QHYCCD

Does QHY600M-PH back focus spec includes sensor and camera's glasses?

The QHY600M-PH back focus specification says 17.5mm. Does this take into account of both sensor cover glass and camera's window thickness? If it does not and if both glasses are 3mm thick (total 6mm thick), does that mean the optical back focus is 15.5mm and I would have to add 2mm mechanical back focus to the imaging train?

Please tell me the thickness of Sony IMX-455 cover glass and camera's window.

I hope my question is not confusing.

Thank you,
Peter

Hi,

The BFL value is optical data, so you do not need to add.

Best Regards!

Thank you for telling me this. This will make it easier for me to calculate for mechanical back focus distance of my current camera (QHY600M camera).
