Optical components

Abstract

To provide an optical component that can prevent dirt from adhering to the optical element. [Solution] The optical component 2 includes a non-magnetic chamber 4 having a first end 4a for receiving light and a second end 4b for sending out light, a holder 6 that holds an optical element 14 housed in the chamber 4, a first magnetic coupling 8 connected to the holder 6, a second magnetic coupling 10 disposed outside the chamber 4 and linked to the first magnetic coupling 8, and a drive shaft 12 connected to the second magnetic coupling 10. The optical element 14 is driven by the rotation of the drive shaft 12.

Claims

1. It is an optical component, An optical component comprising: a non-magnetic chamber having a first end for receiving light and a second end for transmitting light; a holder for holding an optical element housed within the chamber; a first magnetic coupling connected to the holder; a second magnetic coupling disposed outside the chamber and interlocking with the first magnetic coupling; and a drive shaft connected to the second magnetic coupling, wherein the optical element is driven by the rotation of the drive shaft.

2. The optical component according to claim 1, wherein a motor is connected to the drive shaft.

3. The optical component according to claim 1, wherein the non-magnetic material includes aluminum, stainless steel, copper, brass, resin, glass, or ceramics.

4. The optical component according to claim 1, wherein the chamber is filled with dry air or an inert gas containing nitrogen gas, or the pressure is reduced.

5. The optical component according to claim 1, wherein the first end and the second end of the chamber are connected to each other by a connecting portion.
