The latest models 180i/320i are imaging spectrometers with a high-throughput Czerny-Turner configuration. Astigmatism correction allows multi-track real-time measurements with a CCD camera, and the USB interface allows easy Plug & Play control from your computer. A wide variety of accessories such as light sources, input/output optics, and detectors can be used for a wide range of applications.
