| fluorescence microscope | <instrument, microscopy> A microscope illuminated by ultraviolet or blue light so that the object may re-radiate light of longer wavelengths. To protect the eyes, a W-absorbing filter should be provided if not built into the fluorescence microscope. (05 Aug 1998) |
|---|---|
| fluorescent microscope | <instrument> A microscope equipped to examine material that fluoresces under ultraviolet (UV) light. (12 Dec 1998) |
| flying spot microscope | <instrument> A microscope in which a moving spot of light is imaged in the object plane, the energy transmitted by the specimen being detected with a photoelectric cell; the light source may be a cathode ray tube, a scanning disk or drum, or an oscillating mirror. (05 Mar 2000) |
| laser microscope | <instrument> A microscope in which a laser beam is focused on a microscopic field, causing it to vaporise; the emitted radiation is analyzed by means of a microspectrophotometer; at a low intensity the laser is employed as the light source in an interference microscope. (05 Mar 2000) |
| light microscope | <instrument> The most common type of microscope (a device used to magnify small objects or substances) used in laboratories. The device works by passing visible light through a condenser and an objective lens. (09 Oct 1997) |
