Abstract

We present a conceptual design for a low resolution optical spectrograph for the Astronomical Observatory of Cordoba 1.54m telescope. The simple instrument is required to cover a broad wavelength range (4000A<λ <9000A with 3000A simultaneous coverage) at a resolution of R=λ/∆λ ~ 500, allowing its use as a versatile astronomical spectrograph. In particular, we explore the use of inexpensive commercial off-the-shelf lenses, gratings, and a CCD system to create a small and simple spectrograph that has reasonable performance. We carefully measure properties of the lenses and demonstrate that they have excellent image quality and high throughput.
