Gas Flow Cells UV to Mid IR
Features
Wavelength operation from 150 nm to 3 microns
Designed for minimum optical interference
Compact multiplass for low concentrations/ weak absorption lines
Swagelock fittings for easy integration
The FCM flow cells are optimized for spectrometers and FTIRs, but can be used with tunable laser systems. The cells use large diameter CaF2 lenses for efficient coupling over a 150 nm to 9 micron wavelength range. The housing is a rugged vacuum tight enclosure that can also handle pressures > 400 psi.
Gas Flow Cells for Deep UV to Mid-IR Spectroscopy are multi-mode fiber-coupled ideally suited for customers using their own gas samples and working with fiber-coupled components. Features include:
- Optimized for use with spectrometers or FTIRs and can also be used with tunable laser systems.
- Compatible with fiber with a core diameter of up to 1mm and a NA of 0.37 with a SMA905 connector.
- Wavelength operation from 150nm to 9 microns (UV to mid-IR)
- Designed for minimum optical interference artifacts
- Compact multi-pass design for low concentrations/weak absorption lines.
