Description

Optical dome is composed of two parallel optical surfaces. Among optics domes are unique because, unlike any other optical components, the key attribute of the dome is to have no optical effect. Mirrors reflect light, lenses bend light, domes ideally change nothing. Typically the lead element in an optical system, a dome is often exposed to the environment. Dome lens due to their ability to withstand wind and rain erosion.

Optical domes are lenses with two concentric spherical surfaces. Sometimes they are being referred to as bent plan parallel plates. Consequently it is customary to define parallelism between two surfaces as the maximum thickness variation between the two surfaces. In perfect domes the convex radius is equal to the sum of the dome thickness and concave radius. Slight departures from that rule are sometimes desired.

These protection covers are high quality optical products which are produced through precision polishing. They ensure clear, distortion free protection for your camera objective or other sensitive equipment.
