Description5pcs/pack DOE 5050 grid DOE Diffraction Gratings for 3D Scanner PMMA 55*0.6mmShape size: 55mm, 88mm, 10*10mm（Custom-made by customers） Tickness: 0.6mm Material: PMMAUse: The grating is widely used in laser projection, such as laser module, laser stage light grating, laser pen, laser level (grating line, cross line), laser cutting machine, laser scanner, laser flashlight, camera focused grating. The pattern can also be designed according to customer design.User instructions: 1. It is forbidden to touch the surface of raster lens with hand. It will lead to blurred graphics. 2. grating lens should pay attention to dust prevention. If there is dust on the grating, it will cause light pricking.
