 Available Services 

  • Custom Aspheric Machining 

    Single-point diamond turning and ultra-precision polishing. We fabricate custom aspheric curves, diameters, focal lengths and edge chamfers strictly per your optical drawings.

  • Custom Anti-Reflection Coatings 

    Tailored AR coatings for visible, near-infrared, UV and laser wavelengths. Multi-layer broadband coatings can be customized for your target spectrum.

  • Optical Metrology & Technical Support 

    Every lens is tested by interferometer and profilometer for surface figure, centration and surface quality. Our optical team provides design review and system matching consultation.

Key Differentiators 

Precision Aspheric Lenses adopt mathematically optimized non-spherical surface profiles. Different from standard spherical lenses, a single aspheric element corrects spherical aberration effectively. It replaces multi-piece spherical lens groups, simplifying optical structure, lowering overall weight, improving focusing spot quality and resolution for compact high-performance optical systems.

Why Choose Precision Aspheric Lenses 

  • Single-Element Aberration Correction 

    The optimized aspheric surface eliminates spherical aberration in one component. Light rays converge uniformly to the focal plane for sharp imaging and tight laser focusing with low distortion.

  • Miniaturized Optical Design 

    One aspheric lens substitutes multiple spherical lenses. It reduces component count, assembly difficulty, module size and weight for space-constrained optical equipment.

  • Broadband Material & Coating Options 

    Available in optical glass, fused silica, IR crystals and other substrates. Custom AR coatings cover UV, VIS, NIR and laser wavebands to match your light source and sensor.

Applications 

Precision Aspheric Lenses are widely used in laser collimation and beam shaping, high-resolution machine vision, 3D scanning, medical endoscopy, biometric recognition, LiDAR, drone optical modules and spectral measurement instruments. They are ideal for compact optical systems requiring diffraction-limited focusing and high image clarity.
