Baader Adapter C-Mount to T2 internal thread with built-in IR
Blocking filter – allows the adaptation of C-mount cameras to lenses
and telescopes via the T2 thread.
Lens systems or correctors are for the IR light (very
long-wave red light) not sufficiently corrected. The chip the
The camera, on the other hand, absorbs this light. The result is one
Deterioration of the contrast. The IR blocking filter blocks this
light off, preventing the contrast from deteriorating.
There is also a mounting thread for 1.25″ filters (M28.5 x
0,75). A 360° rotation of the T2
Thread approach allows.
Camera-side thread: C-Mount (25.4mm) external thread
Thread on lens side: T2 internal thread (M42x0.75)
