PSR-1100 Manual

1 Introduction

This manual contains data concerning the PSR-1100 field-portable spectroradiometer system. The system consists of a UV-visible-NIR range spectrometer with integrated lens (or optional fiber optic input) that produces output calibrated to units of spectral radiance (W/m illumination source by way of the lens. The spectrometer is a dispersive PDA system operating in the range of 320–1100 nm with a 512-element array detector.

All electronics for controlling the PSR-1100 system operation are built into the instrument. The instrument incorporates manual controls and on-board storage for selfcontained field operation, as well as the capability to connect to a host computer system using the provided application software via USB or Bluetooth communications interface. The instrument is powered by a Li-Ion battery pack (provided with each system).

The PSR-1100 contains an internal microprocessor that controls the data acquisition of the detector array, the communication interface to the host PC, and provides data storage. Calibration data and spectral data (collected in standalone mode, described below) are stored in flash memory. The PSR-1100 has a built-in shutter for automatic dark measurements. The dark current data are retained in RAM and the microprocessor automatically performs mathematical functions on collected spectral scan data, including dark subtraction and automatic integration adjustment.

2 Hardware and Interface Description

2.1 Part Identification

2.1.1 Spectrometer

The spectrometer component of the SR-1100 is a crossed Czerny-Turner configuration using a ruled grating as the dispersive element. Energy enters the spectrometer and is collimated before being reflected off the grating and refocused onto the PDA detector. The detector is a 512-element array, covering the spectral range 320–1100 nm. The spectrometer and controlling electronics are contained in the housing.

2.1.2 Battery Pack

The PSR-1100 uses a Li-Ion battery pack as a power source, supplied with the system. The Li-Ion battery runs at a nominal 7.4V and is designed to provide more than 3 hours operation following a full charge. When the battery voltage falls too low to power the instrument, it will turn off and go to 0 volts. Remove the battery from the instrument for recharging with the supplied charger. Refer to Section 0:

Battery Charger for charging details.

2.1.3 Optical Input

The PSR-1100 comes with a standard fixed 4° field-of-view lens foreoptic installed. Custom configurations may replace the lens with alternate foreoptics such as a 25° FOV fiber optic input.

The entire spectrometer/foreoptic system is factory-calibrated for radiance using a NIST-traceable source. The calibration coefficients are stored in flash memory by the internal microprocessor. The application software retrieves these coefficients and applies them to acquired scan sample data to convert to radiometric units.

2.1.4 Serial Communications

Communications with the PSR-1100 are conducted using USB or Bluetooth.

USB communications require a standard cable with USB-B connector to fit the receptacle on the control panel. The first time the host PC is connected to the instrument, Windows® will need to install drivers for the virtual COM port functionality. These drivers are included on the CD-ROM that was provided with your unit. Once the drivers are loaded, the provided Windows® application software interacts with the spectroradiometer using a virtual COM port in the same fashion as a standard RS-232 serial port (115200 baud, 8 data bits, 1 stop bit, no parity).

The PSR-1100 is also enabled for wireless communications with the application software provided the user has installed a Bluetooth serial port on the host PC. Depending on your Bluetooth adapter’s configuration utility, you will need to enter an identifier for your instrument type (typically called its PIN key or pairing code) the first time you use your PSR-1100. This code is “psr1100”. Your Bluetooth utility will recognize the instrument by a unique name with the syntax “PSR-1100 ####”, where #### is replaced by the serial number of the unit.

2.1.5 Front Panel

The front panel of the PSR-1100 contains the on/off switch, USB connector, battery receptacle and a control panel with membrane switches and LCD display. A handstrap is permanently attached and near the front panel are two mounting brackets for attaching a shoulder strap. See Section 3: Control Panel for more information.

2.1.6 Back Panel

The opposite end of the PSR-1100 contains the optical input (lens or SMA fiber optic input), Bluetooth antenna and optional tripod mount.

2.1.7 Laser Scan Switch

The Laser Scan switch is located on the top cover of the spectroradiometer. Depressing the switch actuates the sighting laser and can be optionally configured to initiate the start of a standalone spectral scan.

DANGER: DO NOT LOOK INTO THE LASER BEAM AT ANY TIME, INCLUDING INSTRUMENT SETUP OR OPERATION.
