20.3.9 390 RGBY Converging Lenses
Each TI Loop is equipped with 2 Converging Lenses, one at the entrance and one at the exit of the loop.
• NOTE Always use finger cots or gloves when handling lens elements
• NOTE direction of lens when reinstalled. The flat surface should be facing outwards towards Laser cluster,
curved/concave side in.
• NOTE direction of clip when mounting. The four (4) center flaps should point inwards.
Location of the converging lenses
To get access to the converging lenses, the TI loop must be released and pulled out.
At this point the TI loop is actually mechanical released, but in order to pull it out, two more screws has to be
removed to give more space, see illustration.
It is now possible to pull the laser cluster/ interface towards the side of the projector some millimeters, and by
that it is possible to pry the TI loop out. It is a narrow space, but it is possible. (Be patient!)
