Beam combiner minangka pangilon semi-transmissive sing nggabungake rong (utawa luwih) dawa gelombang cahya dadi jalur optik siji liwat transmisi lan refleksi.Beam combiner biasane ngirimake cahya infra merah lan nuduhake cahya sing katon (beam combiner digunakake nalika inframerah CO2 laser daya dhuwur nggunakake helium-neon laser diode katon kanggo straighten dalan cahya).
1. Short-wave pass beam combiner (45 derajat): T>97%@960-980nm/R>97%@1020-1040nm
2. Long-pass beam combiner (45 derajat): R>95%@1041nm/T>95%@1065nm
nglereni laser, welding laser, cladding laser lan perawatan medis laser lan lapangan liyane.
