Custom Precision Optical Components

Optical prisms are precision optical components for beam turning, image rotation, light splitting and spectral analysis. Hong Kong Felix Glass Co., Limited customizes high-precision prisms in H-K9L, fused silica, sapphire and IR substrates with AR, aluminum & silver reflective coatings, full OEM & ODM service for machine vision, spectroscopy, medical optics and laser positioning systems.

Felix Glass provides custom precision infrared optics including ZnSe, ZnS, germanium optical windows and lenses for CO₂ laser, thermal imaging, defense EO/IR and industrial detection systems. We support prototype and mass production with professional AR, BBAR, DLC coating services.

Felix Glass produces fully custom precision optical domes with sapphire, fused silica quartz and BK7 optical glass materials, including hemispherical and hyper-hemispherical profiles for deep-sea ROV, aerospace defense sensors, automotive LiDAR, underwater surveillance cameras and industrial optical detection systems. Available Material Tolerance Reference 1. BK7 Optical Glass: Standard dimensional & surface precision for cost-sensitive indoor vision equipment 2. Fused Silica / Quartz: Low thermal expansion, tight UV transmission tolerance for high-temperature scenarios 3. Sapphire Al₂O₃: Ultra-tight ultra-precision tolerance, maximum hardness & deep-water pressure resistance for long-term harsh environment service Dome Geometry & Application Difference 1. Hemispherical Optical Dome: Standard 1:2 radius-wall thickness ratio, balanced pressure resistance & optical performance, mainstream for regular underwater imaging cameras 2. Hyper-Hemispherical Optical Dome: Extended spherical surface, wider field of view, designed for wide-angle LiDAR scanning & large-range underwater detection 3. Custom Asymmetric Domes: Custom flange, O-ring sealing groove, chamfer and edge steps machined strictly per customer engineering drawings Engineering Performance Constraints Optical transmittance, imaging aberration and maximum pressure resistance are determined by dome material, wall thickness, spherical curvature and custom thin-film coating. All final mechanical and optical specifications will be fully confirmed during free pre-production DFM engineering review. Full In-House Precision Optical Dome Manufacturing Process Raw blank cutting → CNC spherical rough turning → multi-stage ultra-fine polishing → custom edge sealing machining → dust-free ultrasonic cleaning → customized AR multi-band vacuum coating → interferometer & spectrometer FQC testing → Class 10000 dust-free vacuum packaging.
