Supplier's note

1. Key Breakthroughs:

   • The green film coating reduces surface reflection by 98%, outperforming traditional AR coatings (75% reduction).
   • The beveled edges minimize light scatter by 40%, enhancing image sharpness.
   • ISO 1413:2019 compliance ensures compatibility with global optical systems.

2. Version Selection Guide:

   • Base Model: Ideal for casual astronomers or educators needing cost-effective performance.
   • Advanced Model: Best for serious hobbyists requiring higher clarity and precision in astrophotography.
   • Pro Model: Tailored for professional observatories or R&D labs demanding extreme durability and thermal stability. For instance, the Pro’s nanotech coating allows stable operation in extreme temperatures (-40°C to 80°C), critical for field research. Pair its low edge tolerance with high-end mounts for unmatched alignment accuracy.

With the Pro Model’s nanotech coating, you can capture celestial details in harsh environments. With the Advanced Model’s multi-layer coating, you achieve 20% sharper images than standard lenses. Choose wisely based on your application’s precision and environmental demands.
