More about the product
Spectroscopy is an interesting visual subject for students. This spectroscope helps teachers to demonstrate simply and clearly. Uses include:
* FRAUNHOFFER LINES * FLAME TEST IN CHEMICAL ANALYSIS * ABSORPTION SPECTRA THROUGH LIQUIDS * BRIGHT LINE SPECTRA FROM DISCHARGE TUBE Features:
* Large diameter eyepiece aperture facilitates comfortable viewing of the SINGLE, LARGE and BRIGHT SPECTRUM which is CENTRALLY PLACED in the field of view. * High quality optical components ensure that absorption bands show up clearly - even weak bands that are sometimes difficult to detect. * The LINEAR SPECTRUM is generated by a particularly bright transmission diffraction grating of 600 lines/mm. * The unit is of fixed construction - no need for adjustment. * Robust assembly to withstand years of student handling. * Convenient size. * Supplied in protective rigid box.

Pros
szép, tiszta spektrumot ad, látszanak a főbb vonlak is a Nap spektrumában. illetve a szines vonalak a fénycsovek vonalas színképében.
Cons
Az angol gyártó megtehette volna. hogy a kimenő oldalon kis szabályozást tesz lehetővé, így A szemüvegesek is élesnek látnák a spektrumot, ha a kimenő oldalon lenne egy kis állítási lehetőség. Én egy egy kb. 3 cm-es, 1dioptriás lencsével egészítettem ki a kimenő oldalon , és ha már változtattam, egy szemkagylót is rászereltem, így nem szűrődnek be a zavaró, szórt fények .
Summary
Kellemes termék, az apró "'hiányosságokat " könnyen korrigálni lehet. Véleményem szerint inkább egy egyenes látású hármas ragasztott prizma van benne. Az egykori NDK-ból hoztam ilyet (azt szét is berheltem) , emlékszem, igen borsos áron adták Spektroskop Okular néven.
