Optical Dome
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, and domes ideally change nothing. Typically the lead element in an optical system, a dome is often exposed to the environment to resist wind & rain erosion for pyrometers, and as high-pressure viewports in underwater cameras and submersibles.
Optical domes are lenses with two concentric spherical surfaces. Sometimes they are 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 optical domes are high-quality optical products that are produced through precision polishing. They ensure clear, distortion-free protection for your camera objective or other sensitive equipment.

Common materials for optical domes are H-K9L, equivalent N-BK7, N-BK10, N-K5, fused silica, and Silicon:
-H-K9L, N-BK7, N-BK10, and N-K5
They have similar characteristics, a relatively hard material, with excellent chemical durability, and wider transmission. These characteristics make them very suitable protection for Pyronometers' thermoelectric detectors.
-K9L and N-BK7
With excellent mechanical and chemical properties, also offer excellent transmission from 300nm up to 2µm, with very few bubbles and inclusions, making them perfect for high-performance visible applications. The thicker optical dome is ideal for underwater applications such as ROV, pipeline detection, and underwater probing and is widely used in the marine sector, underwater oil exploration, etc. The thicker optical dome is also suitable for underwater applications such as underwater robotics, pipeline detection, and underwater exploration, and is widely used in the marine sector and underwater oil exploration.
-Fused Silica
With excellent mechanical and chemical properties, UV quartz has high transmission at 200-400nm and IR quartz has excellent transmission from UV to NIR 3600nm. They are a good choice for high-quality Pyranometers, and UV Radiometers, and UV fused silica is also a common choice for underwater applications.
-Silicon
With good transmission in the IR, is used for Pyrgeometers.
