Abstract
An optical calibrating apparatus includes: a laser illuminator (6) disposed in an eccentric adjusting sleeve (5), an inner inclined adjusting sleeve (4) within a jacket (3), an outer inclined adjusting sleeve (2) outside the jacket (3), and a cylindrical casing (1), in which a laser line is emitted by the illuminator (6) for checking levelling, plumbing and verticality and the laser line has been calibrated for a horizontality or a verticality by rotating the eccentric adjusting sleeve (4), the inner and outer inclined adjusting sleeves (4, 2) until the emitted laser line is aligned with a standard laser line emitted from a standard optical calibrator or aligned with a mark preset by a standard instrument.
Claims8
An optical calibrating apparatus comprising:
- a casing (1) having a hollow cylinder (11) mounted on a base (7) and defining a front chamber (C1) in a front portion and a rear chamber (C2) in a rear portion of said casing (1);
- an outer inclined adjusting sleeve (2) rotatably engageable in the front chamber (C1) of the casing (1);
- a jacket (3) disposed within said outer inclined adjusting sleeve (2) having a lens mounted on a front portion of the jacket (3);
- an inner inclined adjusting sleeve (4) rotatably engageable in said jacket (3);
- an eccentric adjusting sleeve (5) rotatably engageable within said inner inclined adjusting sleeve (4);
- and
- a laser illuminator (6) operatively emitting a laser light outwardly through said lens on said jacket (3) for an optical calibration, with said laser illuminator (6) rotatably engageable within said eccentric adjusting sleeve (5), whereby upon rotation of either of said sleeves (2, 4, 5) and said illuminator (6) to allow the light as emitted from said illuminator (6) to be matched with a standard mark as preset from a standard calibration instrument, said sleeves (2, 4, 5) and said illuminator (6) are stably fixed in said casing to form a laser instrument as an optical calibrating apparatus for emitting a datum laser light for calibration use.
