[Problem] To measure the temperature distribution in a heating furnace. [Solution] An in-furnace heat quantity measuring element 10 is formed of quartz and has a rectangular parallelepiped shape. The element has a width of 4 mm × a length of 3 mm × a height of 2 mm. Five through holes 11-15 each having a circular cross section are formed in parallel with the side surfaces, the upper surface, and the bottom surface, near the center in the width direction and the thickness direction. The diameter D of the cross sections of the through holes is 0.2 mm. The in-furnace heat quantity measuring element is placed in a heating furnace, and is softened when heated, and the through holes are deformed by the action of surface tension to reduce the diameter D. The deformation quantity of the diameter D has a strong correlation with the heat quantity received by the in-furnace heat quantity measuring element 10. Therefore, by using the in-furnace heat quantity measuring element 10, the heat quantity received by the in-furnace heat quantity measuring element 10 by heating can be measured at an arbitrarily defined place in the heating furnace. When the temperature profile is known, the heat quantity can be further converted into a temperature, and the temperature distribution in the heating furnace can be measured.

An optical component including an interference filter which is less likely to generate back reflected light, where the filter is accommodated in a hollow cylindrical housing and is tilted with respect to the optical axis. The housing has front and back openings. First and second collimator lenses respectively face the front and back openings. The housing includes a filter housing section and first and second cylindrical optical path sections extending in the front-back direction respectively from the front and back openings to the filter housing section while maintaining the shape of each opening. The diameter of the opening of the first optical path section is smaller than the apparent diameter of the first collimator lens.

A variable optical attenuator in which a polarization beam splitter splits a beam incoming from the front into two linearly-polarized beams perpendicular to each other and separately outputs them to the back along first and second light paths. A Faraday rotator rotates a polarization plane of the two incoming linearly-polarized beams to an arbitrary angle by controlling a magnetic field to be applied to a Faraday element by a magnetism applying means and outputs them to the back. First and second analyzers arranged in the first and the second light paths and parallelly arranged perpendicular to these light paths are arranged in that order. The two analyzers have optical axes perpendicular to each other so that the optical axes are in the same direction as that of the polarization plane of the two linearly-polarized beams output from the polarization beam splitter.

An input/output port, a birefringent element, variable polarization rotator, and a reflector are arranged along an optical axis in the order named. The variable polarization rotator includes permanent magnets for applying a fixed magnetic field to a Faraday rotator in an in-plane direction to magnetically saturate the Faraday rotator and a solenoid coil for applying a variable magnetic field to the Faraday rotator in a direction of the optical axis. A fixed magnetic field is applied in the <211> direction, in which the Faraday rotator is likely to be magnetically saturated. The Faraday rotator can be saturated with a low magnetic field of about 100 Oe. The permanent magnets may employ ferrite permanent magnets, which have weak magnetic forces. A variable magnetic field may also be reduced. Therefore, an air-core coil can be used.
