WFCAM Optics Manufacturing

WFCAM contains six major new optical elements. Five of these (secondary mirror, tertiary mirror, field lens, window and field flattening lens) were made by SESO. The aspheric corrector plate was made by AMOS.

Additionally, the science filters were manufactured by NDC Infrared Engineering and Research Electro-Optics Inc. and the auxiliary autoguider lenses by Spanoptic.
