A plate beamsplitter is an optical window with a semi-transparent mirrored coating to break a beam into two or more separate beams. The reflectivity and transmission can vary by ±5%. Experimental Grade Plate Beamsplitters are offered in a variety of reflection/transmission ratios for a range of experimenting or prototyping applications.
Note: Specifications for experimental grade optics may vary as much as 10% from those listed. Also, no additional information is available other than what is provided.
