Miniature Magneto-Optical TrapMini-MOT
Open, compact glass-cell MOT core · full optical access · built for your own integration
A compact magneto-optical trap core for groups who build their own optics and experiments. The fused-silica glass cell offers fully open optical access for cooling, imaging and control beams; the chamber, alkali metal dispensers (Rb/Cs) and a 5 L/s ion pump are integrated into one unit with a non-magnetic titanium body and a valve-free copper pinch-off seal, so it ships as a sealed UHV module. With a CF35 interface it mounts straight onto your optical table; MOT coils and three-axis compensation coils are optional, or you can fit your own. It complements the fully enclosed 3D-MOT — choose the 3D-MOT to work on arrival, the Mini-MOT for open optics and free integration.
Key Advantages
A sealed cold-atom vacuum core — the optics are yours to design.
Open Optical Access
A fused-silica glass cell with all-round optical access — place cooling, repump, imaging and control beams wherever your experiment needs them.
Compact & Integrated
Chamber, atom source and ion pump in one compact unit with a small footprint that fits existing optical tables and setups.
Valve-Free Pinch-Off
Baked and pumped at the factory, then sealed with a copper pinch-off — no valve, no leak path; the integrated ion pump keeps the UHV going.
Non-Magnetic Titanium
TC4 titanium chamber and flanges — low-magnetic and lightweight, leaving the field at the atoms undisturbed; MOT coils and three-axis compensation coils are available as options for a clean, controllable field.
Built-In Atom Source
Two to three alkali metal dispensers (Rb/Cs) release atomic vapor on demand for a stable, controllable atom supply.
In-House Core Parts
The dispensers and ion pump are made by LinQ, giving dependable supply, service and customization.
