Aspherical Lenses 

Avantier designs and manufactures precision aspherical lenses for advanced optical applications across industries including:
  • Manufacturing
  • Aerospace and defense
  • Medical and life sciences
  • Scientific instrumentation
  • Consumer electronics
Aspheric lenses feature non-spherical surface profiles that correct optical aberrations more effectively than traditional spherical optics. This allows for sharper imaging, reduced distortion, and compact, lightweight optical assemblies.

Key Types of Aspheric Lenses

Avantier offers a wide range of high-performance aspheric lens solutions:

Factory Standard (Manufacturing Capability)

Avantier’s in-house production delivers exceptional surface precision and quality across a wide range of specifications:

Diameter Tolerance+0/-0.100mm – +0/-0.010mm
Asphere Figure Error (P – V)3μm – smaller than 0.06μm
Vertex Radius (Asphere)±0.5% – ±0.05%
Sag25mm max
Typical Slope Error1μm – 0.15μm per 1mm window
Centering (Beam Deviation)3 arcmin – 0.5 arcmin
Center Thickness Tolerance±0.100mm – ±0.010mm
Surface Quality (Scratch Dig)80-50, 40-20,10-5
Aspheric Surface MetrologyProfilometry (2D & 3D) & Interferometry

Custom Aspheric Lenses

Avantier’s optical engineering team partners with clients to develop custom aspheric lenses that meet critical project requirements:

  • Optical glass, fused silica, germanium, and plastic materials
  • Diameters from sub-millimeter up to 200+ mm
  • Diamond turning, CNC polishing, and precision molding
  • Fully customizable AR, HR, IR, UV coatings

Used across applications such as:

  • Biomedical and life sciences
  • Aerospace and defense imaging
  • High-power laser systems
  • Semiconductor and industrial metrology
  • Optical sensors and consumer electronics

Aspherical Lenses Material Selection

The choice of materials for aspherical lenses is influenced by factors such as wavelength requirements and manufacturing cost. The following summarizes materials compatible with each manufacturing process.

Optical Advantages of Aspheric Lenses

Spherical Aberration Correction – Aspheric lenses are expertly engineered to direct all incoming light rays to a single focal point, eliminating spherical aberration. This enhances image sharpness, minimizes blur, and ensures optimal focus across the field—making them ideal for high-precision imaging systems, laser collimation, and optical instrumentation.
Figure 1. Aspherical Lens (left) vs Spherical Lens (right)

Aspheric vs. High-Index and Pancake Lenses – While high-index lenses use material properties to improve light bending, aspheric lenses optimize surface geometry for superior aberration correction. Compared to compact pancake lenses, aspheric lenses deliver significantly better edge-to-edge image clarity and reduced distortion.

Advanced Surface Geometry & Freeform Capabilities – Avantier supports both rotationally symmetric and freeform aspheric designs. These profiles feature curvature that varies with radial distance from the optical axis, offering greater flexibility in correcting complex aberrations. Key surface profile metrics include:

  • Qbfs – RMS slope departure from a best-fit sphere
  • Qcon – Sag departure from a base conic

Structure of an Aspheric Lens

Aspheric lenses are optical elements with a radially varying curvature, allowing them to correct aberrations more effectively than spherical lenses. Unlike traditional lenses with uniform curvature, aspheric surfaces are designed to bring light to a sharper, more precise focus.

These lenses are widely used in:

  • Automotive sensors
  • LED optics
  • Medical imaging
  • High-resolution cameras
  • Laser systems

The surface of a rotationally symmetric asphere is mathematically defined using a sag equation:

Where:

  • Z: sag of surface parallel to the optical axis
  • s: radial distance from the optical axis
  • C: curvature, inverse of radius
  • k: conic constant
  • A4, A6, …: 4th, 6th, … order aspheric coefficients

When all coefficients are zero, the surface is a standard conic shape—elliptical, parabolic, or hyperbolic, depending on the value of k.

Spherical vs. Aspheric Performance Comparison

As shown in the chart below, a 25 mm f/1 spherical lens produces significantly larger spot sizes compared to an equivalent aspheric lens:

Avantier measures and controls all critical aspects of surface accuracy:

  • Form Error – Large-scale deviations, RMS or peak-to-valley
  • Waviness – Mid-frequency undulations (slope error)
  • Surface Roughness – High-frequency texture, relevant for scatter & laser performance
  • Radius Error – Curvature deviation corrected by focus tuning
