Producto es muy bueno , pero lamentablemente no lo tratan bien al enviar , lo enrollan y queda picadas en la láminaAconsejaría que el embalaje fuese en plano y protegido ya que la lámina es muy bonita.Por mi parte estoy pensando en devolver ya que solo a quedado una pequeña parte para utilizar

Die Folie scheint den in kleinen Papprahmen erhältlichen Beugungsgittern zu gleichen Sie ist sehr gut geeignet für den Bau einfacher Spektroskope, z.B. Handyspektroskop, Pizzabox-Spektrometer...Wenn es nur um den Farbeffekt geht, ist die 1000 Linien-Folie besser geeignet. Diese wirkt viel bunter.

Nothing like what's advertised hardly any colour on it and damage marks all through it

I saw the other reviews and hoped they were just unlucky. Though the package was fine, the film arrived today looking as if it had been beat with a screwdriver and a hammer. The picture doesn't really do justice to the shape of this film. Garbage. Don't take the risk. Find someone else to buy from. Very disappointing.

以前二軸の直交回折格子を入手して、回折像の測定から~200lines/mmとなりましたが、その真偽は不明でした。そこで、本商品を入手しました。窓を見ただけですが、前のと比較して、回折像の変位量は「２〜３倍」でした。詳しくは後ほど、コメントします。# この変位の迫力は凄いです！01/06に注文して、01/14にIzgutLtdというイスラエルの会社から漢字表記の宛先ラベルのB4ぐらいの封筒(プチプチに挟まれて)「Israel post -> Japan post」で到着しました。# 最近の物流は、個人にとっても利用しやすいですね。35mmフィルムのマウントに入れて、観察の予定です。

I was thinking this product was going to be like a pair of firework glasses, not the case. It does break light up into its spectral colors, but it's only one line of diffraction as opposed to the many lines found in firework glasses.
