Freeform Wide Field-of-View Spaceborne Imaging Telescope: From Design to Demonstrator.

Wide field-of-view imaging optics offer a huge potential for space-based Earth observation enabling the capture of global data. Reflective imaging telescopes are often favored, as they do not show chromatic aberrations and are less susceptible to radiation darkening than their refractive counterparts. However, the main drawback of reflective telescopes is that they are limited with respect to field-of-view while featuring large dimensions.

Miniature freeform flow-line lightguide for sensing: from design to fabrication.

We present the development of a compact (about 1.3 × 2.0 × 20 mm) freeform optical lightguide for sensing applications, from the conceptual design to the fabrication through injection molding.
