    Nichia NUBM34T 115W 455nm

    I ran the nubm31t all 4 channels parallel at 9.412A for about a minute CH1: 2.386A CH2: 2.328A CH3: 2.436A CH4: 2.306A I was thinking of putting a ~ 4A fuse on each channel. Once one blows, the rest will blow immediately. During testing of the nubm31t, I killed a laser driver which caused...

    Nichia NUBM34T 115W 455nm

    Here are the pictures of the axis. I just bought some random XY / X stages from ebay and mounted them. If you also pair it with a Noga indicator arm, you get an insane amount of freedom. You can solder anything to your hearts content with two of these. I also included the water cooling block I...

    Nichia NUBM34T 115W 455nm

    Thank you for sharing this. I was extremely worried about the dust from cutting would get into the array. However, you shared above that there is a window to protect the array/mirrors. I am more confident in pursuing this now. I had initially thought you used some kind of chemical to soften the...

    Nichia NUBM34T 115W 455nm

    How did you remove the glue that holds the lens? I want to try to refocus my array for a tighter focus.

    NUBM31T 95W 455nm

    Yep, taobao is where the good stuff are. Also 1688 I wish I could ready Chinese!! I want to find a version with a higher input voltage. 12V is really dumb for 300W.

    Laser projector optics

    Thanks, I am learning everyday I apologize for my constant flood of questions. I know I ask difficult questions. I poke around articles all the time and what I cant find out on my own, I ask here. These videos show the transmissive type color wheels. If they do show the reflective type in a...

    Laser projector optics

    Short explanation: I want to make a laser engraver Long explanation: I want to produce a "spotlight" I will use the white light produced from the phosphor wheel and collimate it with an aspheric lens. Thank you for the posts. I had a great time reading about them. I am in contact with a...

    Laser projector optics

    Thanks for your help. I am very new to projectors and am not familiar with the terminologies used for them at the moment. I did some searching with keywords such as array, projector, phosphor wheel. But I cant seem to find what I am looking for. Most of what I find are knife edge arrays from...

    Laser projector optics

    Hello, I am researching laser projector with phosphor wheels. They usually come with diode arrays. I know some members here have taken some apart to learn about them, or to harvest the diodes. I need some advice on what type of optics they use to focus the array onto the phosphor wheel. I am...

    OSRAM 60W multilaser chip with 24 beams - JLM450nm

    Very nice! Do you use a normal spherical plano convex lens? I will soon be able to cut off the multi lens and experiment with the height once a few components arrive in the mail. Sad that express shipping takes so long these days. But at least it is still working. Any type of glue anyone can...

    Acebeam W30 flashlight/Sanwu Striker 7w blue laser: warning!

    Hello, Do you still have the W30 that may be damaged? May I purchase it from you? I want to study it because I am building my own.

    CW Laser diode Drivers - What are the important properties?

    Sorry, maybe I misunderstood the actual meaning of DSO. I thought it just meant a typical digital oscilloscope. One that measures only waveforms. Mine doesn't have the ability to measure current. My power supply does display output current and voltage, so I do have this information. ___ To...

    OSRAM 60W multilaser chip with 24 beams - JLM450nm

    On average, how much do you get charged for a machined part. For example, a 50x50x10mm block with holes and taps in it. I'm also going to get some stuff machined and the quotes I get are decent, but maybe I could get a reference from you.

    OSRAM 60W multilaser chip with 24 beams - JLM450nm

    It is mainly extremely cost prohibitive and in addition, mentally stressful of danger when you first start. Not very well documented and not sold as a consumer plug and play item. I am sure many people have found and will find your posts to be interesting and educational to read, and useful in...

    OSRAM 60W multilaser chip with 24 beams - JLM450nm

    Thanks for the beam shots. Some weird stuff going on. It is as if the multi lens is not correctly focusing or possibly the diodes do not all have the same Z height? On the 3rd picture, you can see some kind of "split beam" all the way at the top. I wonder why it does that. You may find this to...
