Optical Fused Silica and Sapphire Cylinder Rod Lens: Precision in Light Manipulation

In the realm of optical engineering, the Rod Lens stands out as a specialized variant of the cylinder lens. Crafted with meticulous attention to detail, these lenses are distinguished by their highly polished circumference and precision-ground ends. The result is a component that not only mirrors the functionality of a standard cylinder lens but also excels in beam shaping and focusing collimated light into a precise line.


Manufacturing Excellence

The journey of creating a Rod Lens begins with the selection of premium materials. Optical Fused Silica and Sapphire are chosen for their exceptional properties, including high thermal stability, low coefficient of thermal expansion, and remarkable optical clarity.


1. Material Preparation: The raw materials are carefully prepared, ensuring purity and homogeneity to provide a flawless optical medium.

2. Shaping and Polishing: The cylindrical shape is achieved through a controlled grinding process. The circumference of the lens is then polished to optical-grade smoothness, allowing for optimal light transmission.

3. End Grinding: Both ends of the Rod Lens are ground with precision. This step is crucial as it determines the lens’s ability to focus light accurately.

4. Coating: To enhance performance, the lenses may receive specialized coatings. Anti-reflective coatings are applied to minimize light loss and ensure maximum efficiency in light transmission.


Applications and Performance

Rod Lenses are pivotal in numerous applications where precise light manipulation is required. They are commonly utilized in:

•  Laser Collimation: To transform divergent beams of light into parallel rays.

•  Beam Shaping: To convert point light sources into line illuminations, aiding in various scanning and measurement systems.

•  Optical Data Transmission: Serving as a medium in fiber optics, facilitating high-speed data transfer.


Quality Assurance

Each Rod Lens undergoes rigorous testing to ensure compliance with stringent quality standards. Parameters such as surface quality, dimensional accuracy, and optical performance are meticulously evaluated to guarantee that each lens performs at its peak.
