Long-term performance of the MLR-TT sensor: two-photon polymerization validation in the telescope environment
Robert J. Harris, Philipp Hottinger, Jonathan Crass +2
We report on the long-term optical performance of a two-photon polmerized microlens ring tip-tilt sensor. The study is backed by repeated measurements over the last six years, sinc…
2023 Astrophotonics Roadmap: pathways to realizing multi-functional integrated astrophotonic instruments
Nemanja Jovanovic, Pradip Gatkine, Narsireddy Anugu +77
Photonics offer numerous functionalities that can be used to realize astrophotonic instruments. The most spectacular example to date is the ESO Gravity instrument at the Very Large…
On-sky results for the novel integrated micro-lens ring tip-tilt sensor
Philipp Hottinger, Robert J. Harris, Jonathan Crass +16
We present the first on-sky results of the micro-lens ring tip-tilt (MLR-TT) sensor. This sensor utilizes a 3D printed micro-lens ring feeding six multi-mode fibers to sense misali…
An innovative integral field unit upgrade with 3D-printed micro-lenses for the RHEA at Subaru
Theodoros Anagnos, Pascal Maier, Philipp Hottinger +26
In the new era of Extremely Large Telescopes (ELTs) currently under construction, challenging requirements drive spectrograph designs towards techniques that efficiently use a faci…
Focal Plane Tip-Tilt Sensing for Improved Single-Mode Fiber Coupling using a 3D-printed Microlens-Ring
Philipp Hottinger, Robert J. Harris, Philipp-Immanuel Dietrich +11
Modern extreme adaptive optics (AO) systems achieving diffraction-limited performance open up new possibilities for instrumentation. Especially important for the fields of spectros…
Micro-lens array as tip-tilt sensor for single-mode fiber coupling
Philipp Hottinger, Robert J. Harris, Philipp-Immanuel Dietrich +8
We introduce a design for a tip-tilt sensor with integrated single-mode fiber coupling for use with the front-end prototype of the iLocater spectrograph at the Large Binocular Tele…
NAIR: Novel Astronomical Instrumentation through photonic Reformatting
Robert J. Harris, Jan Tepper, John J. Davenport +11
The project "Novel Astronomical Instrumentation through photonic Reformatting" is a DFG-funded collaboration to exploit the recognized potential of photonics solutions for a radica…
