Abstract

Lenslet-based integral field units are notable for the large field of view and high throughput. But the structure in the image plane of these instruments is inherently highly complex due to the spatial and spectral packing of information, and often has large dynamic range between neighbouring pixels. This may make their optical design challenging in terms of the image quality and the technological complexty. We consider design options to implement such an instrument for a 40 cm - class telescope with a focus on the fast spectrograph camera design. It is demonstrated that with a relatively simple and compact optical system relying mainly on off-the-shelf components it is possible to reach the spectral resolving power up to R390 and cover at least 3.75′ angular field. It may be reached with a Schmidt camera or a custom 5-lens objective, using a curved sensor.
