High-Precision Large-Diameter Visible Lenses from China Suppliers | ALHAZEN Factory 100–500mm for Telecentric & Astronomical Applications
●Product Description
Technical Features
- Large Aperture Lenses with diameters of 100–500mm, surpassing the conventional 10–100mm range.
- High Precision Low-dispersion materials (e.g., CaF₂), surface accuracy λ/4 (@632.8nm), roughness <1nm.
- Anti-Reflective Coating Transmission rate >99% (central wavelength), adaptable to multi-scenario optical designs.
Applications
- Telecentric Lenses Eliminate perspective errors in industrial inspection.
- Astronomical Observation Enhance light-gathering capacity and resolution for deep-space telescopes.
- High-Power Laser Systems Enable large-aperture energy transmission and uniform distribution.
Mass Production
- Scalable Delivery Automated production lines support monthly output of thousands, tolerance ±0.1mm.
- Customization Aspheric/freeform surface designs and extended spectral coatings.
●Differentiation Highlights
Integrated Technology
Diffractive optics (DOE) and freeform surfaces optimize field curvature and chromatic aberration.
Full-Process Validation
MTF test reports and ISO 10110 drawings ensure traceable optical performance.
