An axicon lens is a specialized type of lens which has a conical surface. An axicon images a point source into a line along the optic axis, or transforms a laser beam into a ring. It can be used to turn a Gaussian beam into an approximation to a Bessel beam, with greatly reduced diffraction. Axicons lenses are used in atomic traps and for generating plasma in linear accelerators. They are used in eye surgery in cases where a ring-shaped spot is useful. Axicon lens is usually characterized by the ratio of the diameter of the ring to the distance from the lens tip to image plane.

Applications:
• Laser Drilling/Optical Trepanning
• Optical Trapping
• Optical Coherence Tomography (OCT)
• Corneal Surgery
• Telescopes
• Solar Concentrators

Achromatic lenses are doublet systems consisting of one crown and one flint element, cemented together along a matching curvature, so that white light coming into the lens is all focused (imaged) at the same point on the other side of the lens.They are designed to minimize spherical and chromatic aberrations for infinite conjugate, visible spectrum imaging applications. When used on-axis, an achromatic lens focuses an parallel input beam to a perfect “point”, limited only by the effects of diffraction. This performance can be achieved over a broadband of wavelength. Achromatic lenses can be used to collimate and focus laser beams. They can also be used for high-quality imaging on-axis. However, the off-axis performance is significantly worse than the on-axis performance. If your application requires good optical performance off-axis as well as on-axis, multi-element lenses.

CRYLIGHT is dedicated to manufacturing high precision spherical lens from rapid prototyping to volume production.  We have years of experience in lens manufacturing, design and optical presision assembly.

The Plano Convex Lenses are made from BK7 material. It presents a curved interface and a planar interface. They are for instance the microlenses situated on top of a wafer, but can also encountered in macroscopic optical systems. Their asymmetrical nature influences their properties of bending the light. Depending on their role in an optical system, their orientation has to be taken into account.
