Like a rich, stupid person with a lot of free time (I'm none of the above actually)... I purchased an "as is" Leaf Aptus-II 12 (DM 80) from eBay.
I can tell from the pictures that it is missing the IR glass. I know that I need 650nm cutoff, and can buy a custom cut piece online that is close to size, but does anyone know the thickness? I have two apparent options: 1mm or 1.3mm.
I have a Valeo 22wi at home that I can measure later, but I wanted to see if anyone has a DM80 and/or experience in this field.
I will likely buy a 70x70mm or 80x80mm piece, then cut it down to fit on the DB, then make my own frame to screw it/hold it in place. Will the variation in 0.3mm be enough to throw off the focal plane distance?
BTW, the DM80 won't arrive in the mail until mid-February or early-March. But I'd like to have what I need to test it upon arrival.
