explosion
The latest optical power meter from Advantest Europe achieves accurate measurement of blue-violet lasers and higher output optical power for high-speed R/RW-CDs.
The latest optical power meter from Advantest Europe achieves accurate measurement of blue-violet lasers (400nm short wavelength laser) and higher output optical power for high-speed R/RW-CDs Optical media, that encompass DVDs and CDs, have evolved from being primarily for "ornamental use", to the higher data volume category of "recording use"

Testers boost mixed-signal SoC throughput
Advantest has released two new test systems aimed at mixed-signal SoCs: the T6683 has a top speed of 1GHz and up to 2048 test pins; the T6673 runs at up to 500MHz with a maximum of 1024 test pins
In order to achieve the required high-speed processing datarate, it is necessary to stabilise the high-speed optical laser output and maximise data writing capacity.
To accomplish this, semiconductor equipment manufacturers are being challenged to increase the accuracy of the optical laser output.
When combined with the Q82312 optical sensor, the Q8230 enables simple measurement of blue violet lasers.
The Q8230 also employs a 0.001dB resolution level and a 5.5-digit display as well as a function to adjust the wavelength setting in increments of 1nm This amounts to a tenfold improvement over the previous models, enabling the Q8230 to make accurate measurements of high-power analyser outputs at 200mW.
Moreover, in addition to analogue output, the Q8230 is fitted with a USB interface as standard, allowing for direct automatic download of digital data into a computer.
Through a series of technical advancements, the Q8230 achieves smooth data collection at the research level and an improvement of throughput for mass production.
Previous models employed complex procedures for measuring shorter wavelengths, including a need for additional instruments to adjust the photodiode resolution and to ones to regularly check and reset the wavelength range and power meter settings.
However, the Q82313's blue violet laser sensor is able to achieve constant monitoring over the 400nm shorter wavelength, allowing for a drastic improvement of throughput in mass production.
By improving the incident angle dependence and the maximum reflection rate of previous models, the new system is capable of highly accurate measurement at +/-2.5% correction wavelength.
The Q82313 high output laser sensor achieves 200mW power measurement, a fourfold improvement over previous models.
It is equipped with a diffuser to prevent a saturation of the photodiode.
This enables it to achieve the industry's leading measurement accuracy of 48x CD-R/RW and 8x DVD-R/-RW/+RW/RAM with +/-2.5% accuracy at (power) calibration wavelength.
