High-transmittance plano-convex lens, K9 quartz material, specialized for laser focusing/medical equipment.

A plano-convex lens is an optical element with one flat surface and the other a convex spherical surface, featuring core functions such as focusing light and collimating beams. Its design principle is based on the law of refraction of light, utilizing the curvature of the convex surface to converge or diverge incident light, while the flat surface simplifies the assembly and positioning of optical systems.

Key Technical Parameters and Material Characteristics

1. Material Selection

   • K9 Optical Glass: High transmittance in the visible light range (350-700nm), suitable for precision instruments and scientific experiments.
   • Anti-Reflection Coating Technology: Surface coated with visible light anti-reflection A-film to reduce reflection loss and improve transmission efficiency, typically used in laser equipment and imaging systems.
   • Other Materials: Such as calcium fluoride, fused quartz, etc., applicable for special wavelength scenarios in ultraviolet or infrared.
