Description
This is a replacement of the entire sensor stack. This service will replace the stack with a fully functioning CCD11 sensor including our corrosion resistant BG glass. We avoid using CCD5 sensors for the replacement as they are not as stable long term.
Note: At the moment, we do not have support for the Leica M Monochrome for a sensor replacement.
This service fixes the dreaded failed sensor, half screen, or”purple curtain” type failures, that can look like a fully or half dead screen, or like the effect shown below. If your sensor only has spots, you most likely only need our corroded sensor glass replacement services which can be found HERE

Our Repair
That’s where Kolari came in. We’re happy to announce that we can repair the Leica M9 sensor and replace it with corrosion resistant glass starting at $999. We’ve removed Leica coverglass before, but haven’t looked into this repair earlier since there was a warranty option through Leica. We found out about this recent news after a few customers emailed us asking about the repair. So we picked up an M9 with a corroded sensor, and gave it a shot. We were able to delaminate the corroded filter from the sensor, and replace it with BG60 glass. This glass will last indefinitely without oxidizing per Schott test reports, and also allows us to reduce the Leica sensor stack by 0.2mm, further improving on it’s excellent corner sharpness. We can also replace the glass with our full spectrum glass making it IR and UV compatible.
BG61 vs the M9 Original Glass

We are now using a new BG61 glass with anti-reflective coated which is nearly an identical match to the original M9 glass filter. We designed the BG61 to be the same thickness as the original filter while also matching the transmission properties. This is a highly specialized glass made by Schott that is inherently corrosion resistant, even before we put an additional protective anti-reflective and anti-smudge coating to seal from the environment. This filter cannot corrode by design, even if the coatings get scratched.

We also offer a cheaper BG39 glass with a protective anti-reflective and anti-smudge coating to seal it against corrosion. We offer this option with a lifetime waranty against corrosion. We have this available right now at a lower price to the BG61. Color and optical performance is virtually identical to the BG61 glass, however this glass may corrode over time if the coatings get scratched or worn off.
