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. 

● Blue-violet sensors to measure lasers of Blu-ray Disc　

To measure blue-violet lasers precisely, the 82312B and 82322B blue-violet sensors have realized a maximally flat wavelength sensitivity characteristic. This saves time in performing sensitivity correction at each measurement and always offers high-accuracy measurement results.

● Three-wavelength sensors to measure lasers with different wavelengths　  

The 82314B, 82324B and 82314BW sensors are capable of measuring all lasers of 405nm wavelength for Blu-ray Disc, 650 nm wavelength for DVD and 780nm wavelength for CD. In the range from 400 to 420nm wavelengths in particular, sensitivity correction is unnecessary because of the flat wavelength sensitivity characteristic. In other wavelength ranges, the wavelength sensitivity values stored in the sensor help easy operation.

● High-power sensors to measure high-power lasers for write　

The power output of a laser disc for write such as CD-RW exceeds 100mW at the peak even with a pickup installed. The 82313B and the 82323B are high-power sensors capable of measuring up to 200mW with high accuracy. These sensors have high linearity up to 200mW approximately even at beam spot of 0.1mm diameter.

● Low-priced and easy-to-use general-purpose sensors

The 82311B and the 82321B are low-price general-purpose sensors that can be used in a wide wavelength range from 390nm to 1100nm. The calibration wavelength is 780nm and the correction value is stored in the sensors. Sensitivity correction of other wavelengths is also available by using the options.

● Both thin types and cylindrical types

Two shapes of sensors can be selected for each purpose. Thin types of sensors are convenient for measuring optical power in a limited space with a pickup installed, and cylindrical types of sensors are used for measuring the output power from a fiber with an optical bench.
