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.
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.
