The curvature (convex, concave) and the unevenness of the beam splitter primarily have a negative effect on the reflected wavefront. The beam reflected by 180° gets a deviation twice as large as the distance of the surface error (flatness) of the beam splitter due to the double. Advantages of a plate beamsplitter include less chromatic aberration, less absorption due to less glass, and smaller and lighter design compared to a cube beamsplitter. Disadvantages of the plate beamsplitter are the ghost images produced by having light reflect off both surfaces of the glass. There are a variety of beam splitters for these applications, with different advantages and disadvantages. Customized dichroic mirrors that are suitable for. Microscopes and optical setups in general consist of various optical components, and the performance of the system (resolution, contrast, etc. (2) Compared with the fused taper splitter, the cost is higher, especially. Cube beamsplitters also require more space to mount, which can be a disadvantage in space-constrained setups. See the BS Cube Mounting tab for our cube mounting options.
