Yes, it is difficult to use; but the effect is priceless
Yes, it is difficult to use; but the effect is priceless.This device is bloody difficult to see-through; but the image you might see, if you're patient, will show you just how effective is the light-source you're looking-at.Some years ago I was loaned an identical device, that was twice the size,; and the image was so easy-to-see that I was able to record it using a cheap, digital, camera.If you could point one of these devices at a human-being and get an image of their moral-spectrum, in the way that this device gives an image of spectrum of a light-source, we could bring-back hanging with a clear-conscience; never make a mistaken conviction ever again; reduce crime at a stroke; and drastically reduce the prison population. No! No! I've got that wrong, haven't I? I overlooked the fact that the prisons would be full again, in no time, with all the Politicians and Bankers. Children would denounce their parents and would negotiate for a Nine O'Clock bedtime. Mmmm!

Good resolution, good quality, good value.
Here is a typical spectrum of a compact fluorescent bulb. Bear in mind that the spectroscope has better resolution than the camera! E. g. The green mercury and terbium lines at around 544nm are clearly resolved by the spectroscope.I'm really pleased with the performance. Great little spectroscope. Used in conjunction with the Theremino or Spectragryph free spectroscopy programs it forms the basis of a really useful spectrometer.

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

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.

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.
