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 selectively separate beams based on wavelength, achieving high-efficiency transmission and reflection in specific wavelength ranges. Long-pass dichroic mirrors transmit beams above the cut-on wavelength while reflecting beams below the cut-on wavelength. Within the specified wavelength range, the average transmittance and average reflectance can both reach above 90%. In terms of structural design, one surface of the Dichroic Mirror is coated with a filter film, and the other surface is coated with an Antireflection Coating (AR Coating). The edge of the mirror is marked with an arrow indicating the surface coated with the filter film. It is recommended that the beam be incident from this surface for optimal optical performance. Standard products are available in four specifications: Ø12.7 mm, Ø25.4 mm, Ø50.8 mm, and 36.0 mm × 25.0 mm. Additionally, LBTEK offers custom solution for Dichroic Mirrors to meet the special requirements of different application scenarios. For more information, please contact LBTEK technical support.

Fluorescence Dichroic Mirror
  • Substrate: UVFS
  • Dimensions: 36.0 mm x 25.0 mm x 1.0 mm
  • Incident Angle: 45°±1.5°

LBTEK Fluorescence Dichroic Mirrors adopt a high-performance UV Fused Silica (UVFS) substrate, specifically designed for 45° oblique incidence optical paths. They feature high reflection in the short-wave range and high transmission in the long-wave range, enabling precise separation of optical path signals. The purified excitation light is reflected to excite the sample, while specific fluorescence signals are efficiently transmitted, ensuring a highly efficient and lossless optical path. The products have accurate spectral calibration, no crosstalk, and no stray reflections. Each model can be precisely matched with corresponding filter sets. Fluorescence Dichroic Mirrors come in a standard size of 36.0 mm x 25.0 mm x 1.0 mm, compatible with mainstream filter cubes, coaxial optical paths, and microscope modules. Both surfaces of the dichroic mirror are coated with a filter coating and an antireflection coating. The arrow (<) on the side points to the filter-coated surface. During use, light should enter from the filter-coated surface.

LBTEK fluorescence dichroic mirror is often installed in a 30 mm coaxial cube rectangular flat mount
