Supplier's note

  1. Technical Breakthroughs:

    • EPR Certification: Ensures compliance with stringent German environmental regulations, reducing deployment barriers in EU markets.
    • PMMA Material: Offers superior UV resistance compared to glass, extending lifespan in outdoor applications.
    • Precision EFL: ±0.02mm accuracy in the Pro Model enables sub-millimeter beam alignment in high-precision robotics.

  2. Version Selection Guidance:

    • Base Model: Suitable for basic laser modules (e.g., consumer electronics) where cost-efficiency is prioritized.
    • Advanced Model: Ideal for industrial sensors or medical devices requiring UV stability and tighter EFL tolerances.
    • Pro Model: Best for harsh environments (e.g., automotive manufacturing) needing IP67 sealing and thermal resistance up to 85°C.

With the Pro Model’s IP67 rating, you can deploy the lens in wet or dusty factories while maintaining optical performance. Pair its high-temperature PMMA with the ±0.02mm EFL for unmatched reliability in robotic assembly lines.
