help: mixed 470nm laser with 445nm laser in white RGB laser module

Updated tests.

The dot on the left is the blue from the laserlands module. The dot on the right is my 445nm M-140 diode from DTR.

However, I have no LPM to verify the output so this may not be accurate even though it looks similar. However, to my eyes, the light looks identical.

I just want people to know that this laser is not 470nm. However, the blue diode is single mode and has a fairly good circular output suggesting that it is single mode.

If it looks identical to your eyes it's not 470/473nm, There's a significant visual difference side by side.

Edit: it's probably a PL450B in there

If you can confirm that the diodes you have are within 10nm of 470nm, count me in for about 20. But I seriously doubt they're 470nm...
 
as alice said-'curiouser and curiouser' Merry ...PM coming and maybe an email to you via LLands. btw I wrote the email before i saw this thread- what I have sent should be of interest to you and LLands--

btw I still want you to send me photos of the insides..plz.. at least one with the laser modules OFF. I need to see the dichros& mounts and cube(s) and any mirrors inside.

Merry- maybe this pic from Kot will convince you-- at the bottom is a 405nm blu-ray violet laser beam the other two are 445nm and a dpss 473nm-- you can clearly see that they are not really very close in color- so the poster that compared your blue with the one from Jordan(dtr) and saw that they look the same is correct.
even if you call it a 470nm ld it SHOULD look like a different shade of blue- nobody needs a spectrascope to see that.
I tried to post Kots pic here but no amount of resizing will make this happen which is wierd as Kot was able to post it.... so go here and look and if anyone more savvy than me can post Kots pic here---plz do so for all to see with ease.

deffo not in the 470nm region, the 445 will look like purple next to a 473nm laser.
 
Here is Kots (Blord) post.

Hakzaw1 asked me to put the picture in this link. Here it goes.

For around $100 this is one great deal. Add a $25 spiro...and you have a Time Machine for under $175.

****************Hmmm-100+25= (under)$175- yeah like $50 under--lol
While I am being a stickler... Time tunnel or Time
machine is not actually accurate-- no 'time' involved-;)

with a single mirror/motor its a tunnel efx-which is a very nice efx with lots of whispy fog or smoke-(incense stick will work) (best that A/C s and fans are all off, IMO ) and $25 may be what a complete spiro may cost but I have made many for practically 0$.


Free FS mirrors (3 or 4) are inside discarded flat bed scanners- small dc motor can be gotten for pennies from battery op toys--so the only real cost is the epoxy.. If you can find(at a thrift shop) a cheap corded r/c toy you will have two motors which could be both reversable and speed controllable- so add them to a base(as close together as possible)- glue on the mirrors. Add a laser or two(three are even cooler) and you will have a deluxe spiro with full control-- put the mirror/motor that makes the smallest circle first to keep the beam(s) from going off the edges. You can combine several lasers into a small group by knife-edging them--
just keep your duty/rest cycles in mind.. its easy to lose track of time when you are in the time machine--haha ...Green pointers have zero HSing and they and 405 pointers need to be kept from overheating..
One of these LLands RGB units would make a great Spiro and there should be no rest cycle needed . If you can modulate them ttl you will get seven colors. Lots of fun for little $$..
 
^^^^^^^^^^^
Well it would not be the same-(at all)- the WFTM is incredibly small -- so some of the high price is because of that. So what you 'save' is not relevent. AFAIK only two members have been able to make these ( more than just one or two) Rog afaik did it first and Jeff (FlamP) has been doing his version for some time now- ALSO the WFTM is totally portable and yours would not be. and the deluxe version has remote control so theres that. I have seen one in person and to say you could do the same for so much less is not doing justice to the build-

when you get one done we will want to see... but I think it will be just like many that have been getting made for a long time. good luck--hak
 
Laserlands seems to be acknowledging its error now that its eBay listing. It now specifies the blue wavelength as a range "445-473nm" instead of its erroneous claim of 473nm taken from the manufacturer's site.
