EISCO Economy Spectroscope Tube - 500 Lines/mm Grating - Eisco Labs

easy to use quality for price

I am puzzled by some other reviews. This spectroscope is an inexpensive teaching tool that is better than many of the oline tutorials that show home-made versions. Sure, making your own is fun, but for ten bucks, I choose to use this to teach my student about light spectra from various light sources.Naturally, this is scope is not able to provide quantifyable measurements. But, I'd speculate that it might work (with modification) with the open source Thermino software.

made of cheap plastic and cardboard - performs OK

We purchased this for a homeschool science unit and my daughter said “this is the coolest thing that’s happened all month!” Then carried the lens everywhere with her for days!Definitely worth it, especially if you don’t feel like gathering all the parts lessons call for to make one!

more like a toy than a serious instrument. but this is good enough to get a General Idea of what the light spectrum looks like from different light sources.if I didn't already know what I was looking at I think it would be difficult to learn from this. for homeschooling or classroom use it would be better to get one with a scale. even if the scale was somewhat inaccurate it would at least give you a ballpark indication. with this one it is entirely up to your knowledge of what to expect in order to interpret what you are seeing.I wanted to compare some LED lighting to some florescent and incandescent lighting. it was good enough for that but only just barely.

This is junk, just like Eisco's triangular-shaped spectroscope. One can't view spectral lines with it. I used a similar one as a kid which also used a slit with diffraction grating and one was able to see both absorption and emission spectra with it. Can't see them with this one. Waste of money by the buyer. Eisco makes better products, but their low-end spectroscopes shouldn't be on the market.

I don't see any difference when pointing it at the light sources around me and don't want to risk looking at the Sun with it.My thought when purchasing it was that I would hold it up to the eyepiece of my telescope to compare the spectrums of various classes of stars but it doesn't seem like that will work. A star is a tiny point of light, even in an amateur telescope and it will be difficult to keep the small slit at the end of the long tube centered over a constantly moving star.The construction is very cheap. It is a long narrow plasterboard tube with a plastic end cap on one end that has a narrow slit in it. On the eye end is another plastic cap with a window contain a small piece of diffraction grating.In use you look through the diffraction grating end of the tube while aiming the slit end at a light bulb or other light source. It looks like the bigger or closer the light source the easier it will be to use.Being pasteboard it came home from the first outing with a dog leg kink in it. I am wondering if a can mount the end caps on a length of Schedule 40 to salvage it.This is my first experience with a spectrometer but I didn't notice any Fraunhofer lines.⭐⭐⭐Is my base rating for a product that is fully functional and delivers on its promises

This thing is very cool could be used as a tool for educaters! I'm 21 and bought it just for fun.
