Optical glass lenses are core imaging and beam-control elements for visible/near-IR systems, with high transmission, precision, low dispersion, and stable physical/chemical properties. Applications include security imaging, industrial lasers, scientific instruments, medical optics, and consumer electronics. Scysgx uses 260 precision-processing machines and 65 specialist inspection instruments for blank cutting, milling/grinding, polishing, centering/edging, coating, and inspection. Customized spherical/aspheric, plano-convex, biconvex, plano-concave, and other designs span 1–500mm with surface accuracy up toλ/10. Antireflection, high-reflection, and beamsplitting coatings provide precise, stable solutions for varied optical systems.

Broadband high transmission over 350nm–2500nm from visible to near-IR, with excellent uncoated-substrate transmission and further improvement after coating. Ultralow-dispersion imaging: precise refractive-index matching and suitable Abbe number provide excellent chromatic correction and clear, distortion-free images. Ultraprecision fabrication: dimensional tolerance ±0.01mm, surface figure to λ/10, centration ≤±1′ and surface quality 60/40. Full structural customization: spherical, aspheric, plano-convex, biconvex, plano-concave, biconcave and meniscus designs. Strong environmental stability: low expansion, acid/alkali resistance and resistance to deliquescence for harsh industrial, medical and outdoor use. All-application coating compatibility: AR, HR, filters, polarization, beam splitting and high-laser-damage-threshold coatings. IV. Core material advantages. Spectral: high broadband transmission over 350nm (UV)–2500nm (near-IR), without significant absorption/scattering. Optical: refractive index nd≈1.459, Abbe number suited to precision imaging, uniform dispersion and easily corrected aberrations. Thermal: low expansion maintains optical stability under temperature fluctuations, without thermally induced focus shifts. Mechanical: moderate hardness and easy precision polishing achieve nanometer surface finish. Chemical: humidity, acid/alkali and aging resistance for long-term performance without degradation. V. Structures. Spherical: plano-convex, biconvex, plano-concave, biconcave and meniscus lenses. Aspherical: precision designs correct spherical aberration and improve imaging. Functional: collimating, focusing, imaging and cemented achromatic lenses. VI. Standard coatings. Visible AR: 0.4–0.7μm reduces reflection losses and improves brightness. Near-IR AR: dedicated 1.05–1.58μm for infrared lasers/imaging. HR: specified-band reflectance for beam turning and laser resonators. Special coatings: filtering, polarization, beam splitting and high laser-damage threshold for multifunction use. VIII. Yasi Optical advantages. Fully controlled in-house closed-loop cutting → milling/grinding → polishing → centering/edge grinding → coating → inspection, without outsourcing and with full traceability.
