Alicona's EdgeMaster optical 3D measuring system being used by Matt Bollman at IMCO Carbide Tool. (sme.org)
IMCO was so impressed by the easy operation and robustness of the optical measuring system in its R&D center that a second EdgeMaster was purchased and is now being used in production operations. (sme.org)
Older Apple iOS products sold at a discounted price, like the iPhone 3GS and first-generation iPad, are often more popular than newer devices running the Google Android operating system, a new report claims. (appleinsider.com)
For the produced device to function properly, the laser, the resonator, and the optical phase between them must be controlled to create a coupled system based on the "self-injection locking" phenomenon. (photonics.com)
Because of an increase in the complexity of medical devices and patient interventions, it has become more difficult for perioperative staff members to ensure that equipment is properly used and disinfected according to the manufacturer's instructions for use and the Spaulding classification system.

These measurements can be used to describe the optical properties of the eye and to detect optical irregularities of the visual system that contribute to visual quality. (medscape.com)
In ophthalmology, the eye is viewed as an optical system. (medscape.com)
The local slope of the wavefront curve at the particular spot within the pupil is derived from the actual image displacement of the point source from foveola as it passes through the optical system of the eye as compared to the ideal/predicted image of the ideal optical system. (medscape.com)
All the rays from an object that are entering the eye with an ideal optical system should focus in the foveola. (medscape.com)
Ideal wavefront of an optical system with no aberrations in place. (medscape.com)

Though several other teams have recently demonstrated very compact combs by placing a semiconductor laser chip and a separate silicon nitride ring-resonator chip very close together, the laser and the resonator in those works were still separate devices, made independently and then placed in close proximity to each other perfectly aligned. (photonics.com)
The final device consists of eight platinum wire electrodes, a glass tube, and a helium neon laser. (cdc.gov)
