Drawing and application review
We read the drawing against the optical function, flag ambiguous datums or tolerances and identify the parameters that drive cost or risk.
TradeOPC is based in Shangrao and works with qualified local optical fabrication, coating and metrology partners. We select the route by process and requirement, then hold the technical thread from drawing review to release.
The public boundary is deliberate: standard ranges are shown as guidance, drawing-review work is identified separately, and anything outside the launch scope is stated rather than implied.
Send the drawing to the RFQ deskDifferent optical processes have different strengths. Rather than force every part through one line, we match the route to the drawing and keep the assumptions, changes and acceptance criteria in one place.
Every project starts with the same discipline: define the requirement, close the gaps, then choose the route.
We read the drawing against the optical function, flag ambiguous datums or tolerances and identify the parameters that drive cost or risk.
Substrate, wavelength band, AOI, polarization and environmental exposure are checked before a coating route is proposed.
Fabrication, coating and measurement steps are matched to the part. The inspection method and documentation are agreed with the quotation.
Production follows the approved baseline. Any drawing, coating or acceptance change is recorded before it affects the order.
This matrix is a conversation tool, not a guarantee. Final feasibility depends on the complete drawing, substrate, coating curve, quantity and inspection plan.
| Family | Standard starting point | By drawing review | Not in launch scope |
|---|---|---|---|
| Lenses | Ø2–150 mm; N-BK7 / H-K9L; λ/2; 40/20 | Ø150–300 mm; UV fused silica or sapphire; λ/4–λ/10; 20/10–10/5 | Molded consumer optics and active lens modules |
| Prisms | Catalog-scale geometry; ±3 arcmin; 60/40 | Larger or custom geometry; ±5 arcsec; 40/20 or 20/10 | Complex active prism assemblies |
| Filters | Standard spectral bands; 40/20 | Custom CWL, FWHM, blocking and hardened stacks | Active tunable filters |
| Mirrors | λ/4; 40/20; protected aluminum or dielectric HR | λ/8–λ/10; custom AOI, band and laser-damage review | Large adaptive or actively cooled mirrors |
| Reticles | Pattern review from vector data; BK7 or UV fused silica | Custom line width, chrome thickness and pattern inspection | Semiconductor mask writing |
| Gratings | Concave or ruled format reviewed with the optical design | Custom groove density, blaze wavelength and efficiency target | Volume holographic master production |
| Coatings | AR and HR bands reviewed from a spectral target | Custom multilayer stacks, masking and durability plan | In-line coating inside a customer cleanroom |
Dimensions, tolerances, reflectance, transmission and inspection values are examples only. The approved drawing and quotation define the delivered requirement.
Inspection is not a generic checklist. The drawing and application determine which measurements matter, how they are reported and what evidence travels with the parts.
A product name alone does not define an optical part. The following inputs let us respond with a scoped route rather than a generic price.
Share the optical requirement, coating target and inspection expectation. We will return a scoped technical route.
