Diffraction Spectroscope Pocket Model

A compact lightweight spectroscope for personal use by gemologists and scientists working in the field. Uses include: Spectrum from a fluorescent bulb. Gemstone analysis. Flame test in chemical analysis. Absorption spectra through liquids.  Features: High quality optical components ensure that absorption bands show up clearly - even weak bands that are sometimes difficult to detect. The spectrum is generated by a particularly bright transmission diffraction grating of 600 lines/mm. Fixed construction - no need for adjustment. Robust assembly to withstand years of use. Pocket Size: 55mm x 12.5mm. Boxed Weight: 30g. Supplied in protective rigid box. IMPORTANT: Do not use to observe the Sun directly. Doing so can be very dangerous. You can however observe blue sky though the spectroscope and will see Fraunhofer lines.
