The Airy disc is named after George Airy who first described the mathematics involved in the diffraction limited function. This is also used in holography to spacially filter light.
That’s awesome Rich, much appreciatedHi LPF,
I have these diodes coming soon and I will test them accordingly . To see and justify the knee mA they are comfortable with. We all love the 405nm WL and if these last over 1W for a long period of time that's a plus. Even though its a MM diode its still awesome. This I think is what this diode would appreciate as for heat sinking, even a larger diameter sink .View attachment 64502
Yeah man I’m bad with not using an ESD strap and mat so I know what you mean, I’ve been lucky so far but their is a first time for everything so I’m sure it’ll happen one day.I killed one of these purple wonders last night and I don't know how but it's dead, not even LED it's just open circuit.....are these particularly static sensitive ? So far my other Sharp diodes haven't been although it's my fault for not using a mat/strap

I've been extremely satisfied with the beam quality of this sharp diode running on about 1.6A. After a few people asking me to confirm my preference for the 3E lens, I went back and swapped the 3E on mine out for a new G2. Now take this with a grain of salt as it's 100% subjective and not approached from a scientific standpoint, with actual measurements and calculating divergance. I still think the beam looks way tighter using the 3E lens, but I do notice there is a noticeable improvement in visibility when using the G2 lens. The added power throughput increases perceived brightness, which combined with the 'fatter' beam, definitely adds to the wow factor but doesn't look as nice to me as the 3E even still.Hi LPF.
Ok I received the Sharp 405nm diodes yesterday and did some testing this morning before work.
Well I have to say that concurring with Jordans findings that this diode has a great divergence .....
