### 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. Available equipment includes: a Dremel LC40 laser cutter and 3D printers, a Dremel 3D40, and a Markforged Onyx Pro printer that allow rapid prototyping.

### Optical Metrology and Testing

Our lab's 4D PhaseCam 6000 interferometer allows vibration insensitive metrology of optical systems such as space telescope assemblies as well as testing of individual optical components on nanometer scales.

- 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.
