Amazingly bright holographic diffraction grating!
Our replica diffraction grating is the most efficient grating ever offered. This specially developed, high-efficiency diffraction grating is more efficient than acetate gratings. Use these gratings to demonstrate emission spectra from spectrum tubes. Previously dim lines are now visible! Produce multiple beams from a single laser for great optics demonstrations or experiments. Bright rainbows can be formed to fuel a classroom discussion of diffraction. These gratings have 750 lines per millimeter and are enclosed in durable 35mm glass slide mounts. This product comes with a data sheet that provides an explanation of holographic diffraction, activities and tips on the care and handling of the product.
