Pixel size tells you how large an area the pixel has for collecting photons. For example, a 6.5×6.5 μm pixel has an area of 42.25 μm2 and an 11×11 μm pixel has an area of 121 μm2, making the 11×11 μm pixel ~2.86x larger than the 6.5×6.5 μm pixel. So, if the 11×11 μm pixel collects 100 photons, the 6.5×6.5 μm pixel only collects ~35 photons. This means that, as far as sensitivity is concerned, a high QE and a large pixel are preferred. However, larger pixels can be disadvantageous for resolution.

I agree with you completely – unfortunately, it’s a stopgap solution.

I thought your feedback was very good, I was just suggesting it be done in a way that seems less aggressive. I also thought it was worthy of an answer, but I can understand making it a comment. I do not disagree on the IR algorithm, on top of that, nicer cameras have algorithms implemented internally to filter IR because it is cheaper than a filter. I would suggest having a bright IR light to test for the filter. Silence your cellphone and place it in a position that allows the proctor to see your computer monitor, your workspace, and yourself .
Typically, pixels will be cleared before an acquisition but dark current will still build up until the pixels are cleared again. To solve this issue, the dark current is drastically reduced by cooling the camera. You can calculate how quickly dark current builds up on your camera with the method below. Read noise is present in all cameras and will negatively contribute to the signal to noise ratio.
