Custom Optical Rod
Custom Optical Rods are precision components designed to guide, transmit, homogenize or deliver light in compact optical systems. Controlled material, cross-section, length, end-face geometry and surface quality enable efficient and stable beam propagation.
Custom Optical Rod Overview
Custom Optical Rods are precision components designed for light transmission, beam guidance, illumination and sensing. Optical glass, fused silica, sapphire and BK7 options support different optical, mechanical and environmental requirements.
Chenyu Optics provides controlled diameter, length, cross-section, end-face geometry, surface quality and optical coatings for stable performance in laser, imaging, sensing and illumination systems.
Each optical rod can be customized according to customer drawings, including material, diameter, length, round or polygonal cross-section, end-face angle, surface accuracy, surface quality and optical coating.
Key Advantages of Custom Optical Rods
Light Guiding, Homogenization & Beam Delivery
Custom optical rods guide and homogenize light through controlled internal reflection, delivering uniform illumination or stable beam transfer in laser, sensing and optical instrument systems.
