Two axes of motion are used by a conventional single point diamond turning (SPDT) lathe to describe a curve in space. The curve is formed between the centerline of the work piece to be machined and ...

Retinoscopy is an important part of objective refractive measurement. Traditional teaching is that on the visual axis retinoscopy should be performed to obtain accurate measurements. 1 The object of ...

We present a new interferometric and holographic approach, named interferometry with doubled imaging area (IDIA), with which it is possible to double the camera field of view while performing off-axis ...

Off-axis paraboloid reflector is a special optical element, its main function is to focus the incident light to a certain distance from the optical axis. The working principle is based on the ...

One way that Audioholics have presented on-axis and off-axis frequency responses in our loudspeaker reviews are through waterfall plots. Wikipedia defines a waterfall plot as: “a three-dimensional ...

Celestron’s Off-Axis Guider uses an adjustable, multicoated 12.5-millimeter prism that allows you to locate a guide star. It has a fixed-orientation helical focuser and includes all needed spacers and ...

Optical Surfaces Ltd is supplying high precision off-axis parabolic mirrors (120 – 350mm diameter) to OPTIKOS Corporation (Wakefield, USA) for their customer specified OpTest® optical testing systems.

This video reviews the types of target magnetic systems and applications that are supported by circular vertical hall technology-based angle sensor ICs. Circular Vertical Hall or CVH technology ...

Earth's axis — the invisible line around which it spins — is bookended by the north and south poles. The axis tilts, and thus the pole shift, depending on how weight is distributed across Earth's ...

The advent of four axis SPDT enables the generation of non-axisymmetric surfaces. This tool has two extra motions in addition to the orthogonal two axes of motion (x and z axes) featured in a SPDT ...
