After my post over a week ago, several other companies popped up online that provide repair services for corroded Leica M9 CCD sensors. In addition to Kolari Vision, there is also Maxmax and at least one more company that I will mention online later once I get permission to do so. Here are the details on the conversion options provided by Maxmax (including an option to convert to Monochrom):
1: Replace the defective ICF with a new ICF leaving the camera as a color camera: $1,500
2: Replace the defective ICF with a UV-VIS-IR window making the camera into a full spectrum color camera: $1,500.
Note that with this conversion, you will generally want to use a filter on your lens. For visible light pictures, you would use our UV and IR blocking XNiteCC1 filter. If you wanted to take an IR picture, you could use a variety of IR longpass and bandpass filters. If you wanted to take a UV picture, you would use a UV shortpass filter. We have hundreds of filter options in diameters from 25mm to 82mm.
3: Replace the defective ICF with a new ICF and change the sensor to monochrome: $2,500
4: Replace the defective ICF with a UV-VIS-IR windows making the camera into a full spectrum monochrome camera : $2,500.
UV sensitivity will be about 6x greater than leaving the camera as a color camera. Again, you would generally be using filters on your lens depending on what type of light you want the camera to see.
Kolari Vision is now repairing corroded Leica M9 CCD sensors for $1,000
