Longpass Dichroic Mirrors, 2-inch Round — Model DM20-650LP

Ø50.8 mm, substrate UV Fused Silica.

Product Description

  • Substrate Material: UV Fused Silica
  • Four sizes available: Ø12.7 mm, Ø25.4 mm, Ø50.8 mm, and 36.0 mm × 25.0 mm
  • Application: Filtering and beam splitting

LBTEK Dichroic Mirrors can separate light beams based on wavelength. Longpass Dichroic Mirrors transmit light above the cut-on wavelength while reflecting light below it, featuring high transmission and high reflection characteristics. Our dichroic mirrors are available in 13 cut-off wavelength options: 425 nm, 490 nm, 505 nm, 550 nm, 605 nm, 638 nm, 650 nm, 805 nm, 950 nm, 1000 nm, 1180 nm, 1500 nm, and 1800 nm, with average transmission and reflection rates exceeding 90% within the specified wavelength ranges. LBTEK offers four size options: Ø12.7 mm, Ø25.4 mm, Ø50.8 mm, and 36.0 mm×25.0 mm. Our dichroic mirrorsrs have a filter coating on one surface and an AR coating on the other. The arrow points to the filter-coated surface, and incident light is directed from this side. LBTEK also offers shortpass dichroic mirrors, which transmit light below the cut-off wavelength while reflecting light above it. In addition to standard dichroic mirrors, LBTEK also offers a variety of custom dichroic mirrors. Please contact LBTEK Technical Support for special requirements.

Longpass Dichroic Mirrors, 2-inch Round

  • Substrate Material: UVFS
  • Size: Ø50.8 mm
  • Application: Filtering and beam splitting

LBTEK dichroic mirrors can separate light beams based on wavelength. Longpass dichroic mirrors transmit light beams above the cut-on wavelength while reflecting those below the cut-on wavelength, featuring high transmission and high reflection characteristics. Our dichroic mirrors offer various cut-off wavelength options, achieving average transmission and reflection rates of over 90% within specified wavelength ranges. One surface of the dichroic mirror is coated with a filter coating, while the other side has an anti-reflection coating, with the arrow indicating the surface coated with the filter coating.
