Lessons learned from the telecom industry have helped fuel efforts to produce smoother, lower-cost coatings for a variety of commercial applications.

Hank Hogan, Contributing Editor

Over the past few years, the need to pack more telecommunications channels into a given swath of optical spectrum has forced manufacturers to offer deposition equipment that produces less costly and more uniform optical coatings. Although the pace of technical innovation has slowed, it has not stopped. New developments promise even smoother and less expensive optical coatings, many of which are useful for a number of consumer applications in addition to telecommunications. A look at them reveals where deposition technology is headed and where possible solutions to various problems...Read full article

    optical coatings
    Optical coatings are thin layers of materials applied to optical components, such as lenses, mirrors, filters, and prisms, to modify their reflective and transmissive properties. These coatings are designed to enhance the performance of optical systems by controlling the way light interacts with the surfaces of the components. The primary purposes of optical coatings include: Antireflection coating: This type of coating is designed to reduce reflections from the surfaces of optical...
    optical spectrum
    1.) Generally, the electromagnetic spectrum within the wavelength region extending from the vacuum ultraviolet at 40 nm to the far-infrared at 1 mm. 2.) The wavelength or color distribution found in a white light source once passed through a grating, prism, or other dispersive optical element.
