Description
Two-Photon Polymerisation is a form of additive manufacturing (3D printing) allowing the creation of structures on nano to macro scales. Its versatility means it has already found its way into a number of fields from life sciences to integrated photonics and microfluidics. Of particular interest to astronomy is the ability to “print” micro-optics.
Here I show some of the amazing structures that can be created with Two-Photon Polmerisation and then delve into the work developing Two Photon Polymerised devices for astronomy. I detail the work developing microlenses to increase coupling into fiber fed instruments before moving onto micro-spectrographs designed as low-resolution dispersers for cryogenic instruments. I then discuss where I think some of the future applications lie.
