Optical manufacturing and testing is the process of manufacturing and testing optical components. It spans a wide range of manufacturing procedures and optical test configurations. The manufacture of a conventional spherical lens typically begins with the generation of the optic's rough shape by grinding a glass blank. [1]
Optical lens design is the process of designing a lens to meet a set of performance requirements and constraints, including cost and manufacturing limitations. Parameters include surface profile types (spherical, aspheric, holographic, diffractive, etc.), as well as radius of curvature, distance to the next surface, material type and optionally tilt and decenter.

In November 2017, Hakim Optical partnered with virtual reality and augmented reality agency VusionVR Inc. to expand the in-store service by offering an app that would take a customer's selfie and apply a Snapchat-like filter of the ...
On the tool surface, highly adherent thin coatings are synthesized. Materials for coatings on optical inserts are Platinum-based PVD (mostly iridium-alloyed, standard), diamond-like carbon (not yet commercially available), SiC (CVD) on SiC-ceramics (not yet commercially available, have to be post-machined) or TiAlN (not yet commercially available).
An optical instrument is a device that processes light waves (or photons), either to enhance an image for viewing or to analyze and determine their characteristic properties. Common examples include periscopes , microscopes , telescopes , and cameras .
