Custom Plano Concave Lenses For Laser Optics

Products Photos Catalog Plano Concave Lenses Photos Catalog

Plano-concave lenses convert incoming parallel light rays into diverging beams that appear to come from a point in object space, the so-called imaginary focal point.

Like plano-convex lenses, these lenses have the least image aberration at absolute conjugate ratios greater than 5 or less than 1/5 - For this reason, plano-convex lenses should be placed so that the parallel beam enters the curved surface of the Optical lens.

However, when a plano-convex lens is used to disperse a high-power pulsed laser beam, this orientation of the lens can be detrimental, with stationary reflections from the curved surface creating secondary focusing that can damage the optics in front of the concave lens and even cause the laser to collapse at that point.

Therefore, in high power applications, the concave surface should be oriented in such a way as to avoid secondary focusing.
