Replace IR Glass for Aptus-II

[steven_jacobs_englund]

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.

HI

We would recommend Schott S8612 which has a cut off at 650nm just like you say.
1.0mm would be what we would use on a 80mp sensor.
Keep in mind that different sensors use different filters so your 22mp sensor is most likely using a different filter.

Thanks Ulf. That's great to hear I am headed in the right direction. I went with the 1mm glass.

Fingers crossed the back arrives and actually works, otherwise this is all in vein.

@Ulf - My digital back arrived today but it's missing the CF reader board and firewire board. Is there any way I can purchase parts or service for the DM80?

[Ulf]

Hi
Are you saying the boards are missing inside the back?
If so, return it whom ever you have purchased it from as it is a incomplete unit.

The parts are not available for purchase and even if they where, they would not do you any good without production computer with specific software and configuration.

@Ulf: Hi
I have the same problem as @steven_jacobs_englund. I bought an Aptus-II 10 and an Aptus-II 12 from ebay without CF reader board. I'm experimenter so I tried to combine the CF reader board from my old Aptus 65 (part no.: 503-00309H-A). Surprisingly it works (with some limitations). Could you please tell me how can I purchase a CF reader board for Aptus-II?
Or perhaps you sell the products sent back to you for maintenance, or repair, but have another defect. If so, I would be happy to buy one or two with working CF reader board for parts(or any solution)
Thank you,

Hi

Parts are only handled by authorised service engineers.
We do not sell internal boards outside of this and we do not recommend anyone whom are not a factory trained service engineer to open and modify camera back.
