Yes the item is made of metal tubes and plastic ends which in the picture seems OK but when it's in your hands the prospective changes. The finishing is passable but the two tubes the slides into each other (for focus) are loose and does not give you a good feel when you extend / retract them. They are also held together by a cheap screw that acts as the sliding guide. The Opening slit where the light enters the Spectroscope is way too big so no matter what type of light you are looking at, it all look the same. Save your money. I tried to select 1 star in the options but it will not let me so I added it to the title of the review.
El espectroscopio educativo muestra un pequeño espectro producido por tres prismas, se necesitan mejoras.
Necesita ser reparado, mal ajustado eyepiece, ranura demasiado ancha y la imagen completamente fuera del centro. La ranura ajustada y la diapositiva es visible, pero el ancho es muy pequeño. Teniendo en cuenta el precio, pero una calificación positiva.
Is een prima product voor simpele experimentjes
I would recommend. Good build quality and works as expected
Nice design for small hand held spectroscope. Brass with glass lenses. Slit aperture way too wide. Good internal crystal produces nice wide spectrum. Needs to be better handled by vendor and shipper. Arrived with broken eyepiece lens, detached lens cap, detached slit aperture.
