Optical glass concave-convex lens with Anti-reflective coating

Optical glass concave-convex lens with Anti-reflective coating

Meniscus Lenses

• 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.

Positive lenses produce a real image,the image produced by this types of lens can be projected onto a screen
