The system combines the Jobin Yvon expertise in the following areas: Spectroscopy system development Vacuum design Toroidal Aberration Corrected Gratings The VTM offers unique performance in the UV and VUV wavelength range. Equipped with an aberration corrected holographic toroidal grating (1200 g/mm) the VTM 300 allows monochromator or spectrograph operation with the same grating. Thanks to this toroidal grating the VTM 300 presents a unique throughput at 100 nm and below. Unique Features in UV and VUV Wavelength Range Toroidal Aberration Corrected Grating High Throughput Interchangeable Kinematic Grating Mounts Focal Length 300 mm Deviation 70 deg Spectral Wavelength Range 60-300 nm Spectral Resolution <4 Angstrom High Repeatability Monochromator and/or Spectrograph Bi-dimensional Detection Adapter 25 mm Flat Field Removable Entrance and Exit Slit High Vacuum Compatible (10-6 mbar) Adjustable or Fixed Entrance and Exit Slits Aperture: f/7.5 Stepping Motor Drive Spectral Performance Click on thumbnail to see full size image Repeatability test with 253.6 nm Hg line Helium Full Range Scan Helium Line 58.4 nm Hydrogen Line 121.6 nm Mercury Line 194.2 nm Mercury Line 253.6 nm
