The 8250A is a bench-t*e 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-di* display and is also quipped with GPIB and U* 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-t*e/ cylindrical-t*e) 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-di* display 

 * GPIB and U* 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-t*e and cylindrical-t*e 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)&
