PRODUCT DESCRIPTION

Optical Dome

Optical domes are lenses with two concentric spherical surfaces. Sometimes they are referred to as bent plane parallel plates. Consequently it is usual to define parallelism between two surfaces as the maximum thickness variation between the two surfaces. In perfect domes, the convex radius equals the sum of the dome thickness and concave radius. Optical domes are used for underwater photography, as a part of a protective case. Also they are as a part of sun tracking used in solar collectors.

Custom Optical Domes Applications

Underwater cameras and imaging: In deep-sea environments, they allow precision optical components to operate smoothly under high-pressure conditions. They prevent water from entering the optical system while providing a clear view for submersible ROVs and AUVs.

Defence: Infrared optical shields are vital for heat-seeking missiles, providing a wide range of viewing directions without beam deflection. Durable substrates such as sapphire or MgF2 perform well even under extreme conditions.

Weather monitoring: Used in weather monitoring systems to protect optics while enabling accurate measurements.

Navigation systems: Ensure accuracy and protection of navigation systems.

Head protection optics: for head protection while enabling optical functions.

Safety technology: for surveillance and monitoring purposes in safety systems.
