Custom Plano-Concave Lenses for Laser Optics

Custom Plano-Concave Lenses for Laser Optics
Product Description
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.
