• 82322B
The 82322B 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. The 82322B 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 sensitiv-
ity correction. The calibration wavelength is 405 nm. The actual measurement value for wavelength sen-
sitivity correction is saved in the memory of each sensor.
• 82313B
The 82313B thin-type optical sensor is available for measurement in optical disk equipment or narrow
spaces. The 82313B is ideal for measuring optical disk equipment in which a high power laser diode
(LD) is used. If the light condenses on the incident surface, up to 200 mW of optical power can be mea-
sured without saturation. Wavelengths ranging from 390 nm to 1100 nm can be measured and the stan-
dard calibration wavelength is 650 nm.
The calibration wavelength addition option (405 nm: OPT82313B+21 or 780 nm: OPT82313B+23) can
be added. The actual measurement value for wavelength sensitivity correction is saved in the memory
of each sensor.
• 82323B
The 82323B 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. The 82323B is ideal for measuring optical disk equipment in which a high
power laser diode (LD) is used. If the light condenses on the incident surface, up to 200 mW of optical
power can be measured without saturation. Wavelengths ranging from 390 nm to 1100 nm can be mea-
sured and the calibration wavelength is 650 nm. The calibration wavelength addition option (405 nm:
OPT82323B+21 or 780 nm: OPT82323B+23) can be added. The actual measurement value for wave-
length sensitivity correction is saved in the memory of each sensor.
• 82314B/ 82314BW
The 82314B and 82314BW thin-type optical sensors are available for measurement in optical disk
equipment or narrow spaces. The 82314B and 82314BW are 3-wavelength sensors available for blue-
ray optical disks, DVD, and CD, and can measure wavelengths ranging from 390 nm to 900 nm. They
have a flat sensitivity characteristic especially for wavelengths ranging from 400 nm to 420 nm. There-
fore, even if the wavelength of the light source is different, a highly accurate measurement can be per-
formed without wavelength sensitivity correction. The standard calibration wavelength is 405 nm. The
calibration wavelength addition option (650 nm: OPT82314B+22 and OPT82314BW+22, or 780 nm:
OPT82314B+23 and OPT82314BW+23) can be added. Characteristics in the blue light are optimized,
and low reflectivity, low incident angle dependence, and low polarization dependence are achieved. The
82314B and 82314BW have sufficient sensitivity in the 650-nm band used for DVD and in the 780-nm
band used for CD. Because blue-ray optical disks, DVD, and CD can be measured without replacing the
sensor, these sensors are ideal for evaluating pickups and drives used for the 3-wavelength type Blu-ray
disc or HD DVD. The actual measurement value for wavelength sensitivity correction is saved in the
memory of each sensor.
The 82314BW is designed by expanding the light receiving area (10 mm x 10 mm) of the 82314B into
an area (18 mm x 18 mm) and the output light from the high NA lens can be measured easily and stably.
