The 1x2 Fiber-optic Rotary Joints are used to divide the light coming from a single input optical fiber on a fixed side to two output optical fibers on a rotating side. The 1x2 Fiber-optic Rotary Joints - Intensity division sends half of the input light into each of the two output receptacles. This is particularly useful for bilateral stimulation experiments, where the illumination intensities must be the same in each channel.
• A compatible holder is included with the 1x2 Fiber-optic Rotary Joints (Holder_FRJ_large).
• The output fiber-optic patch cords are included.
• An optional gimbal holder can be used to simultaneously pivot and rotate the rotary joint around an axis (GH_FRJ).
|Maximum variation||+/- 3% of the mean|
|Transmission||Over 40% per channel|
|Output NA||0.22 or 0.5|
|Start up torque||30 µN·m|
|Outer Diameter||31 mm|
|Note||Tested with 200 µm core NA 0.22 fiber-optic patch cords|
A gimbal holder allows pivoting the rotary joint along two additional axes, further reducing the mechanical stress on the animal.
