Vacuum UV Spectroscopy
VTM 300 - Vacuum Toroidal Monograph 300
The HORIBA Jobin Yvon VTM 300 system gives you a unique opportunity to enhance your spectroscopic capability to the Vacuum Ultra Violet region. The system combines the HORIBA 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.
