Title: Variable light attenuator having rotating light-attenuating disc built-in
Inventor: GOTOU AKIYA
IPC: G02B5/00
Filed: 1979-03-16
Abstract: PURPOSE:To variably obtain a necessary quantity of light attenuation with a low insertion loss over a wide range by specifying the structure of a variable light-attenuating plate. CONSTITUTION:In a peripheral portion of a glass disc with both sides optically polished, notch 6 whose length is half or less of the disc radius is made toward the disc center. An aluminum vacuum-deposited film is formed on the disc surface while continuously changing the deposition thickness along the rotating direction from the extension line of one side of notch 6, as a starting line, allowed to coincide with the disc diameter, producing variable light-attenuating plate 3. While inserting plate 3 between rod lenses 2, 4, rotating shaft 7 of servomotor 8 or the like is attached to the central opening of plate 3. When notch 6 of plate 3 is between lenses 2, 4, an insertion loss due to plate 3 becomes zero, and the optical loss between incident and emergent optical fibers 1, 5 corresponds only to a loss due to bonding to lenses 2, 4.
