Christie Digital Systems Inc. is a global visual technologies leader, and offers a wide variety of visual solutions and technologies for business, entertainment and industrial applications. The company products range from small table top projectors to large 3D Cinema projectors and LCD panels. The Kitchener branch houses the Business Products (BP) Department. The teams in the BP department handle projects related to the company’s business products, such as projectors and integrated projection systems. The department wants to replace the company current high power M-Series digital projector, EasyRider, with enhanced new high power projector, EasyWash. This new projector was developed and displayed lower than nominal brightness values during testing. The preliminary analysis indicated that this issue was directly related to the lamp alignment and arc position within the lamp module. For the projector to produce maximum brightness, the lamp arc must be coincident with the ellipsoid reflectors first focal point. Therefore, this required redesigning the three axis lamp alignment module, shown in Figure 1. This will allow the lamp arc to be adjusted back into the optimal position within the ellipsoid reflector, increasing its brightness output.
Tyler B. Cater, a co-op student from the University of Waterloo, was asked to redesign the three axis lamp alignment module. The design need to allow the lamp arc to be adjusted back into the optimal position within the ellipsoid reflector, increasing its brightness output.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is co-ordinated within the Office of Indigenous Relations.
