In this Patreon exclusive for patrons I will test some laser related items donated by... patrons.

Thanks to Piter Soft for sending a home-built laser based on a laser diode from a DVD burner. I will test the power and wavelength of it.

Thanks to zedd for sending an inexpensive infrared filter from eBay and the "filter" that was replaced in his high-powered green laser pointer. I will test how well they filter infrared. I am bit surprised by the result...

At the end there is also a teaser for my next public video. Planned for release on Friday, July 31st.

Good Summer to all fellow Northern Hemispherers! And good luck with the winter for the rest of you. The weather in Denmark is like autumn at the moment...

Testing eBay infrared filter and homebuilt laser

I have received some laser related items from patrons to try out. A homebuilt laser based on a DVD burner drive and an inexpensive IR filter from eBay. I will do some testing on the power and wavelength of the laser and some spectrum testing on the IR filter. Will such an inexpensive filter be any good?
