The EPP2000C UV-VIS spectrometers utilize a 40 mm diameter concave grating with aberration correction to provide superb imaging. This significantly improves spectral shapes by eliminating comma and stigmatism found in plane grating spectrograph designs. The flat field spectrograph architecture does not utilize mirrors, and therefore provides the lowest possible stray light in the UV with additional assistance from the holographic line grating. A multi-band filter is integrated into the spectrograph to provide order sorting and prevent optical aliasing. The optical signal is input via single strand fiber optic cable into a standard SMA-905 connector. Standard Models | EPP2000 Model | Wavelength Range (nm) | Grating
