COTS Beamsplitters are used to split a laser beam into separate beams in defense or security applications. COTS Beamsplitters use a variety of substrates, coatings, or a combination of the two to reflect a portion of the laser beam while transmitting the rest. COTS Beamsplitters are low cost alternatives to expensive custom components. A wide range of beamsplitters are available to meet the needs of many applications.
