🟦 Optical Prisms

Precision Optical Prisms for Beam Steering, Splitting, and Imaging Systems

Optical prisms are essential in redirecting, reflecting, dispersing, and manipulating light in a wide range of photonic systems. At Yighen Ultra Precision, we specialize in the manufacturing of custom optical prisms with exceptional surface flatness, tight angular tolerances, and precision alignment for high-performance optical assemblies.

Whether you need right-angle prisms for beam reflection, dispersive prisms for spectral separation, or custom-shaped glass prisms for imaging systems, our team can deliver both prototypes and high-volume orders—crafted to the most demanding specifications.

🧠 Frequently Asked Questions

Q: Do you offer beam-splitting cube prisms with specific T/R ratios?
A: Yes, we can provide cube prisms with custom transmission/reflection ratios (e.g., 50/50, 70/30), dielectric or metallic coatings.

Q: Can prisms be bonded without glue?
A: Absolutely. We offer optical contact bonding, ideal for high-purity systems with no outgassing or UV interference.

Q: Do you support prisms for high-laser damage threshold applications?
A: Yes. We offer LDT coatings and process prism surfaces to meet the needs of high-power laser systems.
