Sensor Replacement Service for the Leica M9 Camera – Kolari
We are now using a new BG61 glass with anti-reflective coating, which is nearly an identical match to the original M9 glass filter. We designed the BG61 to be the same thickness as the
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.
Check our inventory here In August 2020, Leica announced that they will no longer be able to repair the Leica M9 sensor. This sensor had an issue with corrosion or “sensor rot” that was caused by oxidation of the sensor glass. Sensors are typically built with a fused clear glass that covers the BGA grid and sensor microlenses.
This became a particular issue when the M9 sensor glass started corroding across the board. UVIR cut glass is typically made with a Schott BG type material, which is chemically prone to oxidation. We saw this over a decade ago with our first hot mirror filters which are built with this same type of glass.
Leica made a range of sensors throughout the lifespan of the M9's production line. CCD 11+ sensors came at a later point and did not suffer from the acid gel formation issue present in earlier models. CCD 11+ sensors have a much harder original adhesive bonding the glass to the sensor and are more time consuming to replace with Schott Glass.
