摘要： A level comprises a sealed casing which holds a liquid and has a flat bottom end. It also includes a light admissive top section, bearing a periodic grating of alternating transparent and opaque stripes. A float is in the liquid inside a compartment of the casing underneath the light admissive top section. The float is capable of changing its position inside the chamber so as to retain its position relative to the horizon when the chamber is filled, and a mirror on the top face of said float.

摘要： A system for determining the index of refraction of a sample fluid in which light from a collimated light source is directed through a light pervious cell in which sample and reference fluids are held. The light from the collimated light source which is transmitted through the cell is deflected and is then directed through a pair of gratings to establish patterns. When the cell contains a reference fluid therein, first patterns are established, and second patterns are then established by replacing the reference fluid with the sample fluid. A measurement of the change between the first patterns and the second patterns is used for determining the index of refraction of the sample fluid.

摘要： A method and apparatus for measuring an optical property of an optical device, such as a convex or concave reflector surface, by locating a main converging lens having a focal length f.sub.1 in front of an optical measuring system capable of measuring collimation, and providing a carrier including an auxiliary converging lens for receiving a beam from the optical measuring system, and the optical device to be tested for reflecting back, via the auxiliary converging lens to the optical measuring system, the beam passed through the auxiliary converging lens from the optical measuring system. The carrier is located at a first position wherein the back focal plane of the auxiliary converging lens coincides with the front focal plane of the main converging lens, and the optical device to be tested is located on the carrier in the front focal plane of the auxiliary converging lens. The carrier is moved to a second position wherein the beam reflected back to the optical measuring system via the auxiliary converging lens and main converging lens is found by the optical measuring system to be collimated.

摘要： A multifocal lens having far and near vision zones is presented. The lens comprises a substrate in the form of a progressive addition lens and a modulation formed on a surface of the substrate. The substrate lens has far and near vision zones, selected in accordance with respective prescribed values of optical power required for the patient's eye at his distance and reading vision, and an intermediate transition region between the far and near vision zones. The modulation is of kind producing locally variable power addition such that the far and near vision zones of the multifocal lens are wider than the far and near vision zones of the substrate.
