LGS-4 Miniature Monochromator

Short Description:

LGS-4 is a manually operated monochromator. The entrance and exit slit can be set to 0.15 mm or 0.3 mm wide. It can produce monochromatic light with various lamps. The wavelength of the output light can be selected in microns, and one of the subdivision scales corresponds to 1 nm, a coarse mark of 100 nm. The value of the output wavelength is obtained by combining the coarse reading with the fine reading.
