## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Inverse of prism
*by R***D on September 27, 2019*

Not what I expected, but fun, useful, and fair quality. Prisms refract the light into a room environment, these diffract that light coming in, so that they need to be near (your eye or a camera lens) to see the diffraction effect. Recommend using for camera filter effect vs. not held to your eyes, because the spectral output is different pure frequencies that could damage your eyes (probably not, by why chance it?).Fun and great quality for a slide style, but there is some dust as another reviewer mentioned. Dust is Not hard to removed with a camera lens brush.

### ⭐⭐⭐⭐⭐ The 1000 lines is better than the 500 lines
*by J***Y on December 1, 2012*

I compared the 1000 lines with 500 lines, and have to say that the 1000 lines is definitely able to show more details in spectra. These are great for introductory spectroscopy discussions in Astronomy classes; what I use them for. What a student can expect to see after some explanation of what to look for, is a series of spectral rainbows with absorption or emission lines. The lines do change positions based upon elements and energy levels. Yes, that sounds very elementary. But, for a student with no experience, this can be eye-opening and exciting. I found these gratings to be a great introduction to spectroscopy; and, a good lead into using higher-end spectroscopes.

### ⭐⭐⭐⭐⭐ Worked well for HS Physics lab with lasers
*by T***C on August 19, 2020*

I used in a HS physics lab with a red and green laser to determine wavelength. Lab was easy to do and we got good results with these slides.
