134mm Hemispherical Quartz Glass Dome Lens

      134mm Hemispherical Quartz Glass Dome Lens

      The dome lens we pffer is an optical window composed of two parallel curved surfaces. Dome lenses are commonly used in defence applications and often in extreme environments such as submersible ROVs. For this reason our dome offer both high transmission as well as durability. Other application for our dome include visible-range domes for pyranometers and infrared-range domes for pyrgeometers, and as high pressure viewports in underwater cameras and submersibles.

Example with BK7 material：These N-BK7 Meniscus lens are available uncoated or with one of five antireflection coatings (-A, -AB, -B, -C, or -D), which reduces the amount of light reflected from each surface of the lens (see the Selection Guide table below for coating option). Since approximately 4% of the incident light is reflected at each surface of an uncoated substrate, the application of an AR coating improves transmission, which is important in low-light applications, and prevents the undesirable effects (e.g., ghost images) associated with multiple reflections. Having optics that are AR coated on both surfaces is particularly desirable for applications utilizing multiple optical elements. Please see the Graphs tab for additional coating information.
