Step 4 Disassemble the lens enclosure

This lens unit will probably unscrew apart into two pieces (used for focusing). The section which attaches to the PCB is probably the spacer, and only holds the other section with the lens in a set distance from the main light sensor, however the filter we are after could be in the connecting part too (you will probably work out if it is if you can't find the filter in a minute).
