Facilities

UASAL has a broad portfolio of facilities and equipment to enable quick turn around studies of new approaches to astronomical space instrumentation.

ground based observatories

UA offers a world-class research environment in ground and space-based astrophysics with strong interdisciplinary programs across the Departments of Astronomy, Optical Sciences, Planetary Sciences, Physics, and the UA Data Science Institute. UASAL collaborates closely with UA fabrication facilities including the Richard F. Caris Mirror Lab, the University of Arizona Nano Fabrication Center, the Imaging Technology Laboratory, and the Arizona Space Institute.

The Space Coronagraph Optical Bench (SCoOB)

As part of efforts to advance exoplanet imaging technologies we operate a vacuum-compatible, high-contrast testbed. Our testbed is currently configured for visible wavelengths and featuring a 952 actuator deformable mirror.

Optical Metrology and Testing

Our lab’s metrology equipment includes:

  • 4D PhaseCam 6000 interferometer
  • 4D PhaseCam 6100 interferometer
  • Faro Quantum S 7-axis 2.0m arm PCMM (portable coordinate measuring machine)
  • Optical Perspectives Group Point Source Microscope (PSM)

Thermal Vacuum Testing

Our lab facilities at Steward Observatory include a vibration isolated Thermal Vacuum Test chamber (manufactured by Rydberg Vacuum Sciences) for testing sensitive payloads within a high/ultrahigh vacuum.

  • The chamber interior is 1.2m in diameter and 2.2m in length. The usable vertical dimension with the vibration isolating optical bench installed is less than 0.5m.
  • The vacuum’s capability is as low as 1e-8 via turbomolecular pump (1e-8 Torr with LN2 cold plate).
  • The design temperature range spans from -150 C to 150 C Maximum with the temp ramp rate: +/- 2 C/min.
  • LN2: Chamber cooling is provided via LN2.
  • Minus-K 100CT-2CV Passive Vibration isolation stage

Applied Research Building

We build flight instruments in a 2000 sq foot UArizona Applied Research Building ISO7 (class 10,000) cleanroom laboratory equipped with optical testbenches and clean flow benches.

Prototyping and 3D printing

UA students should feel free to contact us if they have space or astronomy related components they would like to prototype. UASAL equipment includes: a Dremel LC40 laser cutter and 3D printers, a Dremel 3D40, and a Markforged Onyx Pro printer that allow rapid prototyping. A far

Custom Microfabricated Optics

UA is home to multiple micro and nanofabrication facilities used by our lab, including https://mfc.arizona.edu/ and the SC Micro/Nano Fabrication Cleanroom. We have developed processes for fabricating optics in silicon nitride membranes on silicon wafer substrates, such as precision micro-scale pinholes Jenkins et al 2023, figure below and combination reflective Lyot stops/self coherent camera masks.

Ground-based Astronomical Observatories

Steward Observatory is a partner and home to a wide range of world-class observatories, among these are the Large Binocular Telescope and 6.5m aperture telescopes located in both the northern and southern hemispheres. For details see our observatories page.
