Optical coherence tomography (OCT), a noninvasive imaging technology, is a standard diagnostic tool used in the field of ophthalmology. With the advent of new compact form factors for the modality,...

Researchers from the University of Twente have developed a multifunctional photonic integrated circuit (PIC) that enables programmable filtering functions with a reported record-high dynamic range....

The benefits of aspheric lenses are numerous: They allow for a reduction in spherical aberrations and are ideal for focusing or collimating light, as they can achieve a low ƒ-number. Aspheres...

With the understanding of aspheric lens manufacturing provided in part one of this article, designers have the tools to optimize their aspheres; the next step is to understand how to specify and...

An interferometer is an instrument that compares the position or surface structure of two objects. The basic two-beam division of amplitude interferometer components consists of a light source, a...

In their earliest forms, UV bandpass filters that were optimized for wavelengths less than 400 nm, such as the Schott UG or the Hoya U-series, were constructed of absorbing compounds in glass. Such...

Optical manufacturing has become increasingly challenging as specifications tighten for wavefronts, form, slopes, and mid-spatial frequency features. Interferometers are essential tools to control...

Modern computer numerical control (CNC) polishing has revolutionized optical component manufacturing by enabling both more precise and wilder surface shapes to be deterministically manufactured....

The practical application of interferometers to optical component and system testing was enabled by the invention of the laser. White light interferometers were nearly impossible to use with...

Optical measurements are ideally suited to study the smallest changes in a parameter or a signal of importance to a physical system. This is the case for the minuscule length changes tracked by...

A Mach-Zehnder interferometer is an optical device used to measure the phase difference between two collimated beams of light. It is named after the physicists Ludwig Mach and Ludwig Zehnder, who...

A mirror mount is a mechanical device used to secure and precisely position mirrors in optical systems. Mirrors are essential components in optical setups for reflecting light or redirecting laser...

A lateral shearing interferometer is an optical device used in interferometry to measure phase differences between two beams of light. Interferometry is a technique that combines and analyzes...

Laser optics refers to a broad category of optical components and systems designed for manipulating and controlling laser light. Laser optics play a crucial role in shaping the characteristics of...

A Twyman-Green interferometer is a testing device that provides a contour map of the emergent wavefront for the observer in terms of the given wavelength of the light.
