🟦 Aspheric Lenses

Precision Aspheric Lenses for Advanced Optical Systems

 

 

 

Aspheric lenses are engineered to correct spherical aberration and minimize optical distortion, offering superior image quality and performance compared to traditional spherical optics. At Yighen Ultra Precision, we specialize in the design, prototyping, and manufacturing of high-precision aspheric lenses—crafted from both glass and plastic substrates—for industries ranging from imaging and lighting to medical diagnostics and laser systems.

Whether you're developing a high-resolution camera, a laser collimation module, or an optical measurement system, custom aspheric lenses can significantly enhance system efficiency, reduce weight, and lower your total component count.

 

 

🔹 Key Capabilities

• Materials: Optical glass (e.g. N-BK7, CaF₂, MgF₂), optical plastics (PMMA, COP, ZEONEX®, APEL™, etc.)

• Forming methods: Diamond turning, ultra-precision grinding & polishing

• Surface roughness (Ra): Down to 1.0–2.0 nm

• Form accuracy (P-V): ≤0.1 μm

• Coatings: AR, HR, filter coatings, IR coatings available

• Max diameter: Up to Ø200 mm for custom aspheric optics

 

 

🔹 Why Use Aspheric Lenses?

Feature	Advantage
Eliminates spherical aberration	Sharper focus, improved resolution
Reduces number of elements	Smaller, lighter assemblies
Enhances optical efficiency	Higher transmission, better SNR
Customizable shapes	Fit to your specific optical path
Precision molding & machining	Scalable for prototype or volume

 

 

🔹 Applications

Our custom and molded aspheric lenses are used in:

• Laser beam collimation and focusing

• Smartphone and mobile camera modules

• Medical imaging (OCT, endoscopy)

• Automotive LiDAR and HUD systems

• Fiber-optic communication and sensors

• AR/VR optical modules and waveguides

Case Example: We recently delivered molded aspheric optics for a VR headset supplier, reducing optical distortion by 35% while keeping the module below 5g in weight.

 

 

🔹 Prototyping & Mass Production

Whether you're in early-stage prototyping or preparing for high-volume production, we support both:

• Fast turnaround aspheric prototyping from bulk materials (plastic/glass)

• Diamond turning for ultra-precise low-volume needs

• Precision injection molding with custom-designed mold inserts

• In-house tooling & ultra-precision metrology (e.g., interferometry, profilometry)

 

 

🔹 Optical Coatings & Assembly Support

We offer in-house optical coating services for all aspheric lenses, including:

• Broadband AR coatings (visible, NIR, SWIR)

• Dielectric mirrors

• High-durability IR coatings

• Hydrophobic/oleophobic layers

Integrated opto-mechanical assembly services are available for projects requiring full module delivery.

 

 

🟨 Our Factory Advantage

All aspheric lenses are produced at Yighen's  precision optics factory, equipped with:

• 5-axis ultra-precision freeform diamond turning (NanoTech 650 FG)

• High-speed ultra-precision grinders (Toshiba ULG-100D)

• In-house tooling workshop for optical mold inserts

• Class 1000 cleanroom assembly for sensitive optics

 We own and operate our manufacturing site, ensuring quality, cost, and delivery you can rely on.

 

 

💬 Frequently Asked Questions (FAQ)

Q: What materials are available for aspheric lens production?
A: We offer a wide range of optical glasses (e.g. N-BK7, CaF₂, SF11) and plastics (PMMA, PC, ZEONEX®, COP, etc.), selected based on application requirements.

Q: What's the typical lead time for custom aspheric optics?
A: Prototype turnaround can be as fast as 2–3 weeks, while volume molding programs typically require 4–6 weeks after mold completion.

Q: Do you support lens + housing integration?
A: Yes. We provide full optomechanical design, lens mounting, adhesive bonding, and alignment solutions.
