 Transmission Grating Beamsplitters

Transmission Grating Beamsplitters

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.

Precautions:
Optical gratings can be easily damaged by moisture, fingerprints, aerosols, or the slightest contact with any abrasive material. Gratings should only be handled when necessary and always held by the sides. Latex gloves or a similar protective covering should be worn to prevent oil from fingers from reaching the grating surface. No attempt should be made to clean a grating other than blowing off dust with clean, dry air or nitrogen. Solvents will likely damage the grating's surface.
