Pocket Hand spectroscope

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.
