ESD Hazard
The Raspberry Pi camera module is a sensitive electronic component and will be suceptable to ESD [3](http://en.wikipedia.org/wiki/Electrostatic_discharge) . Please take sensible precausions or you risk permanentlydamaging your camera.
Step by Step
Before you start you need to know if you want to remove the stock Infra-Red blocking filter in your camera ornot. This should only be attempted if you need to access the near infra-red capabilities of yor RPi Cameramodule.
Turn the camera module over and pull the taps on the flexi connectorto release the flexi, put the flexi in a safe place.
Gently prise the mini connectoroff the camera board.
handle the now bare cameraarray, refit this to the board. Its
better to fit the mini connector
first and let the regidity of the
flexi re-align the array to the
adhesive pad. Gently press the
arry on to the pad avoid
touching the array, use theedges only.
Add a Visible Blocking Filter
This process modifies the lens cap from the 1/3rd inch lens to take a visible blocking filter [4](http://www.ebay.com/itm/5pcs-10mm-Filter-Lens-against-400nm-750nm-808nm-1064nm-IR-Infrared-Laser-Pass-/290728770467?ssPageName=ADME:L:OU:GB:3160) . The idea is to make a cap for the lensthat can be fitted to temporarily turn any RPi module without a NIR blocking filter into an infra-red camera byblocking the visible light. Operation of a RPi Camera module with any filter will produce images with both colourand NIR content.
Using a small bladed screwdriver pierce the top of the plastic lens cap.
Work around in a circle slightly smaller than the filter
