Transmission grating beamsplitters are commonly used for He-Ne laser beam division and multiple laser line separation in visible wavelengths. The transmitted beam is diffracted into multiple orders. Transmission grating beamsplitters consist of a refractive index matched epoxy replica on a polished glass substrate in order to get a high total diffraction efficiency. These beamsplitters are specially designed for He-Ne laser.
