Exactly what we ordered
I had no idea what this was but my physics minded son wanted it for Christmas. I was a bit worried when it shipped from overseas and when it got to the US, all I had for tracking was "picked up by another carrier" but sure enough, it arrived shortly after. Packaged extremely well and a nice little case for it. So my son opened this present this morning and it's been the highlight of the day. It works perfectly and is a really cool tool, even for those of us that don't understand it.

Best price and great product!
I got to see how one of these pocket diffraction grating spectroscopes would perform and seems great IMO for the price. Next to fabricate an adapter and make into a webcam and other camera like camera phone option with Theremino or the one like Les' Lab app.

It does the job
It's a bit small and doesn't have a scale, but it does what it' supposed to do. Image shows spectra from a fluorescent lamp above my bed. I brought the spectroscope close to the camera lens of a tablet to take this picture. Emission bands at 436, 487 and 546 nm. due to mercury and terbium were identified with the help of wikipedia. When you turn on a fluoresent lamp, rushing electrons crash against the external electrons of mercury gas, making them jump to higher energy levels. When they fall back down, they emit photons, mostly ultraviolet, which are absorbed by rare-earth elements like terbium coating the inner surface. They in turn are excited and emit visible photons

Don't waste your money.
I'm mad I went for the cheap one. Live and learn.

Very compact, easy to see
The eye relief on this is very tight (you have to have your eye VERY close to be able to see the spectrum), but I love that it appears in the MIDDLE of the field of view. With cheaper, low-quality versions of similar spectroscopes, your spectrum appears off to the side a bit, but in this one it is dead center. I will be using this to make a digital spectroscope project using a Raspberry Pi, and it lines up with the Pi camera very well since the spectrum here is dead center.

Borderline usable
This thing is tiny, like the size of a pinky finger.The focus distance is weird and not adjustable. I have to wear my glasses when using this to be able to make out details.You need a LOT of light coming through the gemstone to be able to see its spectrum, and you need a light with a full spectrum, like from an old-fashioned bulb.The image is very small and you have to move around the eyepiece to get the perfect angle to see anything at all. There's no scale, but you wouldn't be able to read it even if there was one. You can tell generally where spectral lines are present, but not with any precision.As a hobby tool it's kind of expensive. I would not use this for any kind of commercial use.

Works well for my purposes
I mainly want to see the spectrum of various light sources, and this is very portable and works well

Nice little spectroscope
Bought it so i could attach a camera to it for recording spectra.Still in the process of doing that.It should work well for that purpose

Useful
A simple tool to check the spectrum of gems. Not the clearest visual representation of absorption bands but a good indicator.

Muy aceptable por el precio que tiene
Tiene una resolución aceptable para las dimensiones que tiene. La relación rendija-foco que determina la resolución para una densidad de lineas fija es suficiente para resolver algunos dobletes en lámparas de Hg-Ne. Se pueden ver con bastante claridad las líneas de absorción al apuntar al cielo nublado y puede utilizarse el segundo orden para resolver detalles en la región violeta. Recordemos que se trata de un espectroscopio y no de un espectrómetro, por lo que evidentemente carece de escala graduada.En las imágenes, una lámpara fluorescente convencional y un láser NdYAG doblado (532 nm).

Tolles Preis Leistungsverhältnis, gute Auflösung Fraunhofer Linien erkennbar
Kaum zu glauben, wie scharf das kleine Teil abbildet. Ja es stimmt, mit bloßen Auge habe ich auch keine Fraunhofer'schen Linien erkennen können, aber als dich das Teil an meine Canon montiert habe, waren die Linien wunderbar erkennbar. Die Absorptionsbanden in Holmium dortiertem Glas sind ohne Fotoapparat mit bloßem Auge erkennbar, ebenso die charakteristischen Absorptionsmuster in Edelsteinen.Da das Spektrometer keine Skala besitzt, mache ich es so, dass ich ein Foto schieße vom jeweiligen Spektrum und dieses Foto dann (im Bildbearbeitungsprogramm) über ein anderes Foto lege, in dem man die Quecksilberlinien einer alten Leuchtstoffröhre und Fraunhoferlinien, sowie die 650 nm Linie meines roten Lasers sehen kann. Ich habe mir also selbst eine Skala in dieses Foto eingetragen. Mit Hilfe dieses skalieren Fotos kann ich zu jedem beliebigen Fotos eines Spektrums die Wellenlängen zuordnen. Mein Vergleichsfoto, das chrakteristische Linien enthält habe ich angehängt.Ältere Energiesparlampen und insbesondere Höhensonnenlampen oder besonders alte Leuchtstoffröhren (z.B. im hintersten Abstellkeller, die seit 20 Jahren nicht ersetzt wurden) haben besonders klare Quercksilber-Linien mit folgenden Wellenlängen: 365 nm 405 nm (violett), 436 nm (blau), 492 nm (türkies), 546 nm (grün) , 577+579 nm (gelbe Doppellinie) und 615 nm (rot). Bei wolkenbehangenen Himmel kommen dann noch zwei gut erkennbare Fraunhoferlinien hinzu bei 687nm und eine besonders dicke (wenn viel Feuchte in der Luft ist) bei 759 nm.Ich bin begeistert von der Qulität dieses kleinen Spektroskops und dessen Top Preis-Leistungsverhältnis. Wärmstens zu empfehlen.

Bon spectroscope pas cher
Acheté pour analyser la lumière de sources lumineuses, ce spectroscope est capable de dissocier 2 raies de vert et de nombreuses raies de jaune dont qu'on ne peut distinguer par leur couleur dans un spectre d'une ampoule basse consommation. Certaines raies du spectre sont fines, d'autres plus diffuses. Tout le spectre est visible d'un rouge assez foncé au violet mais en déplaçant légèrement l'oeil pour voir les longueurs d'onde à la limite du spectre visible.L'examen d'un spectre continu nécessite plus d'éclairement qu'un spectre de raies. Il faut bien viser la source lumineuse pour avoir une bonne luminosité.N'ayant jamais eu de spectroscope et trouvant décevant le résultat fourni par un spectroscope vendu 10 € de moins par un fournisseur d'équipements de physique pour les lycées, j'hésitais entre ce modèle et un autre 3 à 4 fois plus cher. Je ne regrette pas d'avoir choisi ce spectroscope.Je ne l'ai pas acheté pour l'examen de pierres précieuses, mais il y a une petite notice dans ce but, uniquement en anglais toutefois.
