Box with Diffuser Slit

This is a four-sided box with a built in slit for the insertion of a light-diffusing material, such as tissue paper.

This print was developed as part of a project creating a classroom-accessible goniometer, which can be used to measure the contact angle of liquid droplets on a surface. This box is designed to block out stray light and allow for even illumination of the droplet from behind using the diffusing material.
