In a typical evaporative coating chamber, one or more racks hold the substrate material to be coated. The first step in the process is to pump all the air out of the chamber to achieve a very high vacuum (10-6 Torr or better). A succession of coating materials is then evaporated, typically using either resistive heating or electron beam bombardment. Read more...

Sunshade, a thermal control material are utilized on satellite radar domes (radomes) to reject incident solar heat radiation while simultaneously allowing radio frequencies to pass unattenuated. This passively protects satellite electronics from being overheated by the sun without compromising transceiver bandwidth. Read more...

Edge filters, also sometimes called dichroic filters, are coatings that include long wave pass and short wave pass filters. These coatings transmit one range of wavelengths while blocking others. However, they are distinct from bandpass and notch filters in that they either pass wavelengths above (long wave pass) or below (short wave pass) a given single wavelength value. Read more...

Notch filters block a range of wavelengths while transmitting both shorter and longer wavelengths outside of the blocked region. Thus, they provide the exact opposite functionality of a bandpass filter. One of the most common uses of DSI notch filters is in thermal infrared imaging systems. Read more...

PRODUCT OVERVIEW

Fiber rod lenses are full cylindrical lenses. They are used to perform collimation and coupling in one axis only, and are particularly useful with sources having asymmetrical output, such as diode lasers. Both are widely employed in telecommunications and medical applications.

AR coatings are the most extensively employed type of optical thin film. By reducing the amount of light reflected from a surface, they improve system throughput, increase contrast, and enhance signal-to-noise ratio in virtually every type of optical system. Read more...

PRODUCT OVERVIEW

Micro Optic (full spherical) lenses are inexpensive, mechanically compact optical components used for collimating the output of optical fibers or diode lasers; they can also be used in pairs for fiber-to-fiber, diode-to-fiber and fiber-to-detector coupling, particularly when access to the collimated beam between the two balls is required. Widely employed in teleco... Read more...

Product Overview

Uniform coatings on highly curved optical components, such as tubes, cylinders, and domes, are inherently challenging to achieve in most thin film deposition processes. In typical line-of-sight deposition processes, such as evaporation and sputtering, curved parts become more thickly coated at their centers and thinner at their edges. Continuous rotation is...
