Abstract: There is provided a tunable filter with a wavelength monitor, that comprises a wavelength selector 3, a separator for separating a part of a transmitted light beam or a reflected light beam when a wavelength is swept by the wavelength selector, and a monitor 6 for monitoring a part of the separated light beam.

Abstract: A tunable filter includes a polarizer, a polarization rotator, a diffraction grating and a diffraction grating adjustor. The polarizer polarizes a light beam and splits the light beam into first and second light beams. The polarization rotator rotates a plane of polarization of the first light beam at 90° to generate a rotated light beam. The diffraction grating receives the rotated light beam and the second light beam. The diffraction grating adjustor adjusts the diffraction grating to change incident angles of the rotated light beam and second light beam.

Abstract: An engraving head that includes a movement mechanism for moving an engraving stylus within the body housing of the engraving apparatus is provided. The movement of the engraving stylus causes the tip of the engraving stylus to approach and recede from an engraving surface. The movement mechanism contains a movable body and a first energizing means. The movable body moves in association with a movement space member's inner circumference. The movement space member is positioned inside the body housing. The first energizing means is employed to energize the movable body in a direction away from the engraving surface. Additionally, a second energizing means serves to energize the movable body in a direction towards the engraving surface against the opposing energizing force of the first energizing means. The second energizing means may be, for example, compressed gas. As the movable body travels downward towards the engraving surface, the tip portion of the engraving stylus also approaches the engraving surface.
