BSNN1-25.4S-X / BSNB1-25.4S-Y
Plate · 50/50 ±5%
Beamsplitter Plate — 25.4 mm, 50/50
A 25.4 mm square BK7 grade-A beamsplitter plate for splitting or recombining beams, especially in high-power laser work where low absorption matters. T/R = 50/50 ±5% for random polarization at 45° incidence. Narrow-band (X) versions are available at 488, 514, 633, 780, 850, 1064, 1300 and 1550 nm; broad-band (Y) versions cover 450–680, 650–850, 900–1200 and 1200–1550 nm. Flatness λ/4 per 25 mm, parallelism 1 arc minute.
