Optical Power Meter


The 8230 is a handheld optical power meter, which is most suitable for R&D and production of LDs, optical pickups, and drives for optical disks.
Nine kinds of optical sensors with various purpose (general-purpose/blue-violet/high-power/three-wavelength) and different shapes (thin-type/cylindrical-type) are available. The three-wavelength optical sensors 82314B, 82324B and 82314BW are capable of measuring 405nm, 650nm, 780nm wavelength ranges. The blue-violet optical sensors 82312B and 82322B have realized a flat wavelength sensitivity characteristic and low dependency on an angle of incidence in the 405 nm range. The high-power optical sensors 82313B and 82323B enable high-power measurement of up to 200mW.
The main body that has 5 1/2 digits and 0.001dB resolution display can obtain measurement data easily by using the USB interface installed as standard.


Various sensors for next-generation optical disks
Most suitable sensors for Blu-ray disks in the 400nm range (82312B/82322B/82314B/82314BW/82324B)
Flat wavelength sensitivity characteristic (400nm to 420nm: ±1%typ.) It is not necessary to correct the individual difference in the laser wavelength.
Low incidence-angle-dependency for high NA pickup such as Blu-ray disk
Low polarization-dependency; small difference due to polarization of incident angle dependency, and high repeatability in laser and pickup measurements
Low reflection; less measurement deviation due to multi reflection between the sensor and the pickup
High-power sensor of up to 200mW (82313B/82323B).
Maximum light-receiving power of 200mW for pickup measurement of high-speed rewritable CD/DVD
It is possible to measure high power density without saturation up to 200mW even at 0.1mmφ spot diameter.
Low-price general-purpose optical sensor (82311B/82321B)
Highly reliable sensor that minimizes sensitivity deviation over time in the 400nm range
Both thin-type and cylindrical-type optical sensors are available. Manual measurement and system built-in measurement can be performed easily.
Sensor power calibration wavelength: 405/650/780nm for BD/HD DVD/DVD/CD with high accuracy under actual use conditions
Maximum three-wavelength power calibration is available on just one sensor by adding the calibration wavelength options. (405nm: OPT+21/650nm: OPT+22/780nm:OPT+23)
1nm-step wavelength sensitivity correction function
Guaranteed accuracy in the wide wavelength range (OPT+20 only for 82311B/82321B)
5 1/2 digits, 0.001dB resolution
Achieved the highest resolution for a handheld optical power meter. The wide dynamic range is highly-effective especially in automatic measurement using the USB interface.
USB interface as standard
OPT8230E+70 Optical power meter former-type sensor adaptive option.
This option enables the former-type sensors 820x series (82014A/82017A/Q82018A/82015) to be connected.

*The OPT8230E+11 is not available in combination with the OPT8230E+70.
