Pinhole shutter for laser scanning microscopy has a simple cost-effective cam arrangement that provides accurate adjustment of size and position of the pinhole

摘要

Pinhole shutter for laser scanning microscopy has a shutter hole (14) with a defined size and position within the shutter plane and an adjustment mechanism for adjusting its size and position. The adjustment mechanism has at least two cams (2-5), the rotational position of which defines the size and position of the hole.
