Cylindrical Lenses

Cylindrical lenses focus or expand light in one dimension only. Common applications include laser line generation, anamorphic beam shaping, barcode scanning, sheet beam forming, and correcting astigmatism in optical systems.

We manufacture plano-convex, plano-concave, biconvex, biconcave, and meniscus cylindrical lenses in both positive and negative powers. We also produce custom shapes including rectangular, square, and round cylindrical lenses.

We fabricate cylindrical lenses from BK7, fused silica, CaF2, ZnSe, Si, Ge, sapphire, and other optical glasses and crystals. Material selection is based on your wavelength range, power handling, and environmental needs.

Dimension tolerances follow our common parameters: diameter +0.00/-0.10mm and center thickness ±0.15mm in Commercial grade, tightening to +0.00/-0.025mm and ±0.05mm in Precision grade, and +0.00/-0.010mm and ±0.02mm in High Precision grade. Cylinder radius is held to ±0.2% with irregularity at 1.0 wave PV in Commercial grade, reaching ±0.1% radius and λ/4 PV irregularity in Precision grade, and ±0.025% radius and λ/20 PV irregularity in High Precision grade. Axis alignment is typically within ±0.5 degrees.

Yes, we can manufacture acylindrical (aspheric cylinder) lenses for applications requiring diffraction-limited line focusing. These are produced using CNC grinding and polishing with metrology verification.
