Technical Data
The dichroic mirror can separate a light beam according to a wavelength, and the short-wave pass dichroic mirror can transmit a light beam lower than a cut-off wavelength while reflecting a light beam higher than the cut-off wavelength, and has high transmission and high reflection characteristics. Our dichroic mirror has 14 kinds of cut-off wavelength: 425 nm, 490 nm, 505 nm, 550 nm, 605 nm, 638 nm, 650 nm, 780 nm, 805 nm, 950 nm, 1000 nm, 1180 nm, 1500 nm and 1800 nm, their average transmittance and average reflectance in the specified band range can reach more than 90%. LBTEK is available in Ø12.7mm, Ø25.4mm, Ø50.8mm and 36.0mm × 25.0mm sizes. One surface of the dichroic mirror is coated with a filter film, the other side is coated with an antireflection film, and the arrow points to the surface of the coated filter film. LBTEK also provides a long-wave pass dichroic mirror that can transmit light beams above the cutoff wavelength while reflecting light beams below the cutoff wavelength.
