Window

Window

With advanced single/double-surface polishing machines, Spectro Optics offers flexible solutions: cost-effective bulk-produced protective windows and custom ultra-high-precision windows up to 600.0 mm, covering transmission applications from Deep Ultraviolet (DUV) to Far Infrared (FIR). 

 

Our core production ensures exceptional precision: asphalt-plate single-surface polishing and multi-stage grinding-polishing deliver stable flatness of 1/10λ and surface roughness as low as 2 nm, minimizing light scattering. We provide Anti-Reflective, hydrophobic anti-fouling, ITO conductive coatings, plus metal ring encapsulation for enhanced durability in harsh conditions. 

 

We process Silicon (Si), ZnSe, ZnS, germanium (Ge), fused silica, sapphire, and more—sapphire and fused silica windows are camera favorites for superior hardness and transmittance. Rigorous quality control includes real-time flatness monitoring via laser interferometers and surface roughness checks with white light interferometers, plus final tests for dimensional accuracy (±0.01mm), parallelism (≤5 arcsec), VIS-range transmittance (≥99.5%), and environmental reliability. 

 

Our optical windows excel in full-band transmission and stability, serving industrial inspection, infrared imaging, laser systems, medical equipment, aerospace, consumer electronics, and beyond—delivering clear, stable optical channels for high-precision devices.

Mirror

Mirror

At Spectro Optics, our precision high reflection mirrors deliver exceptional reflectivity, ultra-low light loss, and unrivaled surface accuracy for the most demanding optical systems. Crafted from premium substrates like BK7 glass and fused silica, each mirror undergoes meticulous polishing to achieve nanometer-level surface smoothness and strict flatness tolerances, minimizing scattering, absorption, and beam distortion.


Our mirrors are manufactured using OPTORUN coating machines, integrated with advanced RF ion sources. These enable high-ion-current-density ion beam assisted deposition (IAD), ensuring dense, uniform, and adherent multilayer dielectric coatings. This advanced process achieves reflectivity exceeding 99.9% across UV, visible, and near-infrared spectra, with customized designs available for specific laser lines and incident angles.


Quality control is validated by Agilent Cary UV-Vis-NIR spectrophotometers, which verify precise spectral performance and consistent reflectivity. Our mirrors feature outstanding thermal stability, a high laser damage threshold, and superior environmental durability, ensuring reliable long-term operation. We offer custom sizes, shapes, and coatings to meet diverse industrial and laboratory applications, including laser resonators, beam steering, interferometry, and optical metrology.

Prism

Prism

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.
