AstroMedia modell: spectroscope

The spectroscope contains a 900 lines/mm refraction grating and is able to project the spectum linearly. Thanks to the careful design done by German firm Astro-Media the position of lines can be determined up to 5nm precision. The diffraction grating is available separately as well.

The demonstration grate has 89 X 32 mm size, each aperture size is 16 X 9 m. This slide includes 3 rulings of 100,300,600 lines/mm.
