PROBLEM TO BE SOLVED: To provide a high-mobility measuring device with reduced noise in a portion where the drift time is short in TOF method. SOLUTION: The high-mobility measuring device 10 comprises a means 12 of arranging an object to be measured which includes a probe which can be brought into contact with an electrode set up on the object to be measured, light irradiation means 14 of irradiating light on the object to be measured, voltage application means 16 for applying a voltage to the electrode via the probe, signal detection means 18 of detecting a current signal flowing in the object to be measured, and signal processing means 20 of processing a detection signal. The high mobility measuring device 10 performs measurement by the TOF method. This device 10 also includes a noise-reducing means which makes the light irradiation means 14 and other means (16 and 18) connected optically, and reduces the noise generated by the light irradiation means 14, by electrically separating and insulating the light irradiation means 14 from the other means; and a noise elimination means (20) for eliminating the noise from the light irradiation means which is mixed into the detection signal for the measurement by the TOF method.

PROBLEM TO BE SOLVED: To provide an apparatus for measuring anisotropy of a semiconductor film, which can measure carrier mobility values in two directions, i.e., vertical and horizontal directions of an organic thin film. SOLUTION: The apparatus 10 for measuring the anisotropy of the semiconductor film is equipped with a measurement object setting means 12 which has a probe contactable with an electrode disposed at an object to be measured; a light irradiation means 14 which irradiates the object to be measured with light; a voltage applying means 16 which applies a voltage to the electrode through the probe; a signal detecting means 18 which detects a current signal flowing in the object to be measured; and a signal processing means 20 for processing a detected signal. The measurement object setting means 12 includes three probes which can be positioned independently, and the voltage applying means 16 is made up such that the class of the voltage applied to each probe can be varied, and the measurement can be carried out in two kinds of measurement modes, i.e., a TOF method measurement mode and an FET method measurement mode.

PROBLEM TO BE SOLVED: To obtain a light source with known spectral absolute photon flux with a simple method. SOLUTION: Outgoing light of a spectral light source 100 having a lamp 1, converging optical systems (lenses) 2 and 4 and a spectroscope 3 is measured by a light detector 5 with a known quantum efficiency, and the spectral absolute photon flux of the spectral light source 100 is determined based on the measurement results. This light source is used as a light source with known spectral absolute photon flux. Calibration of a spectrometric device is performed by use of this light source with known spectral absolute photon flux to measure spectral characteristics of a light emitting element such as an OLED.

SOLUTION: This spectroscope 110 is equipped with an incidence slit 112, a collimator mirror 114 for turning light passing through the incidence slit 112 into parallel light, a diffraction grating 118 for receiving the parallel light from the collimator mirror 114 to output light at a different angle according to its wavelength, a first concave mirror 120 for turning output light from the diffraction grating 118 into parallel light, a second concave mirror 122 for condensing the parallel light from the concave mirror 120, and a light reception means 124 comprising a light reception surface 124a with the light condensed by the concave mirror 122 focused thereon. This spectroscope 110 is characterized in that spectrum measurement is performed by causing a dispersed light image of the incidence slit 112 to be focused on the reception surface 124a of the reception means 124.
