Post # 488 WHOO


Ok So I have 2 working 488nm blocks for sale



They will come as a kit and include

•Diode block
•1 LED
•1 TEC driver
•1 10K trim pot
•1 .22UF capacitor
•1 .33 uF capacitor (salvaged but tested)
•Either 1 1 Mohm resistor and 2 3 meg or 7 1 meg
•An Ir filter
•a focusing optic
•Wiring diagram
•LM7805 (Salvaged but tested)
•1 Proto board (large enough for TEC driver chip and compensation network )

Yall are on your own to drive the diode

Kit one does 5mW when tuned correctly and is $85 Beam mode is decent but has a few satellite beams (decent for a protera laser Its garbage compared to 532nm )

Kit 2 Pending until I can test thermistor

Please note this is a very sensitive and fragile laser do not buy this unless you are very good at soldering and have lots of experience with lasers.
Wiring diagram.

Re: 488nm kits

I might be interested. Save me one for later? I'll have to think it over. Also, do you have a spectrometer test of these?

Re: 488nm kits

It generally better to not leave un-used IC pins floating. If its not going to be used, its usually better to leave it in one state where it cannot fluctuate and effectively be un-used. This usually means grounding the pin, but it depends on the IC entirely. :)

Re: 488nm kits

So basically these are some assembly required for $85, right? But I won't need any additional parts?

Re: 488nm kits

So I could get someone to make a custom host for these, and have a 5mw 488 pointer??

Re: 488nm kits

I think they're basically boxes. And I also think I am going to place an order for one of these.

Right, but in theory...I don't have the capability to run much as far as tests to make these work...so I probably won't get one. However, fascinating nonetheless.

Re: 488nm kits

I just want it for the wavelength :D Might make something portable out of it, but not much. So what happens if you run it without the TEC and just constant-current drive it as normal?

Almost You will need a driver for the diode.
However I may be able to through in an Lm317 But you will need more perf board for that

You will get IR and if your lucky a twinkle of 488 but not much

It's DPSS so it has to be exactly 488nm, right?

Yea As fare as I'm aware.

Unit one pending sale (already got pm )

Re: 488nm kits

Wait - you're telling me that these may not be 488nm at all unless we're lucky?

No im saying if you want 488nm use the TEC driver chip and tune it. :p
I tracked down these chips for that reason so use them.

These tec drivers are $82. new that's why I got older ones from other protera drivers

Re: 488nm kits

bloompyle IDK why you deleted your post but the block dimensions are ~ 25mm X 29 mm X 27 mm plus or minus 1mm

Re: 488nm kits

However, these still need the board, and TEC+TEC driver to function and that's a lot to put in a portable unit. So I deleted my post after realizing that.

If you cut a square proto board used a pen style driver and placed it under the chip in the space left by the socket then put the compensation network on the back of the proto board then it would not make the block to much longer than it is.
