This review focuses on recent developments in additive manufacturing (AM) of precision
optical devices, particularly devices consisting of components with critical features at the …

Freeform optics has become the most prominent element of the optics industry. Advanced
freeform optical designs supplementary to ultra-precision manufacturing and metrology …

Freeform optics aims to expand the toolkit of optical elements by allowing for more complex
phase geometries beyond rotational symmetry. Complex, asymmetric curvatures are …

Metamaterials are engineered materials conceived and designed to achieve very special or
even unique physical properties, which depend on the designed micro or nanostructures …

3D-inkjet-printing is just beginning to take off in the optical field. Advantages of this
technique include its fast and cost-efficient fabrication without tooling costs. However, there …

A method based on subaperture stitching for measurement of a freeform wavefront is
proposed and applied to wavefronts calculated from the slope data acquired using a …

In this study, a focus-tunable liquid cylindrical lens based on electrowetting was designed
and fabricated. The cylindrical cavity usually used in common electrowetting zoom spherical …

A Cassegrain antenna system and an optical fiber coupling system which consists of a plano-
concave lens and a plano-convex lens are designed based on the vector theory of reflection …

We present design and manufacture of a 3D printed varifocal freeform optics. The optical
refraction power can be tuned continuously by mutual rotation of two helically shaped lens …

A compact optical zoom camera module with Alvarez freeform elements is reported. A 3×
magnification in the optical zoom system was achieved by means of lateral shifting two pairs …
