Biconvex lens with BK7 glass or Corning UVFS glass based. Double surfaces with specific AR coated to work as focusing or special imaging systems.

The key difference lies in the anti-reflection (AR) coating. Standard lenses have a broadband AR coating that works over a wide range of wavelengths, like the entire visible spectrum. A laser line lens, however, features a laser line V-coating that is meticulously engineered to achieve near-perfect transmission (less than 0.25% reflection) at one or two specific wavelengths. This creates a “V” shaped dip in the reflection curve at the design wavelength. This coating dramatically increases the amount of light that passes through the lens and minimizes reflections that could damage the lens or create unwanted stray light in the system.
