A Youtube video below shows the CFA removal process from Canon 350D DSLR sensor to turn it into a monochrome imager for astronomy:
And this video shows the process almost complete:
A picture showing the monochrome resolution improvement is posted on Fickr.
Looking at this photo - I can't help but feel some pain for this imager and the effect that this scraping will have on it's quality.
ReplyDeleteMy suspicion is that the monochrome imager will now see a very "starry" night of defects when capturing images of the night sky.
Actually, you can see these monochrome images on the Flickr link on the last line in the post. Not that many defects there. This has amazed me too.
DeleteWhat is austronomy? astronomy under an austerity budget?
ReplyDeleteThanks, I've fixed the typo.
DeleteThis falls into the same category as using your Canon EOS 1D as a hammer. You could do that, but probably wouldn't want to...
ReplyDeleteThat looks crazy. Surely a solvent soaked Q-Tip would be a "safer" method to remove the organic layers. I guess it shows how strong the thin CVD silicon oxide and nitride layers are in modern ic's
ReplyDeleteUh I didn't know image sensors are actually

Great way to sell cameras. Scratch and see if you're a lucky customer! I have heard of removing the IR filter from a cheapo camera to get a relatively cheap (and probably not very good) night vision device. Anyone try this?
ReplyDeleteWhat type of solvent would you use to do this chemically, hopefully a little more safely?
ReplyDeleteSulphuric acid/peroxide mix, acetone, or carbitol (assuming you don't have an oxygen plasma available).
ReplyDeletedichlorethane has been called in the list of solvents, at least for nikon Sensors.
ReplyDeleteOr, you could either A) buy a monochrome camera or B) buy any Sigma camera with a Foveon sensor and remove the IR cut filter behind the lens (then put it back to take color pictures again).
ReplyDeleteHi, Great work!
ReplyDeleteHow did you remove the cover glass on the sensor?
