輝線・暗線が良く見える
イスラエルの回折格子を買っていくつか分光器を作ってみたが斜視になるとか鮮明度悪く、とても暗線なぞ 見えなかった。本品は直線視できるし鮮明で明確に輝線・暗線見えるので驚いた。宝石用途は知らなかった。 紙への反射太陽光、パソコン画面、LED、蛍光灯等の違いははっきり判る。塩は身近にあるので炎色反応を 試してみようと思っている。嵩張らないし素晴らしい商品です。

Very small but functional unit
Ultra-compact ( easy to lose ? ) Works Okay. A curious bit of kit. Skimpy instructions.

Just right
Works well small and portable. Very nice case that fits in your pocket. Easy to take along with you to gem shows or someplace where you are buying gemstones.

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).

Works perfectly
I just so happen to have the temporary use of a similar pocket spectroscope made by Gem-A for comparison. This one works just as well as the more expensive Gem-A version. Good product if you know how to properly use it to identify gemstones.
