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) |
