Exempel på hur man kan använda DIOPTRIC i en mening

• The simpler dioptric (purely refractive) form of the lens was first proposed by Georges-Louis Leclerc, Comte de Buffon, and independently reinvented by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses.
• A refracting telescope (also called a refractor) is a type of optical telescope that uses a lens as its objective to form an image (also referred to a dioptric telescope).
• Later, the single light was replaced by a pair of small (fifth-order) revolving dioptric optics, each of which produced a single flash every 10 seconds; they were mounted in small turrets on opposite sides of the tower: one shone red towards the north-west, the other shone white towards the south-east (their arcs overlapped, so that vessels approaching from seaward would see the red light as well as the white if their course took them too close to St Catherine's Point, approaching from the west, or Selsey Bill, approaching from the east).
• The fixed eye-level pentaprism viewfinder has 100-percent vertical and horizontal coverage, has dioptric viewfinder adjustment from –3 to +1 diopter and has as a viewfinder eyepiece blind to block stray light when on a tripod.
• The topographical map can be represented in a number of graphical formats, such as a sagittal map, which color-codes the steepness of curvature according to its dioptric value.
• The light was created by a burner fuelled by kerosene, which generated 20,000 candlepower and itself was dioptric occulting type.
• Uses dioptric / parallax focusing, for astrophotography, photomicrography, or other high-magnification uses.
• The station was automated on 7 January 1959 and the dioptric lens with its revolving machine and vaporised paraffin incandescent burner were replaced by a new fourth order cylindric refractor lens.
