Cleaning the sensor

The sensor cleaning is a delicate and high risk operation, if you do not feel confident to do, send it to specialized people to clean it for you.

I had need to clean the sensor of my camera and I decided to clean it, as I only had a few dots of dust I tried to clean with a cotton swab with extreme care, the dots were removed without damage the sensor.

I realized the need for a device that would allow me see better the sensor, so I built a mechanism similar to a magnifying glass with light, using two converging lenses and LEDs.

The device

The device consists in a dark tube with two convergent lens with LEDs around them to give light. I used 2 biconvex lenses and 3 white bright LEDs around the lower lens.
