## Questions & Answers

**Q: What is the grating length, height and blaze angle?**
A: The cut out window measures 1 x 1 - 3/8 inch (25x35 mm).   Best viewing angle seems to be around 30 deg, if that corresponds to blaze.

**Q: With a good mirror at the back, can it function as reflective grating?**
A: No it will not. It would work as if the light went through the grating twice.

**Q: Does this work like a spectrometer? I need to be able to detect if specific wavelengths are present in a room's lighting.**
A: If you project the dispersed light onto a screen, you might be able to roughly see what wavelengths exist and their relative intensities.  For finer measurement, you might need an array of photodetectors or a camera.  Or you can look at the incident light directly from different angles and have a way to measure those anles, kind of like those antique spectroscopes, though you should be careful not to stare at overly intense light or UV sources.

**Q: is the diffraction grating on flexible film or rigid plastic, or glass?  Is it etched or produced photographically?**
A: It's cardboard on the outside and plastic where it counts in the middle.  I assume it can't be etched on plastic, but I'm not certain.  In any case the price reflects that there is no glass in this product.  I would also suggest plastic is safer than glass for kids, although given the small size the chance of someone getting hurt on a glass version of this product would seem unlikely.
