摘要： A Fourier transform type spectrophotometer capable of stably controlling a speed of a moving mirror comprises a movable unit to which a moving mirror is fixed, outside-force-applying means configured to apply external force larger than movement resistance of the movable unit to the movable unit, a driving source configured to apply positive or negative driving force along the moving direction of the movable unit to the movable unit, a speed measurement unit configured to measure the speed of the movable unit, and a driving force control unit configured to control the driving force of the driving source so that the movable unit is moved in a predetermined manner based on the, wherein a rate of fluctuation of the driving force is suppressed by operating in a state in which the driving force of the driving source is high due to the external force to thereby stabilize the control.

摘要： An infrared light source device includes: a heater portion which emits infrared light by being heated; and a cover member arranged to cover an entire circumference of the heater portion without contacting the heater portion, and having a hole formed therein for emitting the infrared light from the heater portion to outside. A material for the cover member is a pure aluminum (an aluminum alloy with a purity of 99% or more), which has a high heat reflectivity and is less likely to be denatured by heat dissipation from the heater portion.

摘要： A Fourier transform spectroscope having a control interferometer capable of facilitating optical axis adjustment and miniaturization by reducing the number of optical elements. Using a first reflection mirror provided with a reflection surface configured to reflect measurement light emitted from a measurement light source toward a beam splitter and a first through-hole extending along an optical axis direction of the measurement light reflected on the reflection surface and a laser light source holding portion configured to hold a laser light source such that laser light emitted from the laser light source is incident to the beam splitter through the first through-hole, optical axes of the measurement light and the laser light are aligned with each other.
