Abstract
An adjustable aperture device for an electromagnetic radiation detecting apparatus includes a position adjustment body configured for adjusting a position of a selected aperture hole of multiple selectable aperture holes, where electromagnetic radiation propagates through the selected aperture hole. The adjustable aperture device further includes a guide unit configured for guiding the position adjustment body along a predefined guide direction, and an aperture body defining the aperture holes and including multiple engagement sections, where the adjustment body is engagable in a selectable one of the engagement sections to thereby select the selected aperture hole. The adjustable aperture device further includes a pre-loading element configured for pre-loading the position adjustment body towards the aperture body, and a drive unit configured for driving the aperture body to move so that the position adjustment body is engaged in a respective one of the plurality of engagement sections.
