Features

Plano convex

1. One flat surface and one convex surface.
2. More suitable for high turnover cutting applications, and when the cost is more important than the level of accuracy.
3. When cutting thick materials, a Plano-convex lens provides a greater cut width.
4. It is more popular in American and Chinese machinery.

Meniscus

1. One concave surface and one convex surface.
2. Creates a smaller beam diameter, reducing the spherical aberration and beam waste when precision cutting or marking.
3. Provides a smaller spot size with increased power density at the work piece.
4. It usually used by European customers and machine manufacturers (OEM's).
5. Meniscus lenses are more expensive than Plano-Convex lenses.
