How to protect the beam splitter circuit
KBr-based beam splitters with a germanium-based coating can be used up to 25 μm wavelength, but that material is hygroscopic and must therefore be carefully protected against moisture. It provides an expert-curated supplier directory, buyer-focused technical background information, and structured selection criteria to support professional procurement decisions. Polarizing beam splitters find applications in laser beam control and optical isolators, where separating polarization components is critical. However, depending on the orientation of my wedge beamsplitter, ( but always with the beamsplitter coating facing the part) I either get (sorry for the crappy drawing) a) Sharp image, no change in ghosting b) Ghost image eliminated but image is now blur What gives? Is this common? And how do I make. My light source is beamed onto a 50/50 beam splitter behind which sits my camera but I cannot seems to eliminate ghosting from the surface of the beamsplitter.
