covering the optics for protection from the outside environment....
Mirrors: Coating Choice Makes a Difference
JDSU
The basic difference between the household mirror and the optical mirror is that one is coated on the back surface and the other is coated on the front. For optical applications, a front-surface...
Optical System Design: Keeping the Coatings in Mind
JDSU
An optical coating engineer is frequently confronted with a difficult specification for a coating. Often the difficulty in the specification results from the particular form of the optical system. If...
Ultraviolet Reflectance Imaging: Applications
Dr. Austin Richards, Oculus Photonics
Reflected-ultraviolet imaging is a rather mysterious area of the imaging field. There is relatively little actual UV imagery to be found on the Internet or in the literature compared to near-infrared...
Beryllium Mirrors: Refinements Enable New Applications
Vladimir Vudler and Peter Richard, Hardric Laboratories, Inc.
With a specific gravity of 1.85 g/cm3, beryllium is the lightest metal that is workable. It is 45 percent lighter than aluminum and approximately five times as stiff. Its stiffness to weight ratio...
Beamsplitters: A Guide for Designers
CVI Melles Griot
Plate beamsplitters Plate beamsplitters consist of a thin plate of optical crown glass with a different type of coating deposited on each side. The first surface is coated with an all-dielectric...
Optical Components: Finding Your Way Through the Maze
CVI Melles Griot
Lenses come in a variety of shapes, sizes and materials. They can be made of a single piece of glass or have multiple elements; their surfaces can be spherical, aspheric or cylindrical; they can be...
Beam Diagnostics: Meeting the Need for High Quality
Coherent, Inc.
For any discussion of laser beam diagnostics, it is first necessary to define some terms that characterize beam properties. Broad definitions can include measurements of laser energy or power,...
