• 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.
• 82324B
The 82324B 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 82324B is a 3-wavelength sensor available for blue-ray optical disks,
DVD, and CD, and wavelengths ranging from 390 nm to 900 nm can be measured. It has a flat sensitiv-
ity characteristic especially 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 standard calibration wavelength is 405 nm. The calibration
wavelength addition option (650 nm: OPT82324B+22 or 780 nm: OPT82324B+23) can be added. Char-
acteristics in the blue light are optimized, and low reflectivity, low incident angle dependence, and low
polarization dependence are achieved. The 82324B has 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, this sensor is ideal for evaluating pickups and drives used for
the 3-wavelength type Blu-ray disc or HD DVD. The actual measurement value for wavelength sensi-
tivity correction is saved in the memory of each sensor.
When option 70 is specified, the following sensors for the TQ8210 and TQ8215 can be used:
• 82014A
The 82014A is a general-purpose, cylindrical-type sensor used for the TQ8210 and TQ8215. When this
sensor is used for the 8230, option 70 must be installed. Wavelengths ranging from 400 nm to 1100 nm
can be measured and the calibration wavelength is 850 nm. The typical value stored in the optical power
meter is used as wavelength sensitivity correction data.
