Assisted 2x2 Fiber-optic & Electric Rotary Joint - 24 contacts
Assisted 2x2 Fiber-optic & Electric Rotary Joint - 24 contacts
Voici une description courte popur vouir ce que ca donne seulement... Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor
The 2x2 Assisted Fiber-optic & Electric Rotary Joint allows friction-less rotation of 2 independent optical channels and 24 electrical contacts thanks to motorized assistance. The rotary joint detects torsion in fiber-optic patch cords connecting it to a moving animal, turning the rotor and allowing the animal to move freely without discomfort.
The two optical inputs use a standard FC connector, while the optical output uses two M3 receptacle. Each optical channel is independent and features near zero crosstalk. The 24 electrical contacts are accessible using either a combo of an HDMI connector plus 4 auxiliary contacts or dual Omnetics PZN-12 connectors.
This configuration uses achromatic doublet lenses to ensure consistent performance on the entire visible range from 450 to 650 nm, fiber-optic numerical aperture is limited to NA 0.22. This rotary joint is optimal for use in optogenetics, allowing two regions of the brain to be activated independently.
