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, 115mm x 25mm.
• Supplied in protective rigid box.

DESCRIPTION:

      This visual handheld spectroscope is a 115mm long tube with a very precise entrance slit which provides a very good resolution for such product. It is very easy to use on any light source: the sky (solar spectrum with Fraunhofer absorption lines), flame test in chemical analysis, absorption spectra through liquids, bright lines from discharge tube or any desk/streetlamp...
      This handheld spectroscope is ideal to use in classroom, during scientifical public outreach or simply for you to look at street lamp differently!
