Introduction

The Ophir StarBright 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 StarBright 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, StarBright automatically identifies
the sensor type, calibration, and configuration. The user does not have to adjust anything.

The StarBright’s 320x240 full color screen enhances measurement readouts in ways that simple
monochrome displays cannot. The StarBright 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 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 StarBright at the touch of a button.

StarBright is capable of logging data onto a USB Flash Drive (Disk On Key), as well as real-time
reporting of data via USB to Ophir’s StarLab application to display and process the information.
StarBright has RS232 capabilities as well. StarBright also has the infrastructure for field upgrading
of the embedded software, should the need arise.

Above all, the StarBright 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.

StarBright’s User Interface is intuitive. The keypad functionality is context-sensitive and functions
according to the needs to the present screen. Where necessary, on-screen help is provided as well,
so you should not have to refer to this manual very often.
