Home / What is a grating beam splitter
A grating beamsplitter is an optical device that utilizes the principles of diffraction to split a beam of light into multiple beams, often redirecting them at specific angles. Beamsplitters are often classified according to their construction: cube or plate. Gratings are arrays of apertures characterized by the period, the duty cycle (metal width/period), the material height, and the layout area. We can supply gratings with layout sizes ranging from 60 x 20 mm² to 160 x 90 mm². Coligh specializes in the production of diffractive beam-splitting elements, and we have produced a wide range of 2D Diffractive Beam Splitting Gratings, with the highest array of dots that can reach 33X33 over any area, and with optimal diffraction efficiency of 80%-90%.
