🟦 Achromatic Lenses

High-Precision Achromatic Lenses for Color-Corrected Optical Systems

Achromatic lenses are specially engineered to correct chromatic aberrations by bringing two wavelengths—typically red and blue—into the same focus. This results in sharper, color-accurate imaging and improved performance across broadband light sources. At Yighen Ultra Precision, we specialize in the design, prototyping, and production of custom achromatic lenses for high-performance imaging, laser systems, life sciences, and instrumentation.

We provide both cemented achromats and air-spaced achromatic doublets, manufactured with meticulous precision to meet your exact system requirements.

🔹 Key Capabilities

• Glass types: Crown & flint glass combinations (e.g. N-BK7 + SF5, N-SF11 + F2)

• Diameter range: From Ø3 mm to Ø150 mm

• Design wavelengths: Visible, NIR, SWIR custom ranges

• Surface accuracy (P-V): ≤0.1 μm

• Centration tolerance: ≤1 arcmin

• Coating options: V-coating, broadband AR, laser line AR, custom filters

🔹 Why Use Achromatic Lenses?

🔹 Applications

Our custom achromatic lenses are widely used in:

• Microscopy and fluorescence imaging

• Laser focusing and beam shaping

• Telescopic and astronomical optics

• Machine vision and inspection systems

• Medical devices (e.g. endoscopy, ophthalmology)

• Portable optical sensors and photonics R&D

Example: Yighen supplied AR-coated achromatic doublets for a fluorescence microscopy application, enhancing light throughput by 22% while eliminating color fringing under broadband illumination.

🔹 Prototyping & Customization

From fast-turnaround prototypes to volume manufacturing, Yighen supports your entire product lifecycle:

• In-house optical design and achromat prescription matching

• Ultra-precision grinding and polishing of both lens elements

• Cemented doublet bonding under cleanroom conditions

• Air-spaced doublet assembly with aluminum or stainless spacers

• High-end centering and coating processes

Our engineers optimize each achromatic lens design for your desired working distance, wavelength range, and mechanical integration needs.

🏭 Factory Production & Optical Testing

Yighen’s production facility in Dongguan, China, includes:

• Precision grinding and polishing machines (Toshiba ULG series)

• Diamond turning for customized lens elements (NanoTech & Toshiba ULC series)

• Metrology lab with interferometry, spectrophotometers, and MTF stations

• Optical cementing and inspection under ISO cleanroom conditions

💬 Frequently Asked Questions (FAQ)

Q: What is the difference between cemented and air-spaced achromatic lenses?
A: Cemented achromats are compact and offer strong color correction. Air-spaced doublets are more flexible in design and suitable for higher power applications.

Q: Do you support multi-element assemblies?
A: Yes. We design and build full lens assemblies, including achromatic lens groups, mounts, and housing.

Q: What is the typical lead time for a custom achromat?
A: Prototypes can be delivered in as fast as 2–3 weeks. Volume production takes 4–6 weeks, depending on coatings and bonding processes.
