McPherson’s (Chelmsford, MA) grazing incidence wavelength dispersive optical spectrometer allows rapid analysis of spectral light in the ~1 to 300 nm wavelength region (4 to 1200 eV). Beside high-harmonic laser generation experiments, the Model 248/310 is also useful for measuring ion- or discharge light sources and astrophysics detector calibration. The Model 248/310 ships completely assembled and tested for spectral-resolution and with vacuum leak test certification.

Adapters, differential pumping, and grazing incidence collection optics to more easily connect to the experiment can be included. Every shipment is complete with a wavelength calibration certification. McPherson grazing incidence optical spectrometers use angles between 84 and 88.5 degrees for preferentially good XUV throughput to energies around 1200eV (~1 nm). High vacuum ready, the McPherson Model 248/310 spectrometer can also be prepared for ultra-high vacuum (UHV).
