The United Scientific DFG600 diffraction grating has 600 lines per millimeter, measures 45mm x 60mm (H x W), and is protected by glass plates. This replacement diffraction grating with 600 lines per millimeter splits light into multiple beams for analysis in light and optics experiments. The grating measures 45mm x 60mm (H x W) and has a viewing area of 30mm x 45mm (H x W). Dual glass plates protect the grating from damage and provide visibility. It is for use with the United Scientific SPECT01 spectrometer.
United Scientific Supplies manufactures laboratory supplies and science education products. The company, founded in 1992, is headquartered in Waukegan, IL.

It's a little flimsy and the glass faces are too reflective. It was cheaper than some others and more expensive than the cheap ones, which are seriously flawed and useless for amateur spectroscopy.

Aside from the fact that the grating that I received was not the one shown on the ad page, it was very poorly made. Also, as described by another reviewer, the grating was received covered with fingerprints. Moreover, I tested the grating in a spectrometer and there is no way to get sharp spectral lines. The best you can get are badly smeared lines. From prior experience with gratings that look like the photo in the ad, those gratings seem satisfactory. But that is not what I received. Imagine a 35mm slide all in black except for the small picture (grating in this case) area. That's what I got.

Poorly made... Had lots of scratches, fingerprints, some paper label glued to it... Not a quality optical component, but works ok as a diffraction grating to play with.Plus the actual product looked different from what is pictured.

Works well for experiments with light sources, including the sun (careful with sun light!)
