Precision flat optics manufactured to optical-laboratory tolerances, with in-house coating and full inspection at every stage.
Standard production covers the requirements of most medical, laser, and industrial applications. High-precision tolerances are available on request, with separate quotation and lead time.
| Capability | Standard Production | High-Precision Option |
|---|---|---|
| Surface Flatness | λ/4 @ 633 nm | λ/10 @ 633 nm |
| Surface Quality (Scratch-Dig) | 60/40 | 20/10 |
| Parallelism | 30 arc-sec | 5 arc-sec |
| Diameter Range | 3 mm – 300 mm | 3 mm – 300 mm |
| Thickness Range | 0.5 mm – 20 mm | 0.5 mm – 20 mm |
For shapes outside our standard capability, we will refer your inquiry to a trusted partner rather than promise what we cannot deliver. Transparency over up-sell.
Unlike most small Chinese optics workshops that outsource coating, we operate two Optorun systems and two vacuum coating chambers on-site — giving us full control of lead times, quality consistency, and confidentiality of your design data.
Single-wavelength and broadband, custom-designed per substrate and spectral range.
Laser-line and broadband, with custom angles of incidence.
Symmetric (50:50) and asymmetric splitting ratios.
Custom cut-on / cut-off wavelengths for fluorescence, laser combining, and filtering.
Bandpass, longpass, and shortpass with custom center wavelengths and bandwidths.
Linear polarization coatings on custom substrates.
Fabrication, coating, and inspection operate within a 2,000 m² production campus in Qingdao Hi-Tech Zone.






Because coating performance depends on substrate, wavelength, angle of incidence, and damage-threshold requirements, we design each coating curve to match your application — not to a stock catalog. To request a coating quotation, please provide:
We return a coating design proposal and quotation within 48 hours.
