The Ocean Insight (Ocean Optics) USB series spectrometers are legacy systems that are offered as backups to existing systems in field. For general purpose UV-VIS-NIR spectrometers we recommend the Flame series based on cost and performance along with having interchangeable slits. For the USB series we recommend you use Oceanview 1.6.7 for better compatibility.
Contact us (via email here, or 651-407-9582) if you need a custom configuration to match (backup) your existing system. You can send us a screen shot in Spectrasuite or Oceanview of the system configuration.
