Abstract
PURPOSE:To make construction simple by disposing image-formable light dispersing elements between the incident slit of a main spectroscope and a light source in constituting double monochromators intended for decreasing mainly the level of stray light. CONSTITUTION:Light of a tungsten lamp W and a heavy dydrogen lamp D2 is made incident via an optical path changing mirror C to a concave diffraction grating G1. The width of the light emitting part of the lamp W is about 1.5mm., and the diameter of the light emitting part of the lamp D2 is also about 2mm.. The grating G1 is turned cooperatively with the diffraction grating G2 of a main spectroscope (m) and forms the wavelength dispersed light source image on a slit S2 in accordance with the wavelength scanning of the spectroscope (m). The light of the slit S2 is made incident to the spectroscope (m), and is emitted from a slit S3 via a collimator mirror M1, the grating G2 and a telemeter mirror M2. Apertures A1, A2 are disposed to the front faces of the lamps W, D2 to shut off unnecessary scattered light, whereby the level of stray light is improved. If the grating G1 is used as a simple condensing mirror, the device acts as a single monochromator.
