Advantest Corp. has released its Q8230 optical power meter that achieves accurate measurement of blue-violet lasers and higher output optical power for high-speed R/RW-CDs.

When combined with the Q82312 optical sensor, the Q8230 enables a simple measurement of blue violet laser. The product employs a 0.001dB resolution level and a 5.5 digit display, as well as a function to adjust the wavelength setting by increments of 1nm. This amounts to a 10 times improvement over the previous models, enabling the Q8230 to make accurate measurements of high-power analyzer outputs at 200mW.

Equipped with a diffuser to prevent a saturated status by photo diode, the power meter enables measurement accuracy of 48x CD-R/RW and 8x DVD-R/-RW/+RW/RAM with 2.5 percent accuracy at calibration wavelength.

The device is also fitted with a USB interface as standard equipment, allowing for direct automatic installation of digital data into the computer. Further, it has an analog output of 0V to 2V.
