Precision Molded Aspherical Lenses

Product Information

Precision molding enables the mass production of aspherical lenses. These high performance aspherical lenses are often used in optical elements which eliminate monochromatic aberrations (e.g. spherical aberration) and hence lead to a better overall image quality. In addition, aspherical lenses can be used to replace a multi-spherical element assembly, which leads to overall weight reduction and therefore a more compact design.

Benefits

Due to the unique advantages associated with the use of aspherical lenses, the overall lens system has improved quality as well as reduced weight and size. Other benefits include: Strong consultative support from application team Customized lenses produced according to customers' requirements High accuracy because of reduction in weight and a more compact design Improved collimating accuracy

Key Applications

Aspherical lenses are suited for use in both industrial and consumer optics: Industrial Optics: Binoculars Microscopy (eye-piece lenses for microscopes) Sports Optics (rifle sight) Sensors Consumer Optics: Digital Projection Digital Single Lens Reflex Cameras (DSLR) Digital Still Cameras (DSC) Camcorders

Materials Used

Optical glass ZERODUR® glass ceramic Fused silica LITHOSIL®

Forms of Supply

Standard forms of supply are as follows: Lens diameter: 10 – 35 mm Lens thickness: 3 – 10 mm Radii / pole radii CC: 20 – 250 mm Radii / pole radii CX: 20 – 250 mm In addition, our experienced application team looks forward to supporting our customers in terms of developing customized moldable aspherical lens designs. Please contact us for further information.

Specifications

Diameter tolerance: h8 Form error: ≤ 5 fringes (sph. side)* Form error: ≤ 5 ¥ìm PV (asph. side)* Irregularity: ≤ 2 fringes (sph. side)* Tilt: ≤ 2´ Surface roughness: < 3 nm rms * Values depend strongly on lens geometry and glass type.

Quality Assurance

Our quality control is based on statistical process control, as well as on a rigorous final inspection. Measuring instruments used include 2D and 3D aspheric profile measurement systems, an interferometer, and an atomic force microscope.
