PHOTOMETRIC DEVICE AND PHOTOMETRIC METHOD

摘要

Provided is a photometric device with which rapid and highly precise measurements can be realized with a simple configuration. A photometric device (3) is provided with: a table (103) on which is placed a light-emitting diode (101) for emitting light radially; a probe needle (109) for supplying power to the light-emitting diode (101) and causing the light-emitting diode (101) to emit light; and a light-receiving module (1) for receiving the light emitted from the light-emitting diode (101) and measuring the quantity of light thereof. The table (103) has a substantially uniform plate-shaped reflector (103b) equipped with a reflection plane of a regular reflection surface, and the light-emitting diode (101) is placed on the reflection plane of the reflector (103b).
