Orthogonality of CCD with the focal plane

[Subaru]

Dear Atik,

Can you advise if the Atik series 4 cameras are fabricated with a tight tolerance on orthogonality with the focal plane?

The current astrographs are very sensitive with the tilt of the focal plane, and I would like to know if the Atik cameras are built with this in mind.


Regards,

David

Hi David,

Yes, we adjust the mechanical tilt of the CCD down to max of 10um tolerance.
