User Detector Compatibility
The 1931-C/2931-C Series Power Meters are compatible with Newport's new
918D, 918L and legacy 818 Series Low Power Detectors. When using an 818/CM
Series Low-Power Detector, a 841-DIN adapter is required for compatibility with
the DB-15 connector of the power meter. When using an 818 Series Low-Power
Detector, originally purchased without a calibration module, an 818-SCAL-OPT or
RCAL-10 calibration module is required for calibrated readings using the power
meter. Please contact a Photonics Application Support Engineer for
assistance with selecting the appropriate adapter.
