Hi guys, I am looking for a camera with full size CCD/CMOS sensor but without embedding RGB microfilters. It will be applied for scientific research.
However, I only found this type of camera with tiny sensor in the market. I need high resolution for my research purpose, full size (35mm) is the minimum, prefer high IR sensitive. Large sensor is even better.
You don't say what kind of research you are doing, but for high-quality scientific imaging, there are several companies you can look at: Princeton Instruments, Apogee, Andor, PCO, and some others. Their cameras tend to be designed for low read noise and dark current (often by including thermoelectric coolers), high quantum efficiency and high dynamic range. Most will be monochrome, with color filters sometimes available as an add-on. Most come with F-mount standard, but sometimes there are other options.
Since you want good IR sensitivity, you could look at this from Princeton Instruments (warning: PDF data sheet)
with up to 95% quantum efficiency in the near infrared. (Note that the trick that is typically used to reach these high QEs, backside illumination, can lead to etalon patterns in the near infrared, and the sensors must be specifically engineered to avoid this.) If you want to image at wavelengths above 1 micron or so, you will want to look at InGaAs sensors.
