Rapid Prototyping of Custom Optics — From Concept to Reality

Accelerating Innovation with Precision Prototyping

At Yighen Ultra Precision, we help optical engineers and product developers move from concept to reality—fast. Whether you're validating a new design, testing a novel optical system, or preparing for volume production, our prototyping services ensure precision, speed, and flexibility.

With in-house ultra-precision diamond turning, freeform machining, and optical metrology, we deliver rapid prototyping of aspheric lenses, freeform optics, plastic micro lenses, and infrared glass components, all under one roof.

Why Choose Yighen for Optical Prototyping?

• Fast Turnaround: From 3D modeling to physical components in as fast as 7 days.

• High Accuracy: Form accuracy up to P-V ≤ 0.1 µm, surface roughness down to Ra ≤ 1.0 nm.

• Versatile Materials: PMMA, PC, COP, APEL, ZEONEX, CaF₂, MgF₂, and more.

• Freeform Capabilities: Complex geometries made possible by five-axis diamond turning.

Whether for AR/VR optics, LiDAR systems, medical imaging, or custom photonics, our prototypes meet real-world performance demands with production-ready quality.

Materials We Prototype

We support a wide range of optical-grade materials used in early-stage validation:

● Optical Plastics (Block Material)

• PMMA

• PC

• COP (Zeonex®, Topas®)

• APEL™, OKP-1

• MR-8, MR-10, MR-174

• E48R, CR-39

All plastic optics are directly machined using single-point diamond turning, enabling mirror-quality surfaces for both aspheric and freeform lenses.

● Infrared & Glass Optics

• Calcium Fluoride (CaF₂)

• Magnesium Fluoride (MgF₂)
  → Machined by diamond turning

• Optical Glasses (e.g., N-BK7, SF11, fused silica)
  → Machined by ultra-precision grinding machines

❗Note: CNC is only used for pre-shaping blanks—not for optical surface generation.

Core Prototyping Equipment

Yighen operates one of the most advanced ultra-precision machining labs in Asia. Our key machines include:

• NanoTech 650 FG (5-axis)

  • Form Accuracy: P-V ≤ 0.15 μm

  • Surface Roughness: Ra ≤ 3.0 nm

  • Work Envelope: Ø650 mm (customizable)

  • Resolution: 0.01 nm linear / 0.0000001° angular

• NanoTech 250 (3-axis)

  • Form Accuracy: P-V ≤ 0.1 μm

  • Surface Roughness: Ra ≤ 2.0 nm

  • Spindle Accuracy: 12.5 nm axial/radial

• NanoForm 200 (2-axis)

  • Form Accuracy: P-V 0.15 μm (within 75 mm)

  • Ra ≤ 2 nm

• Toshiba ULC-100F(S)

  • Resolution: 0.0000001 mm

  • Pv: 0.010 μm, Ra: 0.001 μm (mold-grade quality)

These platforms allow for deterministic machining of non-rotational surfaces, micro-structured optics, and off-axis designs, ensuring optical performance from the prototype stage.

Typical Workflow

1. Design Consultation
   Feasibility evaluation, tolerance analysis, material recommendation.

2. Optical Blank Preparation
   CNC pre-machining to approximate geometry (non-optical surface only).

3. Ultra-Precision Machining
   Using diamond turning or grinding, depending on material.

4. Inspection & Metrology
   Surface roughness, form error (P-V/RMS), centration, and focal accuracy.

5. Delivery & Feedback Loop
   Short cycle for iterative refinement.

Applications

• Aspheric and freeform optical systems

• High-performance imaging lenses

• Infrared and thermal imaging optics

• Medical diagnostics and endoscopy

• Compact AR/VR optical engines

• Optical communication systems
