A prism assembly including two or more prisms, at least one of which has or more surfaces that are used for total internal reflection or partial spectral reflection of incoming light, wherein at least a part of one of the surfaces used for reflection purposes is covered with an element that is spaced apart from the surface, such that a gap is defined in between the surface and the element, and wherein the gap is sealed with a seal that is applied on one of said prisms in order to prevent contaminants from entering the gap.
