A compact, large-aperture spectrograph utilizing commercially available optical components has been designed and constructed. Light is admitted through an adjustable bilateral slit and is collimated by a 300- mm ƒ/4.5 telephoto camera lens. The dispersive element is a 102×102 mm, 600-lines per mm plane reflection grating with a first-order blaze at 1.0 µ. The spectrum is photographed with a single-lens reflex 35-mm camera equipped with a 75-mm ƒ/1.5 lens. One frame covers a spectral range of approximately 8000 A with a dispersion of about 200 A/mm in the first order.
