Cylindrical Lenses – Precision Manufacturing at Yighen

Cylindrical lenses are essential components in many advanced optical systems, enabling beam shaping, line focusing, and astigmatic correction. At Yighen Ultra Precision, we specialize in the custom design and manufacturing of cylindrical lenses, offering high-precision prototypes and scalable mass production to meet demanding application needs.

✅ What Are Cylindrical Lenses?

Unlike spherical lenses that focus light in two dimensions, cylindrical lenses focus or expand light in just one axis. This makes them ideal for:

• Laser line generation

• Optical scanning systems

• Bar code readers

• Medical laser systems

• Cylindrical anamorphic optics

• Spectroscopy and interferometry

•  

Q: What are optical cylindrical components used for?

A: Optical cylindrical components are commonly used in laser line generation, beam shaping, and scanning applications. Yighen offers custom cylindrical optics with high precision surface quality and fast turnaround times.

🛠 Our Manufacturing Capabilities

Yighen combines world-class equipment with optical manufacturing expertise to deliver high-accuracy cylindrical lenses from both glass and optical plastics. Our capabilities include:

• Ultra-Precision Grinding for Glass Lenses

For materials like BK7, fused silica, quartz, and optical crown glass, we employ high-end Toshiba ULG-100D and ULG-100D(H3) ultra-precision grinding machines. These achieve:

• Form accuracy (P-V): ≤0.030μm

• Surface roughness (Ra): ≤0.01μm

• Diamond Turning for Plastic and IR Materials

We use NanoTech 250, NanoForm 200, and Toshiba ULC-100F(S) for single-point diamond turning (SPDT), ensuring:

• Surface roughness as low as Ra 0.001μm

• Form error under 0.1μm

• Ideal for PMMA, COP, ZEONEX, and CaF₂, MgF₂, Ge, ZnSe

🧩 Customization & Tolerances

Yighen supports fully customized cylindrical lenses based on your optical layout. Our typical specification ranges:

• Focal Length: from 1 mm to 500 mm

• Diameter / Width: 1 mm to 150 mm

• Thickness Tolerance: ±0.02 mm

• Centering Accuracy: <3 arcmin

• Surface Quality: 20-10 to 60-40 (MIL-PRF-13830B)

Optional coatings include AR, BBAR, UV-VIS, and NIR for enhanced performance.

📦 Materials We Support

We work with a wide range of materials to fit your budget and optical requirements:

Glass Materials:

• BK7, Fused Silica, Quartz

• CaF₂, MgF₂, SF11, LaK types

Optical Plastics:
