Spheres of various curvatures and diameters can be adjusted to   customer requirements.

Aspheres are elements of rotational symmetry with a profile that deviates from that of a circle. Using aspheres in an optical system provides the optical designer with additional degrees of freedom to create a system with lower optical aberrations.

Cylindrical optics is used to focus a beam of light into a line.  The manufacturing of the resultant surfaces is attained by applying the appropriate kinematics.

Acylinders are the asperic extension to cylinderical optics, allowing for removal of higher aberrations by  producing a cross section that deviates from a circle. CNC technology  is required to manufacture the acylindrical surfaces.

Ring or barrel, we have them all. Toric surfaces are generated when an arc of a certain radius is rotated around a point using a different radius.  The second radius can be larger than the first, creating a ring-shaped surface  that is  smaller than the first, which will result in a barrel-shaped surface. Using advanced CNC technology  enables SPO to manufacture precise toric surfaces according to customer needs. Toric surfaces  can offer a variety of solutions in optical systems, particularly when there are differences between between x and y optical paths.

Similar to the relationship between  aspheric and  spheric surfaces, with  atoric  and toric surfaces the  arc that is rotated in creation of the torus can deviate from a circle with the introduction of a conic constant or aspheric coefficients, allowing the designer greater freedom in creating optical surfaces.

Freeform optics represents a group of surfaces that are limited by neither symmetry nor equation. Surfaces can be represented in different ways from polynomial equations to zernike coefficients or a points cloud. The optics of freeforms allows the optical designer the highest flexibility and can  enable the design of a system with better optical performance while saving on size and weight.

The manufacture of freeform elements is challenging in both surfacing and measurements and requires extensive knowledge and the application of compatible tools in hardware and software. SPO has enjoyed more than 20 years of development and experience in the production of freeforms.
