General Information
1.1 System Overview
The 1830-C Optical Power Meter is a ±20,000 count A/D resolution, auto-
ranging picoammeter. Measurements are displayed on a large 4
1
/2 digit
liquid crystal display (LCD) and can also be taken remotely via the RS-232C
port or the IEEE 488 GPIB bus. The 1830-C is designed to take continuous
wave optical power measurements and is compatible with all of Newport’s
Low-Power Semiconductor photodetectors. A family tree of the 1830-C
compatible detectors and accessories is shown in Figure 1 below.

Figure 1. 1830-C Power Meter and Compatible Detectors
Detectors connect to the 1830-C through a calibration module, in which the
responsivities and other information unique to the detectors is stored.
Calibration modules are ordered with the detectors at the time of purchase
and are labeled with the detectors’ model number and serial number.
Detectors with calibration modules have a “/CM” appended to their model
number.
EXAMPLE: 818-SL (no calibration module)
