Beamsplitters

We provide cube, plate or special prism beam splitter that various materials and AR coating are applied based on right angle prism production technology.

Standard Cube Beamsplitters

Standard beamsplitter that divides the incident light by the designated ratewithout considering wavelength or polarized light is quite suitable for lighting products or one-way mirror.

Non-Polarizing Cube Beamsplitters

Broadband Non-Polarizing Cube beamsplitters reduces the effect caused by incidence angle change of converging/diverging beams as it shows the even spectrum over the whole designated wavelength range.

Plate Beamsplitters

Plate Beamsplitters is capable of low cost design, using various sizes and various Beamsplitting ratio. Our Plate Beamsplitters can be composed according to various usages. Whole efficiency of beamsplitter can be improved through the second surface that AR coating is applied in many products and prevent the unwanted ghost reflection. In case tailor-made size or different reflectivity/transmissivity, please call our sales division.
