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

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 .....
