DLPDLCR2000EVM: Focus Lever Modification Guide

Part Number: DLPDLCR2000EVM

All,

We would like to present a straightforward modification to the DLPDLCR2000EVM’s optical engine that will result in a focus lever that is more resistant to adjustment. To implement this you will need:

   1x Steel Phillips Rounded Head Screw, M1.6 x 0.35mm Thread, 4 mm Long

(Part number 92005A003 on https://www.mcmaster.com/)

   1x 18-8 Stainless Steel Single-Wave Washer for Number 0 Screw Size, 0.072” ID, 0.017” OD

(Part number 99842A101 on https://www.mcmaster.com/)

   Phillips Screwdriver (PH00 x 40) or equivalent

   Wiha Precision Slotted Screwdriver (1,5 x 40) or equivalent

The focus lever can be removed by unscrewing it with the small flathead screwdriver. The optical engine does not need to be disassembled to do this.

After removing the focus lever screw, simply replace it with the Phillips screw using an appropriate Phillips screwdriver. While doing this, ensure that the single-wave washer is seated between the screw and the optical engine.

After completing this modification, the Phillips screw can be adjusted to loosen or tighten the new focus lever as desired.

Feel free to reach out if you have any questions. For discussion on this topic, please direct questions to this thread: https://e2e.ti.com/support/dlp__mems_micro-electro-mechanical_systems/video_and_data_display/f/947/t/618571
