摘要： In a calibrator used for a non-destructive transmission optical measuring apparatus for quantitatively determining a specific component contained in a measuring object by making light incident on the measuring object at its light-incident area, detecting the light having entered, and having been transmitted through, the interior of the measuring object, at its light-emergent area set at a position different from the light-incident area, and measuring absorption of the light to quantitatively determine the specific component contained in the measuring object, the calibrator comprises a closed body having a light inlet and a light outlet, the interior of which is provided with a substrate having light absorption characteristics identical or similar to those of the specific component, and in which a light path length from the light inlet to the light outlet is so set as to be equal or substantially equal to an effective light path length of the light transmitted through the interior of the measuring object. This calibrator can make calibration on the non-destructive transmission optical measuring apparatus without destroying measuring objects and in a high precision and a good reproducibility and also in a simple way and short time.

摘要： A bidirectional optical module having a device 1 for emitting transmitting signal light, an optical fiber 8 which the transmitting signal light from the device enters, a light-receiving device 9 which light from the optical fiber enters, and a wavelength splitting filter 4. The transmitting signal light emitted from the device is sent forward through the optical fiber, and the receiving signal light is received through the optical fiber. The bidirectional optical module has an optical device (optical isolator) of a reflection polarizer 6 bonded to an end face of the optical fiber, a Faraday rotator 5 disposed integrally on the reflection polarizer and an absorption polarizer 3 disposed on an optical path extending between the device and the filter. The reflection polarizer has a wavelength dependency which functions as a polarizer for the transmitting signal light, but does not function as a polarizer for the receiving signal light.
