Optical beam splitter TS-07 series

dielectriccubicpartial reflectance

Overview
The TS series cube beamsplitter transmits and reflects incident polychromatic light at θ = 45° with an approximately 50:50 split across the visible range (400–700 nm). Four outer polished surfaces are provided with antireflection coating. Custom sizes and non-standard wavelength ranges can be manufactured on request.
