Abstract
Optical assembly containing a) at least two pairs of dichroic beamsplitting elements grouped together such that first sides of these elements are parallel and immediately adjacent to one another and to a predetermined line, and b) two optical lenses disposed such that light transmitted through the lenses towards the beamsplitting element passes through the elements without being scattered at the first sides. Optionally, a first dichroic beamsplitting element in a first pair and a first dichroic element in a second pair have equal optical properties. Imaging probe—for example, a laparoscope—employing such optical assembly.
