Abstract

PURPOSE: To obtain the Fabry-Perot type optical filter with small size and stably operated, capable of enlarging a passing wavelength variable range by constituting a cell of two pieces of mirrors for constituting a resonance circuit, and controlling a temperature of a substance packed in the cell.
CONSTITUTION: On the inside surfaces of two pieces of substrates 1a, 1b placed so as to be opposed to each other, mirrors 2a, 2b having a high reflection factor are provided. By these mirrors 2a, 2b and a spacer 3, a cell 4 being a closed space is formed, it is packed with a thermo-optical effect substance 5, and also, a heater 6 being a temperature control means for heating it is provided. In such a state, when a temperature of the substance 5 in the cell is varied by a temperature control means 6, a resonance condition of a light beam which is made incident roughly vertically on one of two pieces of mirrors, and wavelength of a light beam which passes through an optical filter is varied. In such a way, the optical filter becomes smaller in size and stably operated, and its passing wavelength can be varied to a comparatively large range.
