WebWe recommend a sensor size of at least 3 times the largest diameter. For the pixel pitch (or, equivalently, pixel size), we recommend that the smallest beam you will measure should fit within at least 10 pixels. For example, if the sensor has a pixel pitch of 5.5 µm, you should not try to measure beams smaller than 55 µm with it.
