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 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.
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 (82314B/82324B/82314BW)
 
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 (82312B/82322B)
 
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 (82313B/82323B)
 
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 (82311B/82321B)
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.
