Hi likevvii, Do you have the same Osram chip as me? On your hand made pics to post 128 it looks that you have one with 20 beams, not 24.Alright guys,
Here it is. Nichia VS Osram. (Nichia NUBM31T 95W VS Osram PLPM4 450 - 60W)
This is my first time doing a beam test. I did what I wanted to do.
Driver used: MDP-XP w/ 4 modules
Note: Nichia = made in Japan, Osram = made in China.
Driver for nubm31t?I am not sure. This is what I can calculate for you:
Nichia nubm31t 95W @ 1.8 x 1.2mm = 44W/mm2 power density
Nichia nubm44v2 7W @ 0.2 x 0.2mm = 175W/mm2 power density
The nubm44v2 has much more power density. But 9% of the output of the nubm31t. Need to consider what you plan to cut. If you need clean and precise cutting, seems like nubm44v2 is still the best.
However, maybe things like metal or stone needs raw output, this may do the job?
There is a way to farther reduce the spot size. You need to modify the multi lens and slightly increase the height and farther away from the diodes.
If you are interested to test this, I can refer you to a laser seller with a suitable driver for 50USD (new) and could sell you my osram plpm4 450 for cheap lol
If one day I buy NUBM31T I would try something like this driver.Driver for nubm31t?
