Optical System Alignment, Tolerancing, and Verification XIII.
Optical systems are often athermalized over large temperature ranges through the proper choice of glasses and mounting materials. However, variations in the coefficients of thermal expansion (CTE) and thermo-optical coefficients that govern thermal b

In the design of optical assemblies, emphasis is placed on tolerancing the surface irregularity, which is a driving factor in price and manufacturing prices and time during polishing. Quite often, the default irregularity tolerance in modeling softwa

Optical Manufacturing and Testing XII.
As aircraft design advances, the requirements on the aerodynamics of such aircraft become much more stringent. The use of conformal windows on such aircraft enables better aerodynamics by eliminating the need for protruding sensor packages, thereby r

Systems like TESS require specialized components that challenge all involved. These systems consist of many sub-components, but we are focused on the refractive and reflective optical components. One purpose of this talk is to introduce optical syste

Additive manufacturing, or 3D printing, has become widely used in recent years for the creation of both prototype and end-use parts. Because the parts are created in a layer-by-layer manner, the flexibility of additive manufacturing is unparalleled a

Freeform and conformal optics have the potential to dramatically improve optical systems by enabling systems with fewer optical components, reduced aberrations, and improved aerodynamic performance. These optical components differ from standard compo

Typically, a monolithic telescope describes a single mirror substrate fabricated from one initial blank which would serve as one reflective surface in an off-axis telescope design. This presentation describes a telescope design in which all optical s

Sapphire presents many challenges to optical manufacturers due to its high hardness and anisotropic properties. Long lead times and high prices are the typical result of such challenges. The cost of even a simple 'grind and shine' process can be proh

Freeform optical surfaces, which have little to no symmetry, are gaining popularity with lens designers and optical system integrators. These freeform optics can enhance optical performance by reducing the number of elements, enabling lighter and mor
