4. Measure the x and y values of the projected RED test pattern. Use for that a colorimeter. Make sure that the
RED test pattern is uncorrected.
5. Slightly move the adjustment screw (reference 2 Image 10-22) of the Notch Filter to a position until the
measured x and y values for RED are within the required specs (see above).
6. Display an uncorrected GREEN test pattern.
7. Measure the x and y values of the projected GREEN test pattern. Use for that a colorimeter. Make sure that
the GREEN test pattern is uncorrected.
8. Slightly move the adjustment screw (reference 2 Image 10-22) of the Notch Filter to a position until the
measured x and y values for GREEN are within the required specs (see above).
9. Repeat from step 3 until no adjustment is required and all measured x and y values for RED and GREEN are
within the required specs (see above).
10. Fasten the adjustment screws (reference 2 Image 10-22) to secure the position of the Notch Filter. Use for that
a 2.5mm Allen wrench. Make sure that the position of the Notch Filter remains unchanged while fastening the

• Clean Toraysee® cloth or any micro fiber lens cleaning cloth.
• Clean cotton cloth.

Lens cleaner (e.g. Carl Zeiss lens cleaner or Purasol® or any waterbased lens cleaner)
How to clean the Notch Filter?
1. Blow off dust with clean compressed air (or pressurized air cans).
2. Clean with lens cleaner together with a clean lens cleaning cloth to remove the dust and contamination. Use
big wipes.
3. Use a dry lens cleaning cloth to remove left liquid or stripes. Polish with small circles.

cloth. Polish again with a dry one.
