Un producto pequeño pero puede mejorar para ver el espectro de luz, resulta un poco difícil verlo

L'instrument par lui-même peut marcher à condition de savoir précisément comment s'en servir. Or aucun mode d'emploi ni notice. Même sur le site du fabricant il n'est pas clairement référencé. Sur YouTube on trouve une "démonstration" mais en japonais (ou chinois?) donc incompréhensible pour la plupart des occidentaux dont je suis. De plus c'est mal filmé (de trop loin) et on ne distingue pas bien ce qui se passe. Plus encore, il est mis en œuvre un système d'éclairage très très lourd (fibre optique?), qui, s'il est nécessaire, grévera fortement le prix de la mesure du spectre. À revoir complètement, même la description de l'instrument sur Amazon est indigente. J'aurai dû mettre 0 étoiles.

Small and handy, I use it,for checking spectral output of modern lighting systems. Particularly examining high blue emission.
