      D21 AR window fits the new ASI462MC camera. We don’t recommend you replace it by yourself.

    Hi, on my ASI 224MC, my protective glass was scratched.
    This protective window is mandatory to have a good focus or it’s not necesary to have one ?
    Should i order a new one ? AR or UV/IR cut ?
    Thanks

      It is used to protect sensor. AR or UV/IR cut depends on your photograph need, both were OK.

    As a follow up to my earlier post/question. I have added a IR/UV cut window to my ASI183MC. I purchased a 31mm Optolong filter. It’s the same thickness as the AR window and seats nicely on the existing O-Ring. I added a 0.5mm filler around the edge to keep the filter centered…. works great!! I just wanted to pass this along incase anyone else has a similar need.

    Do you have plans to introduce a 32mm IR protective window? I have the ASI183MC and really need this in place of the standard AR window. If not, do you know any manufacturer who may offer this please?

    Hallo, ich habe die ASI178MM und habe eine Frage zum AR Schutzfenster. Mein UV- Venusfilter hat ein IR-Leck und erzeugt schwache Geisterbilder . Ich habe das AR Schutzglas von der Kamera entfernt möchte wissen ob es besser ist das Glas wieder vor den Sensor zu setzen oder stattdessen einen reinen IR-cut Filter zu kaufen.

    Where can I find instructions on how to remove the protective window? I read the instructions on how to clean the sensor and window but it does not mention there how to remove the window itself. I haven’t received my camera yet so it could be a simple step but in case it is not can someone point me in the right direction?

    Does it matter which way around the glass is placed over the sensor? I took mine out of my 120MM for cleaning and lost track of which side faced the sensor.
