I designed this enclosure for a custom broadband UV polarimeter for use in a laboratory setting. Printed from MJF, it was designed primarily for a small form factor and to be adapatable for the wide variety of projects that the Meta AR/VR labs require. The enclosure segregates stray light and is capable of adapting Thorlabs cage system elements and mounting posts. All non-3D printed hardware was sourced from Thorlabs to ensure simplicity and compatibility. The bandpass filter is easily accessible by a removable door for changing the desired measurement wavelength, allowing scientists and technicians to rapidly adjust for different laser types. 

This fixture was designed to hold two glass substrates at a very specific distance and angle relative to one another. Both mask and substrate are held to the stages with vaccum chucks, and the linear rails allow the upper stage to move up and down for switching out the sample after exposure. 

Each stage was also tilt adjustable using carbide kinematic mounts; donut magnets ensured preload on the mounts was maintained. 

The fixture was used successfully in replication patterning and proved a high-throughput concept for optical waveguide production.
