High-Precision Prism Production & Inspection Facilities

Spectro Optics is equipped with top-tier domestic manufacturing and precision inspection equipment, dedicated to custom optical prisms with accuracy up to 1 arcsecond.

We adopt a professional 2.0m ring polishing machine to achieve ultra-high flatness up to PV λ/20. A full range of precision processing tooling is in stock to ensure consistent angular accuracy across batches. Meanwhile, our high-precision CNC machining centers support custom special profile shaping, precision hole drilling and standardized ultra-fine chamfering for complex prism configurations.

Our seasoned optical engineers strictly control every processing parameter, including polishing abrasive grade, lapping plate pressure, rotational speed, temperature stability and workshop cleanliness, to eliminate surface defects and internal processing stress.

For metrology and quality verification, we are equipped with a 6-inch ZYGO laser interferometer to test surface flatness, beam distortion and wavefront error. We also deploy high-precision angle measuring instruments, optical profile projectors for dimensional tolerance and chamfer inspection, as well as LED cold light defect detection systems for strict surface quality assessment per international optical standards.
