Product Description

Fused Quartz Positive and Negative Meniscus Lenses

Meniscus Lens

Meniscus lenses have one concave surface and one convex surface.
Creates a smaller beam diameter, reducing the spherical aberration and beam waste when precision cutting or marking.
Provides a smaller spot size with increased power density at the work piece.

Positive lenses are lenses which are thicker at the center than at the edge.The combined effect of refraction at the front and back surface of the lens will bend light to a point or focus-the light from this type of lens is focused to a point in front of the lens.

Concave-convex lenses are also called meniscus lenses. The lens has an external convex surface and an internal concave surface. If the radians outward are greater than the radians inward, the lens has a regular focal length and is used as a magnifying glass
