The performance calculations performed during the design of an optical coating normally involve ideal conditions. The light is precisely collimated and monochromatic and the layers have precise thicknesses and optical constants. Then a subsequent performance measurement of a manufactured coating will involve illumination with finite aperture and bandwidth. When the coating is finally used in an optical system, it will be subject to illumination and environment that are less well controlled, and will also exhibit departures from perfection including layer thickness errors, lack of uniformity and the like. Oblique incidence brings special problems, including spectral shifts, performance distortion, polarization and relative retardation. The effects can sometimes be surprising but they are not mysterious and can be readily predicted according to Angus Macleod of the Thin Film Center Inc (Tucson, AZ) who explains in this live Web event that in order to deal effectively with such effects they must be understood.

Deposition Sciences, Inc. (DSI) :

Deposition Sciences produces the most durable optical thin film coatings in the industry, including advanced technology multispectral filters for demanding imaging and applied optics applications.  DSI is the expert in applying optical thin film coatings evenly to various substrates, including plastics, complex shapes and a variety of sizes. This ability is becoming increasingly critical to meet higher performance standards and durability requirements for defense and industry.


Coating capabilities range from the ultraviolet through the visible, near-infrared, midwave-infrared and out to the longwave- infrared.  Deposition Sciences provides thin film filters for applications such as telecommunications, imaging, aerospace, military and defense, commercial lighting, information display, solar simulation, material aging, biomedical and life sciences.


DSI’s patented MicroDyn® reactive sputtering technology enables superior multilayer thin film coatings for optics and other thin film technologies.  For multispectral filters, DSI’s physical vapor deposition technology is used when multiple filters are required on a single substrate. Standard coatings and/or custom solutions are also available to meet your specific requirements.
