Precision optical manufacturing requires strict control of materials, dimensions, surface quality and optical performance.
Chenyu Optics manufactures customized optical components using various optical materials, including optical glass, fused silica, sapphire and infrared materials.
Our manufacturing workflow covers precision machining, optical polishing, coating integration and inspection to ensure consistent optical performance.

Custom optical components manufactured according to customer drawings with controlled dimensions, geometry and tolerances.

Precision grinding and polishing processes provide controlled surface quality, flatness and optical performance.

Optical coatings including AR, HR, BBAR and DLC coatings are available according to wavelength requirements.

Dimensional inspection and optical testing ensure products meet customer specifications before shipment.
A controlled workflow supports traceability and consistent execution from incoming material through final packaging.
Materials are selected according to wavelength, environment and application requirements.
Raw materials are processed into controlled dimensions.
Geometry and thickness are gradually established.
Optical surfaces are polished to the specified figure, flatness, surface quality and roughness. Review our Optical Polishing capability.
Specified coatings are applied for transmission, reflection or environmental protection. See Optical Coating.
Dimensions, surface condition, figure and spectral performance are verified according to the drawing. See Optical Metrology Inspection.
Finished optics are cleaned, visually checked and protected for shipment using packaging selected for the component and coating.
This section demonstrates Chenyu Optics' manufacturing environment, processing facilities and quality control capability for customized optical components.




Suitable for visible, infrared and laser optical applications.
Capabilities are evaluated against component geometry, material and project-specific inspection requirements.
| Capability Item | Routine Capability | Requirements Requiring Separate Evaluation |
|---|---|---|
| Materials & Component Types | Optical glass, fused silica, sapphire, CaF₂, BaF₂, ZnSe, ZnS, germanium and silicon; windows, lenses, prisms, mirrors, filters and infrared optical components. | Unlisted materials, unusual material grades, assemblies or geometries require material and process review. |
| Processing Size Range | Drawing-defined for round, rectangular and custom-shaped parts. | Minimum/maximum size, extreme aspect ratios, large apertures and very thin parts require evaluation by material, geometry and tolerances. |
| Dimensional Tolerance | Controlled according to the approved drawing using dimensional inspection appropriate to the geometry. | Tight tolerances are evaluated together with component size, thickness, shape, material and measurement method. |
| Surface Quality | 60-40, 40-20, 20-10 and 10-5 scratch-dig options, depending on component requirements. | Laser-grade or other special cosmetic requirements require review of material, clear aperture, coating and inspection standard. |
| Surface Figure / Flatness | λ/4, λ/8 and λ/10 options, specified at the agreed reference wavelength and over the defined clear aperture. | More demanding figure, unusual apertures, large parts, non-flat geometries or special test wavelengths require interferometric feasibility review. |
| Parallelism & Surface Roughness | Drawing-defined parallelism and nanometer-level surface-finish options, dependent on material and geometry. | Arc-minute/sub-arc-minute requirements or sub-nanometer finish must be evaluated with the measurement method and usable aperture. |
| Coating Capability | AR, BBAR, HR, metallic and DLC coating options from UV through visible, NIR and IR, subject to substrate compatibility. | Laser-line, high-power, multispectral, steep-edge or environmental durability requirements require coating design review. |
| Inspection Equipment / Methods | Dimensional instruments, surface inspection microscope, interferometric surface-figure testing, parallelism measurement, surface roughness testing and spectrophotometric T/R measurement as applicable. | Customer-specified equipment, sampling plans, environmental tests or third-party testing require prior agreement. |
| Inspection Documents | Dimensional reports, surface-quality records, coating test reports, optical measurement data and final inspection reports can be provided when agreed. | Full traceability packages, special report formats, raw data, certificates or third-party reports require definition before quotation. |
