So I finally got my hands on some single crystal YAG:Ce phosphors!
Not cheap, over $300 because the minimum order quantity was 5, and they are only 3mm x 3mm.
They had some 5mm x 5mm ones too but that would have cost me over twice as much, although those would have been easier to work with.
Next items on my purchase list:
-blue laser
-blue laser driver
-blue laser lens
-blue laser protection goggles
It will be a while before I can test out the performance of the phosphors but Iām really excited anyway
Sure you didnāt āfindā those in an āabandonedā warehouse??
Canāt wait to see what you do with āem. Did you study physics or engineering by chance? Just curious.
All I know is that Saablaster claimed to be able to swap phosphor from SST-40 to XHP35. As well as to lift the die off the XHP35 package and put it on a diamond heatsink. Osram LEDs are different, but maybe he would be capable of doing a similar surgery to them as well.
Would he be willing to help you with that? I have no idea.
This light , the BFF, will beat them all. We donāt really need a measurement to know that. He is using a special bulb with an extremely high luminance that I never knew existed before.
A conservative estimation puts the throw at around 250Mcd.
Oh cool
Well I only have very rough theoretical numbers which are probably not anywhere close to real performance, but I have high hopes.
Once I order the laser and start doing intensity test of the phosphor crystal then I will have a better idea.
