Monocromatori
M300
The M300 single monochromator, the first monochromator model introduced by Bentham over thirty-five years ago, remains popular thanks to its compact size and simplicity, ideal for dedicated applications. Compatible with the full range of sources, detectors and accessories of the Bentham portfolio, the M300 monochromator has been deployed in an exceptional range of measurements throughout the UV, visible and IR.
Key features include:
- 300mm focal length single monochromator in Czerny-Turner configuration
- Accommodates single kinematically-mounted diffraction grating
- One entrance slit and one exit slit with multiple configurations available
- Fully automated through USB 2.0 interface
