🔷 High-Performance Optical Mirrors – Designed & Manufactured by Yighen

At Yighen Ultra Precision, we specialize in the design and manufacturing of high-performance optical mirrors for demanding applications in laser systems, imaging devices, biomedical instruments, and optical measurement setups. Whether you need a standard flat mirror or a custom curved, off-axis, or coated mirror, we offer tight-tolerance fabrication and coatings tailored to your needs.

With in-house ultra-precision machining and coating capabilities at our Dongguan facility, we deliver mirrors with exceptional flatness, reflectivity, and surface quality—ready for integration into your optical assemblies.

 

 

🔶 Types of Optical Mirrors We Offer

We manufacture and customize the following mirror types:

• Flat Mirrors
  Ideal for beam folding, reflection, and optical paths.

• Concave & Convex Mirrors
  Used for focusing or expanding light in imaging or laser systems.

• Off-Axis Parabolic Mirrors (OAP)
  Ideal for collimation and focusing without introducing spherical aberration.

• Metallic & Dielectric Mirrors
  Coated to optimize reflectivity across UV, visible, NIR, or IR spectra.

• Custom Mirror Shapes
  Elliptical, rectangular, slotted, or with mounting holes for optomechanical integration.

❓ Frequently Asked Questions

Q: What’s the difference between dielectric and metallic mirrors?
A: Metallic mirrors offer broad reflectance across the spectrum, while dielectric mirrors provide higher reflectivity but are wavelength-specific and angle-sensitive.

Q: Can you make elliptical mirrors for laser scan systems?
A: Yes, we routinely manufacture elliptical mirrors with custom bevels and chamfers for scanning assemblies.

Q: Do you support laser-grade flat mirrors?
A: Absolutely. Our laser mirrors are LDT-optimized and available with 10-5 surface quality and λ/20 flatness.
