    Abstract: A wavelength tunable filter (200) selectively transmitting light of any desired wavelength within the range of 450 nm to 1100 nm without using a band pass filter is disclosed. The wavelength tunable filter (200) comprises a plurality of polarizers (101a to 101f) and a plurality of units between the adjacent polarizers (101 a to 101f) on a common optical axis (111) in a housing (201). Each unit has, in order from light incident side, a quartz birefringent plate (102), an ultra-wide band 1/4 waveplate (103) and an ultra-wide band 1/2 waveplate (104). The ultra-wide band 1/2 waveplate (104) is accommodated in a cylindrical rotatable body (303; 403; 503) and it is rotated by a rotating mechanism.

    Abstract: An optical device includes a waveplate sandwiched between first and second polarizers and is arranged to receive light emanating from an object or object image that is in motion relative to the optical device. A detector array includes one or more detector elements and is optically coupled to receive light from the second polarizer. Each detector element of the detector array provides an electrical output signal that varies according to intensity of the light received from the second polarizer. The intensity of the light is a function of relative motion of the object or the object image and the optical device and contains spectral information about an object point of the object.

    Abstract: A spectrometric analyzing device is capable of analyzing a thin film with high accuracy by using light having an arbitrary wavelength, such as not only infrared light but also visible light, ultraviolet light and X-ray, and using whatever refractive index of a supporting member of the thin film. A spectrometric analyzing device comprises a light source (1), a polarizing filter (2), a detection unit (3), a regression operation unit (4) and an absorbance spectrum calculation unit (5). The light source (1) emits light at n different angles of incidence (θ n ) to a measurement portion. The polarizing filter (2) shields an s-polarized component. The detection unit (3) detects transmitted spectra (S). The regression operation unit (4) uses the transmitted spectra (S) and a mixing ratio (R) to obtain an in-plane mode spectrum (s ip ) and an out-of-plane mode spectrum (s op ) through a regression analysis. The absorbance spectrum calculation unit (5) calculates an in-plane mode absorbance spectrum (A ip ) and an out-of-plane mode absorbance spectrum (A op ) of the thin film, based on the results from a state in which the thin film is on the supporting member and a state in which no thin film is on the supporting member.
