PB8300-050 Multi-pass Sample Cell for Terahertz Spectroscopy
Multi-pass Sample Cell for Terahertz Spectroscopy
The Bakman Technologies’ PB8300-050 multi-pass sample cell is specifically designed to work in the sub-mm and THz regime of the electromagnetic spectrum and integrate with the Bakman line of PB7200 and PB7300 frequency domain THz spectrometers.
With a path-length of up to 5 meters, the cell dramatically increases the detection sensitivity when performing molecular spectroscopy and the athermal design incorporates reflective optics so the instrument remains aligned even with pressure and temperature changes. Further, the coupling optics are integrated into the sample cell so atmospheric gases do not contaminate your measurements.
Features
- - Full adjustable path-length up to 4 meters in an enclosure less than 30 cm long.
- - Designed so that the entrance and exit beams do not pass through the atmosphere.
- - Light weight construction weighing less than 2.5 kg with all of the internal and external components.
- - Designed to be athermal for as little impact to fringe spacing as possible.
- - 'On the fly' adjustable head spacing to allow fine tuning of the fringe pattern.
- - Vacuum sealed enclosure constructed from hard anodized aluminum and carbon fiber.
- - Designed for Bakman Technologies photomixers but may be used with other brands
Applications
- - Microwave and THz Spectroscopy
- - Gas Mixture Analysis and Characterization
