Description
ELMER is a multi-purpose Camera&Spectrograph in the optical range for the GTC. ELMERs electro-mechanical design was based in well known, straightforward and reliable solutions, hence each mechanism is based in a wheel driven by a pre-loaded worm gear transmission, except focusing of the focal plane on the CCD which is based in a translation stage. All mechanisms are driven by the same stepper motor type with an incremental encoder, being commanded each one by a local control unit. After integration, an intensive campaign was carried out at factory for testing the functionality and performances of each mechanism. We present the electro-mechanical design of ELMER and the resulting performance after factory tests.
