Meller Optics Inc.Request Info
Meller Optics Inc.’s sapphire and spinel optical domes provide front-surface protection to electronic sensors and detectors in harsh aerospace and industrial environments. They feature 160° maximum included angles to extend the viewing angles of cameras, sensors, detectors and other devices, and they provide extreme physical protection in harsh environments. Able to withstand moving sand, dirt, water and chemicals, they can be custom-engineered with precise edge steps and profiles for mounting purposes. They provide up to 85% transmission uncoated in the ultraviolet to infrared, with up to 99% when antireflection-coated on two sides. They exhibit Moh 9 hardness (second only to diamond) and can be supplied with outer-diameter sizes of up to 101.6 mm, with surface finishes to 20-10 scratch-dig.

A light-tight box that receives light from an object or scene and focuses it to form an image on a light-sensitive material or a detector. The camera generally contains a lens of variable aperture and a shutter of variable speed to precisely control the exposure. In an electronic imaging system, the camera does not use chemical means to store the image, but takes advantage of the sensitivity of various detectors to different bands of the electromagnetic spectrum. These sensors are transducers...
1. A device designed to convert the energy of incident radiation into another form for the determination of the presence of the radiation. The device may function by electrical, photographic or visual means. 2. A device that provides an electric output that is a useful measure of the radiation that is incident on the device.
