🔷 Light Pipe Homogenizing Rods

Uniform Light, Compact Form – Precision Light Pipe Manufacturing at Yighen

Light pipe homogenizing rods are critical components used in optical systems to transform non-uniform or patterned light sources—such as LEDs, laser arrays, or arc lamps—into a smooth, evenly distributed output beam. These solid rods use total internal reflection (TIR) to mix and homogenize light spatially and angularly, delivering consistent brightness and beam quality at the output.

At Yighen Ultra Precision, we design and manufacture custom light pipes, integrator rods, and homogenizing bars using high-purity optical materials and ultra-precision machining methods tailored to your wavelength, footprint, and system performance requirements.

🔹 What Is a Light Pipe Homogenizing Rod?

A light pipe is a solid rectangular or cylindrical rod, usually made of optical glass or polymer, designed to:

• Mix spatially inhomogeneous light via multiple internal reflections

• Even out color variations from multi-LED or multi-laser sources

• Shape beam profiles (round to square, square to rectangular, etc.)

• Maintain optical power with minimal loss

Light pipes are commonly used in projection systems, medical illumination, machine vision lighting, and sensing applications that require consistent beam output.

🔹 Shapes & Geometries We Support

We offer input/output face polishing, AR coatings, and edge blackening to improve efficiency and reduce unwanted light scatter.

🔹 Material Options

Yighen offers light pipe rods in a variety of optical materials to suit different spectral regions:

• Optical Glass (BK7, B270, fused silica) – Ideal for visible and UV

• Optical Polymers (PMMA, ZEONEX, TOPAS) – Lightweight, prototyping or low-cost builds

• IR Materials (CaF₂, ZnSe, IR-grade PMMA) – For IR and thermal imaging

• Custom Coatings – AR, HR, or diffusive depending on application

We also support diamond turning of rods for high-precision surfaces, especially in polymer-based systems.

🔹 Applications of Light Pipes

Yighen's homogenizers are especially suited for DLP, LCD, LCoS, and laser-scanning projection systems.

❓ FAQ

Q: Can you simulate beam uniformity before manufacturing?
A: Yes, we offer optical simulations using LightTools or Zemax to validate your design.

Q: Do you offer blackening for the sides of the rod?
A: Yes, sidewall blackening is available to suppress stray light and improve beam contrast.

Q: How fast can I get a prototype?
A: For standard shapes in PMMA or ZEONEX, we can produce samples within 10–15 working days.
