Definitions

  • the diameter of constriction 52 is smaller than that of neck 55 and the neck diameter is smaller than the internal lens diameter.
  • the lead-in wires 56 and 57 are kept in spaced relationship to each other by bead 59 and carry the filament 60.
  • the distance of filament 60 from the lens plane measured in millimetres can be in the range of between 80% and 150% of the magnitude of the ratio lens diameter to lens thickness and, in the present case, amounts to 2.08 mm.
  • the end portions 62, 63 of lead-in wires 56 and 57 are bent outwardly and bear against annular shoulder 53.
  • the prefocus base 58 is provided with an adjustment ring 61. Locating bosses 64 are mounted in customary manner on the adjustment ring 61 and corresponding stop means are provided on the Searchlight lantern.
