  • Desktop Spectrometer

    Electro-Technic Products, Inc.

    The RSpec Explorer is an educational tool which makes it possible for an entire class or lecture hall to study atomic emission spectra. This is a great device for hands-on student learning including having students identify the gas in an unknown spectrum tube. Your students will find the software (included) is easy to use right out of the box. Until now, it’s been nearly impossible to teach about light and color using traditional tools like diffraction gratings because you can’t determine if all your students are even seeing the same results of their experiments. But with the RSpec-Explorer’s camera and software system, you will be confident knowing that every student is seeing the same thing.

  • Monochromators

    Bentham Instruments Ltd

    Diffraction gratings are specified by a line density in grooves per millimetre. The higher the density, the greater light is dispersed resulting in a relatively limited spectral extent. Furthermore, in general , the higher line density gratings are optimised for short wavelength use and vice versa. One must take into account the available grating(s) and the operation range of such before deciding how many gratings are required to cover a given range. Where multiple gratings are required, one can opt for a multiple-grating monochromator which would allow performing a spectral measurement over a great range, or whether a single (interchangeable) grating monochromator is used and the measurement performed in two or more parts.
