Dielectric coatings as described here have the advantage of being non-absorbing and so allow for greater throughput of energy. These dichroic filters for example, have a dielectric coating that can be used for a 50/50 beam splitter. In contrast, Inconel is limited to 30% transmission and 30% reflection due to the absorption inherent in the metal film.
Standard dielectric beam splitter coatings include 30/70, 50/50, and 70/30. We welcome inquiries regarding any custom requirements you may have.
