Bench-type optical power meter suitable for R&D and production of optical disks
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 0.001 dB resolution and 5½-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 405 nm, 650 nm, 780 nm 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 200 mW.
Furthermore, the optical sensors for the TQ8210/TQ8215 series are also usable.
Ideal for making automated systems
The 8250A is an optical power meter optimal for building up automated production lines of Blu-ray Disc, DVD, CD and other optical pickups.
It is equipped with USB and GPIB interfaces as standard, which allows easy establishment of automated systems.
In addition, the latest USB driver is available from our website to make your operation easier.
The GPIB commands are compatible with those of the former model TQ8215.
By adopting low-noise design and a high-resolution A/D converter, The 8250A achieves measurement with a high resolution of 0.001 dB that never overlooks subtle change.
