Hemispherical Optical Dome
Description:
-
A hemispherical optical dome is a precision concentric spherical optical window with crown height equal to its radius, providing a symmetrical 180° field of view. Unlike super hemisphere domes with taller spherical crowns, standard hemisphere domes strike a good balance of cost, optical stability and mechanical protection, making them mainstream protective optics for medium and high-precision optoelectronic devices.
Parameter Specification Material Optical Glasses, Fused Silica, Sapphire, Infrared Material, etc. Diameter 8~350mm Diameter Tolerance ±0.1mm Wall Thickness 2~30mm Thickness Tolerance ±0.05mm Height 5~150mm Height Tolerance ±0.05mm Surface quality 40/20 Optical Dome Materials & Application Scenarios
- Visible Light Band: BK7 / H-K9L Optical Glass, Borofloat 33 Cost-effective with excellent homogeneity, ideal for surveillance cameras and industrial machine vision.
- UV & High-Temp Scenarios: Fused Silica (JGS1 / Corning 7980) Low thermal expansion and superior UV transmittance for meteorological instruments and UV detection systems.
- Mid-Infrared Thermal Imaging: ZnSe, ZnS High infrared transmittance, tailored for thermal cameras and infrared optical sensors.
- High Hardness & Corrosion Resistance: Sapphire Outstanding scratch resistance and long service life, suitable for marine, underwater and outdoor optical equipment.
Machined with dual concentric ultra-precision polished surfaces and tight concentricity tolerance, it reduces refraction shift and suppresses distortion throughout the full 180° viewing angle. Our hemisphere domes are extensively used in civil aerospace, underwater robots, automotive LiDAR, machine vision, panoramic surveillance and meteorological monitoring, featuring steady light transmission and robust resistance to moisture, high pressure, dust and temperature changes.
