  • Page 7: Chapter 1: Introduction

    New features consist of the 3648-element detector with shutter, high-speed electronics, and interface capabilities to Linux, Macintosh and Windows operating systems. The USB4000 is responsive from 200-1100 nm, but the specific range and resolution depends on your grating and entrance slit selections.

    Modular Light Sources and Sampling Accessories Ocean Optics offers a complete line of spectroscopic accessories for use with the USB4000. Most of our spectroscopic accessories have SMA connectors for application flexibility. Accordingly, changing the sampling system components is as easy as unscrewing a connector and replacing an accessory. Available accessories include the following: •...

  • Page 10: Interface Options

    Interface Options The USB4000 has both USB and serial port connectors (with the use of an adapter), enabling you to connect the spectrometer to a computer via a USB or serial port. However, you must create custom software if using the serial port. SpectraSuite software is available if you are connecting via the USB port.

    4. Insert the rectangular end of the cable into the USB port of the computer. If you installed SpectraSuite prior to connecting the USB4000, the SpectrSuite installs the USB4000 drivers. If the drivers do not successfully install (or if you connected the USB4000 to the computer before installing SpectraSuite), consult Chapter 3: Troubleshooting.

  • Page 14: Serial Port Mode

    1. Connect the serial cable adapter block to the appropriate pins of the USB4000’s 22-Pin Accessory Connector. 2. Connect one end of the 9-pin serial cable to the adapter block on the USB4000, and then connect the other end to a serial port on the computer.

    SpectraSuite Installation Windows Operating Systems If you connected your Ocean Optics USB4000 device to the computer prior to installing your Ocean Optics software application on a Windows platform, you may encounter installation issues that you must correct before your Ocean Optics device will operate properly.

  • Page 16: Remove Improperly Installed Files

    The system is now able to locate and install the correct drivers for the USB device. Mac Operating Systems Since there are no device files for the USB4000 Spectrometer in a Mac operating system, you should not encounter any problems if you installed the spectrometer before the SpectraSuite software.

  • Page 17: Linux Operating Systems

    3: Troubleshooting Linux Operating Systems For Linux operating systems, all you need to do is install the SpectraSuite software, then unplug and replug in the spectrometer. Technically, the driver files for Linux simply give nonprivileged users permission to use newly connected hardware. There isn’t any long-term harm to plugging in the device before installing the software.

  • Page 19: Appendix A: Calibrating The Wavelength Of The Usb4000

    This appendix describes how to calibrate the wavelength of your spectrometer. Though each spectrometer is calibrated before it leaves Ocean Optics, the wavelength for all spectrometers will drift slightly as a function of time and environmental conditions. Ocean Optics recommends periodically recalibrating the USB4000.

  • Page 20: Calibrating The Spectrometer

    A light source capable of producing spectral lines Note Ocean Optics’ HG-1 Mercury-Argon lamp is ideal for recalibration. If you do not have an HG-1, you need a light source that produces several (at least 4-6) spectral lines in the wavelength region of your spectrometer.

    In this mode, the ExtTrigIn signal acts as an enable switch. If ExtTrigIn is kept HIGH, the USB4000 will acquire spectra as if it was in the normal free running mode. If ExtTrigIn is kept LOW, the USB4000 will not acquire spectra.

  • Page 24: External Hardware Trigger Delay

    HIGH. External Synchronization Trigger In this mode of the USB4000, the integration clock is essentially input into the spectrometer. The synchronized trigger must have a frequency range of 5ms to 60s (shutter mode cannot be used in External Synchronization Trigger mode). If no External Trigger Input Signal is applied, the spectrometer will not take any spectra, and the software will appear “frozen”...
  • Page 25 B: External Triggering External Synchronization Trigger The time between when ExtTrigIn goes HIGH and the beginning of the integration period is specified to be between 8µs<t <10µs. The ExtTrigIn signal does not need to have an even duty cycle, but the time SU_ST between rising edges should remain constant for a given integration time.
