Description

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. Generally a dome is often exposed to the environment. Accordingly, domes made from hard ceramic materials are preferred due to their ability to withstand wind and rain erosion.
Considering PMMA material dome lens has a better price and not fragile, many customers choose acrylic dome lens, the picture shown is a PMMA dome lens with flange, which is for a CCTV camera lens protection, CCTV camera dome lens.

Domes make it better - Dome lens help correct aberrations that occur when light travels thru water as opposed to air. Domes can deliver better results compared to flat ports, and also make it easier or possible some results that flat ports would not capture.

● Size matters
Bigger domes are better than smaller domes, for a number of reasons. The tradeoffs are; heavier, bulkier, pricier than smaller domes.

● Glass is optically superior
