meter together with this manual.
1.1 Product Outline
The 82311B, 82313B, 82321B, and 82323B are optical sensors used for the 8230, 8230E, and 8250A optical
power meters.
The 82312B, 82314B, 82314BW, 82322B, and 82324B are optical sensors used for the 8230 and 8250A opti-
cal power meters.
• 82311B
The 82311B thin-type, general-purpose optical sensor is available for measurement in optical disk
equipment or narrow spaces. Wavelengths ranging from 390 nm to 1100 nm can be measured and the
standard calibration wavelength is 780 nm. The calibration wavelength addition option (405 nm:
OPT82311B+21 or 650 nm: OPT82311B+22) can be added.
For the standard model, the typical value for wavelength sensitivity correction is saved in the memory
of the sensor. The actual measurement value for the sensor-specific wavelength sensitivity correction
can be acquired by specifying the wavelength sensitivity correction option (OPT82311B+20).
• 82321B
The 82321B cylindrical-type optical sensor is available for attachment to test equipment, for measure-
ment on an optical bench, or for optical fiber system measurement. Adapters to accommodate each op-
tical connector are available. Wavelengths ranging from 390 nm to 1100 nm can be measured and the
standard calibration wavelength is 780 nm. The calibration wavelength addition option (405 nm:
OPT82321B+21 or 650 nm: OPT82321B+22) can be added.

• 82312B
The 82312B thin-type optical sensor is available for measurement in optical disk equipment or narrow
spaces. The 82312B is available for blue-ray optical disks and has a flat sensitivity characteristic for
wavelengths ranging from 400 nm to 420 nm. Therefore, even if the wavelength of the light source is
different, a highly accurate measurement can be performed without wavelength sensitivity correction.
The calibration wavelength is 405 nm. The actual measurement value for wavelength sensitivity correc-
tion is saved in the memory of each sensor.
