The SR6 is a multipurpose optical spectrometer, valued as a reliable setup for the lab or as a customised system for high-volume industrial and OEM applications. The spectrometer comes in models covering wavelength ranges within ~185-1100 nm, offers entrance slit options in widths from 5 μm to 200 μm, and couples to light sources, optical fibres and sampling optics to optimise configurations for various applications.
The SR6 spectrometers operate with OceanView spectroscopy software and include OceanDirect, a powerful, cross-platform Software Developers Kit with an Application Programming Interface. With its library of functions, OceanDirect allows users to write custom software solutions for their spectrometer, optimize spectrometer performance and access critical data for analysis. OceanDirect also enables High Speed Averaging Mode, a
hardware-accelerated signal averaging tool that markedly enhances spectrometer signal to noise ratio (SNR) per unit time. This promotes higher quality spectra and more accurate results.

The SR6 optical spectrometer has trigger mode options that enable actions such as synchronising spectral acquisition to an external event (e.g., pulsing of a lamp) or timing spectral acquisition to meet certain sampling conditions. Triggering provides accurate timing and synchronisation between the SR6 spectrometer and other devices, adding another layer of versatility to your
spectral measurements.
