SCHOTT AG - Cylindrical Lenses

Cylindrical Lenses

Product Information

Cylindrical lenses have a spherical radius in one direction only. For over 30 years, SCHOTT Advanced Optics has been producing cylindrical lenses supported by the ability to machine a large variety of custom-made lenses in different sizes with very tight curvature tolerances, as well as small thicknesses. In addition, we also offer high quality in-house coating capabilities.

Benefits

Our development of a special technique allows us to machine lenses with convex radii ranging from 1 mm to 10 mm.

With our long experience in the production of cylindrical lenses, we:

Have a large quantity of tools available for manufacturing lenses of different radii
Have the expertise in machining difficult glass types
Can maintain close curvature tolerance despite small thickness
Can achieve high precision radii
Can center in the order of 2 minutes on small rectangular lenses

Key Applications

Cylindrical lenses are widely used, but not limited to the below applications:

Laser projection
Bar code scanning
Holography
Optical information processing and computing
Medical applications
Anorphometer (cinema 16/9)
Stretching a point of light into a line

Materials Used

All types of optical materials can be used, including:

Optical glass

ZERODUR^® glass ceramic

Fused silica LITHOSIL^®

Forms of Supply

Lenses can be supplied in 3 forms, namely, coated lenses, uncoated lenses or semi-finished (grinded) lenses.

Specifications

We can produce cylindrical lenses according to DIN 10110, DIN 3140, or MIL-specs. We can also manufacture customized cylindrical lenses according to customers’ drawings.

Convex radius from 1 mm to 3000 mm

Special technique for convex radii from 1 mm to 10mm

General precision 0.1 % of radius

Concave radius from 10 mm to 3000 mm

Surface quality: λ/2 over 100 mm in the direction parallel to the cylinder axis

Up to 2 λ over 100 mm in the direction perpendicular to the cylinder axis

Fitting error: defined in consultation with our engineers

Surface defects: defined in consultation with our engineers

Micro roughness: standard 5 nm Rq to 2 nm Rq, depending on surface dimensions and material

Quality Assurance

Our quality control is based on self-checking during production and 100% final inspection. Measuring instruments used include 2D profile measurement (0.2 µm accuracy) and 3D holographic interferometer measurement (λ/2 accuracy). An optional profilometry test (0.1 µm accuracy) is also available.
