General Description
The Newport 1919-R is a microprocessor-based Laser Power/Energy Meter that provides a broad
range of measurements, displays, and data handling options. It operates with Thermopile,
Pyroelectric, and Photodiode sensors. Taking advantage of smart connector technology, it is easy-
to-use—simply connecting the sensor configures and calibrates the 1919-R to operate with that
sensor. The sensor configuration and calibration information is stored in an EEROM in the sensor
connector plug. This means that when the sensor is plugged in, 1919-R automatically identifies the
sensor type, calibration, and configuration. You do not have to adjust anything. Sensors are hot
swappable. Even after the meter is switched on, you can remove one sensor and insert a different
one. 1919-R will recognize the switch and reconfigure itself according to the settings of the new
sensor.
The 1919-R’s 320x240 full-color screen enhances measurement readouts in ways that simple
monochrome displays cannot. The 1919-R can graph power or energy versus time. It displays
power measurements in both digital and analog form simultaneously and also has a needle type
display. It will also autorange, so you do not have to set scales; or it can manual range if you wish.
It will remember what mode you were using before you turned it off and will return to that mode
when turned on. You can zoom in on the present reading, or subtract the background. Although
the calibration information is stored in the smart connector, you can recalibrate from the screen
and store the new calibration in the sensor. You can also zero the 1919-R at the touch of a button.
1919-R is capable of logging data onto a USB Flash Drive (Disk On Key), as well as real-time
reporting of data via USB to Newport’s PMManager application to display and process the
information. 1919-R has RS232 capabilities as well. 1919-R also has the infrastructure for field
upgrading of the embedded software, should the need arise.
Above all, the 1919-R has advanced circuitry and digital signal processing for excellent sensitivity,
signal-to-noise ratio, accuracy, and response time. It also has special circuitry to reject
electromagnetic interference.
1919-R’s User Interface is intuitive. The keypad functionality is context-sensitive and functions
according to the needs of the present screen. Where necessary, on-screen help is provided as well,
so you should not have to refer to this manual very often.
