UV/Si Calibrated Photodetectors
IRVINE, Calif., March 6, 2012 — Newport Corp. has introduced the 818-ST2 and 818-ST2-UV wand photodetectors. Designed with protective aluminum housing, they operate from 200 to 1100 nm.
Specifications are identical to the company’s legacy 818-ST and 818-ST-UV series, which will be phased out in four months. Sturdy metal cases for both new products are designed to safeguard the optics in the setup, especially in the UV wavelength range, and to keep the housing and attenuator glue protected from high heat damage.
The 818-ST2 incorporates a 10 × 10-mm silicon photodiode. The slender wand design is suitable for detection and measurement in tight or confined spaces with a convenient mounting hole on the side, making it easy to mount without the need for angle brackets.
Power levels are from picowatts to 2 W, with a built-in calibrated OD3 attenuator that has an easily readable and accessible on/off indicator. The DB15 calibration module is detachable from the BNC connector, permitting convenient interface with the company’s power meters, including models 1830-R-GPIB, 1916-R, 1917-R, 1918-R, 1928-C and 1936-R/2936R.
The 818-ST2 and 818-ST2-UV also are compatible with oscilloscopes and current meters.
