Optical Power Meter
8230E
Optical power meter suitable for R&D and production of optical disks
The 8230E is a low-priced handheld optical power meter, which is most suitable for production of LDs, optical pickups and drives for optical disks. Two kinds of general-purpose sensors and two kinds of high-output sensors with different shapes respectively (thin-type/cylindrical-type) are available. The high-power optical sensors 82313B and 82323B are capable of high-power measurement up to 200 mW. The main body that has 4½-digits and 0.01 dB resolution display can obtain measurement data easily by using the USB interface installed as standard.
● 4 ½-digit display
● Low-priced general-purpose sensors and high power sensors are
available
● USB interface
USB interface
In addition to an analog output, the 8230E is equipped with a USB interface. Consequently, it can collect digital data directly from the PC side without an additional GPIB interface, which results in cost reduction in mass production lines.
Four types of optical sensors to meet various applications
● 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.
● 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.
Applicability table for the four product types of sensors
| Shape | Part Number | Wavelength Range | Calibration Wavelength |
Power Range | Light Receiving Area | |
| General-purpose | Thin | 82311B | 390 to 1100 nm | 780 nm | 1 nW to 50 mW | Approx. 9.5 mm × 9.5 mm |
| Cylinder | 82321B | 390 to 1100 nm | 780 nm | 1 nW to 50 mW | Approx. 8.5 mmφ | |
| High-power | Thin | 82313B | 390 to 1100 nm | 650 nm | 10 nW to 200 mW | Approx. 8.5 mmφ |
| Cylinder | 82323B | 390 to 1100 nm | 650 nm | 10 nW to 200 mW | Approx. 8.5 mmφ |
*In addition to the calibrated wavelength indicated, calibration with additional wavelengths (405, 650, 780 nm) is possible as an option.
*The wavelenght sensitivity of the 82311 and the 82321 is corrected by using the typical values. As for the 82311, correction by measurement is possible as an option.
