品牌:日本爱德万 | Advantest | ADCMT Overview The 8250A is a bench-type optical power meter, which is most suitable for R&D and production of LDs, optical pickups, and drives for optical disks.

It has 0.001dB resolution and

5 1/2-digit display and is also quipped with GPIB and USB interfaces as standard, allowing easy automated system establishment. 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 82314A, 82324A and 82314W are capable of measuring 405nm, 650nm, 780nm wavelength ranges. The blue-violet optical sensors

82312 and

82322 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

82313 and

82323 enable high-power measurement of up to 200mW. Furthermore, the optical sensors for the TQ8210/TQ8215 series are also usable. Features * High resolution 0.001dB,

5 1/2-digit display * GPIB and USB interfaces * Various sensors available by use 1) three-wavelength optical sensor applicable to Blu-ray disk, DVD (650nm) and CD (780nm), most suitable for pick up evaluation (82314A/82324A/82314W) - Flat wavelength sensitivity characteristic and low dependency on an angle of incidence in the 405/650/780 nm bands - Low reflection;

less measurement deviation due to multi reflection between the sensor and the pickup. 2) Blue-violet optical sensor most suitable for Blu-ray disk in the 405nm band (82312/82322) - Flat wavelength sensitivity characteristic and low incident-angle-dependency in the

405 nm band - Low reflection;

less measurement deviation due to multi reflection between the sensor and the pickup 3) High-power optical sensor of up to 200mW (82313/82323) - The maximum light-receiving power of 200mW suitable 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. 4) Low-price general-purpose optical sensor (82311/82321) * 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 - 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) * The optical sensors for the TQ8210/TQ8215 series (82014A/82017A/82015/Q82018A) are also usable.
