摘要： The invention relates to a spectrophotometer having a light source capable of alternatively producing near infrared radiation and another radiation other than the near infrared radiation, a dispersing section for dispersing radiation from the light source to provide substantially monochromatic radiation so that a sample is irradiated with the substantially monochromatic radiation to thereby provide sample radiation, and a sensing section for sensing the sample radiation. The sample radiation is subjected to energy absorption of a specific wavelength by the sample. The sensing section includes a first sensing unit having a near infrared radiation sensor, a second sensing unit having a visible/ultraviolet radiation sensor and a temperature control unit for holding the near infrared radiation sensor at a substantially constant temperature lower than the room temperature.

摘要： Light irradiated to a sample is detected by a detector in order to measure the optical properties of the sample. The image of a minute virtual light source for the light is focused in the neighborhood of the measuring face of the sample by a first optical system arranged between the light source and the sample. The light outgoing from the sample is incident to the detector by way of a second optical system arranged between the sample and the detector and having conjugate points in the neighborhood of the measuring face of the sample and of the light receiving point of the detector.

摘要： A spectrophotometer having functions of both of a double-monochromator and a single-monochromator including a light source, a first spectroscope having a first slit through which light from the light source passes and a first dispersion element for dispersing the light from the first slit, a second spectroscope having a second slit for receiving light dispersed from the first dispersion element for dispersing the light from the second slit, and a third slit for receiving the light dispersed from the second dispersion element. A sample compartment is provided for transmitting the light from the first dispersion element or from the third slit directly to a detector or through a sample to the detector. An optical unit is provided for changing transmitting light paths between a first light path for transmitting the light from the first dispersion element to the sample compartment through a fourth slit and a second light path for transmitting the light from the third slit to the sample compartment. A length of a light path from the first dispersion element to the second slit is equal to a length of a light path from the first dispersion element to the fourth slit.
