As a retired engineering designer I have shelves of leftover project materials that I never throw out. I have no idea when and where I acqired those pieces of equipment but I dug deep and found bits that allowed me to demonstrate complex science in a simple visual way with no need for formulae or years of university study. It seems to have worked. Thanks for the comment.
An other question i have with diode laser is there life time and efficiency over the time? I read that diode laser produce laser from a cristal. This cristal hurt with temperature and so loose efficiency. What did you think, see, about?
Hi Benjamin I have to be honest and say I don't know for certain. LEDs in general have long but finite lifetime in the order of tens of thousands of hours . However . I know from my electronic inexperience that unless you limit the current flow through a light emitting diode it can have a lifetime of just a few minutes. I have heard from quite a few diode users that after as little as a year their products have died. Ouch, that can be expensive. Sadly, I will not be using my diodes for serious work or for any significant period to see if and how the diode fails. My goal is to investigate the pros and cons of the technology . I am sure you will find a sensible answer at one of the many diode user forums.
@@SarbarMultimedia thanks for answers. Yes i find this kind of information but if you have a light mesuring tool, i'll be curious if, for same current, the light power will be the same after time. From my personnal experience, after hours for cutting a big piece of wood, the diode loose a lot of power. However, i did'nt have tool for mesuring.
i wonder where did you found those balls and springs
they are just perfect for the purpose

@@benjaminbulle9199 I have had the same problem before. In my case, cleaning the lens was the solution.
