Product Detail

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.
