The following tables with examples showing what spot sizes and pixel sizes will be
reached in which distance. For individual configuration there are different lenses
available. Wide angle lenses have a radial distortion due to their large opening angle;
the software PIX Connect has an algorithm which corrects this distortion. As an
alternative to the tables below, the optics calculator can also be used on the optris
website (https://www.optris.global/optics-calculator) or via the optris calculator app. The
app can be downloaded for free from the Google Play Store (see QR Code).
