For actuators, micropositioning systems and microscope stages, PI (Physik Instrumente) LP has introduced the C-867, a two-axis digital controller for ultrasonic high-stability piezo motor stages such as those used on the latest-generation microscopes. Optimized for piezo linear motors, it features dynamic servo parameter switching for faster settling; integrated drive electronics for ultrasonic motors; USB, RS-232 and joystick interfaces; 4 + 4 programmable transistor-transistor logic inputs/outputs for flexible automation; a data recorder and macro programming language; daisy-chain networking for up to 16 axes; and extensive software support, including LabView and dynamic link library. Applications include biotechnology, microscopy, fiber positioning, automation, photonics/integrated optics, quality assurance testing and testing equipment.

integrated optics
A thin-film device containing miniature optical components connected via optical waveguides on a transparent dielectric substrate, whose lenses, detectors, filters, couplers and so forth perform operations analogous to those of integrated electronic circuits for switching, communications and logic.
An instrument consisting essentially of a tube 160 mm long, with an objective lens at the distant end and an eyepiece at the near end. The objective forms a real aerial image of the object in the focal plane of the eyepiece where it is observed by the eye. The overall magnifying power is equal to the linear magnification of the objective multiplied by the magnifying power of the eyepiece. The eyepiece can be replaced by a film to photograph the primary image, or a positive or negative relay...
microscope stage
The component of a microscope on which the sample or slide to be examined is placed. Depending on the design of the microscope, the stage may play a passive role of just supporting the sample or slide being viewed, or it may be moved as part of the focusing process.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
