Product Advantages & Applications

Lightweight Durability: Approximately 50% lighter than glass rods of the same dimensions, reducing overall weight of portable optical instruments.
High Impact & Scratch Resistance: Superior surface hardness compared to PMMA, offering excellent resistance to abrasion and impact.
Superior UV Stability: Natural resistance to yellowing under UV exposure, preserving spectral purity.
Diverse Application Fields:
- Medical Diagnostics: Non-fragile light guide in portable diagnostic sensors and lab-on-a-chip devices.
- Industrial Sensing: Integration in chemical processing plants with resistance to corrosive vapors.
- Optoelectronics: Precision-ground coupling between LEDs and fiber optic arrays.
- Automotive Lighting: Ambient interior lighting components requiring heat resistance and clarity.

Frequently Asked Questions

Why is CR39 preferred over Polycarbonate for an Optical Rod?

While Polycarbonate is tough, it has a high level of "birefringence" (internal stress) and a lower Abbe value. CR39 Optical Rod provides a much cleaner optical path with significantly less color fringing, making it the superior choice for imaging and precise light guidance.

How do you achieve a ±0.005mm diameter tolerance on a polymer CR39 Optical Rod?

We utilize specialized centerless grinding techniques specifically calibrated for thermoset polymers, achieving ±0.005mm precision typically seen only in glass components.

Can the CR39 Optical Rod be AR coated?

Yes. We have developed a proprietary low-temperature vacuum deposition process that allows us to apply Anti-Reflection (AR) coatings without compromising the substrate's structural integrity.

Is the CR39 Optical Rod resistant to sterilization chemicals?

Absolutely. CR39 Optical Rod is highly resistant to most common sterilizing agents and alcohols used in medical environments, providing significant advantage over acrylic rods that may craze or crack.

What is the maximum length available for a custom CR39 Optical Rod?

We can manufacture CR39 Optical Rod in lengths up to 300mm, maintaining strict straightness and diameter consistency throughout the entire span.
