Popis: |
A simple monochromator with a 4×6 inch replica grating f: 3.4, which covers the range 365–1000 mμ is described. The dispersion is 3.55 mμ/mm in the second order and 7.1 mμ/mm in the first order. The slits are fixed in position and the wave‐length of the emergent beam is varied by rotating a mirror located between the telescope lens and the exit slit. It is useful for the production of monochromatic light with band widths of 10 mμ or more. With a 2×34‐mm entrance slit it produces 4×10−2 cal./min. of red light with a band width of about 28 mμ from a 350‐w tungsten lamp. The total energy output, spectral distribution and percent of stray light are given for various wave‐lengths and slit settings. The transmission of the instrument is given for the wave‐length range 365–800 mμ. |
