| | .jpg) | A viewport, sometimes referred to as a window, is an optical component that provides a means for visual, optical or broad-band energy transmission in and out of a vacuum system.
There are two types of viewports offered, zero-length and tubulated. A zero-length viewport has a thickness no larger than that of its mounting flange. This makes it easier to protect from accidental damage as there are no parts protruding from the mounting flange. It also allows for the best angle of view.
Ceramaseal's precision-engineered standard viewports and extended range viewports are available in a variety of viewport materials: Sapphire, Fused Silica, BK7, Zinc Selenide, Cleartran™, Magnesium Fluoride, and Calcium Fluoride. Other viewport materials are available upon request. As its name suggests, an extended range transmission port is an optical component that provides for transmission of radiation in either the ultra violet or infrared portion of the electromagnetic spectrum. Standard viewports made of either fused silica or sapphire have useful transmission from .25 microns to 2.5 or 4.0 microns respectively. Extended range window materials have a combined transmission range from .12 microns to 20.0 microns. | |
