摘要:
To provide an electrostatic actuator, etc. which is capable of miniaturizing the size, and preventing moisture, etc. from entering a gap in an effective manner. An electrostatic actuator includes an electrode substrate 10 having individual electrodes 12 as fixed electrodes, and a cavity substrate 20 having diaphragms 22 as movable electrodes which are disposed so as to be opposed to the fixed electrodes 12 with a predetermined distance, and operated due to an electrostatic force occurring between the cavity substrate 20 and the individual electrodes 12. Sealing portions 26a are formed on one of the electrode substrate 10 and the cavity substrate 20, each of the sealing portions 26a has a plurality of sealing layers (a TEOS layer 25a, a moisture permeation preventing layer 25b) laminated one another, and each of the sealing layers is made of a sealing material 25 for isolating a space formed between the individual electrode 12 and the diaphragm 22.

摘要:
A wavelength-variable interference filter includes first and second electrodes provided at first and second substrates, respectively, the second substrate including a movable section, first and second electrode wires that extend from the first and second electrodes toward outer circumferential edges of the first and second substrates, respectively, a first opposite electrode wire disposed so as to be isolated from the second electrode, and a first conductive section that connects the first electrode wire with the first opposite electrode wire. The second electrode wire and the first opposite electrode wire extend passing through a center point of an imaginary circle of the movable section in respective directions and dividing the imaginary circle at regular angular intervals.
摘要:
An Etalon filter includes a first substrate, a second substrate which faces the first substrate, a first optical film which is provided on the first substrate, and a second optical film which is provided on the second substrate to face the first optical film. The reflective characteristic of the first optical film determined by the reflectance of light of each wavelength in a reflective band is different from the reflective characteristic of the second optical film determined by the reflectance of light of each wavelength in the reflective band. The first optical film can have a reflective characteristic with a first wavelength λ1 as a center wavelength, and the second optical film can have a reflective characteristic with a second wavelength λ2 different from the first wavelength as a center wavelength.
