FEELER CNI 561nm 5mW pointers.

Re: GB CNI rare/special wavelength pointers and other stuff.

So, what frequencies? What is so special about these frequencies? How much per unit for those who kick in?

Also, and this question is not for everyone....I am interested in a special designed host for a project, a commemorative of sort of in a special shape. I wonder if they can do something like that.

I thought all these laser everyone has are diodes of the DPSS type. (It has been a long time since I studied physics:):):)

they are not commonly available. 589nm is bright yellow, 473 is bright sky blue.

561nm is weird, its like half-ripe banana colored but whats important is that it is nearly at the peak of human sensitivity to light. a 5mW 561nm laser is going to be brighter than any other laser at 5mW (except lasers closer to 555nm) and no, i do not believe CNI can do that, they are focused on lasers not hosts.

also, you may want to do some further reading on diode and DPSS lasers.

The prices for the lasers are listed on the OP. 589 & 473 aren't nearly as special as 561 is, since those are more commonly available(though still quite rare). 561, is easy to produce but it's limited applications are what keep it from being mass-produced & common:)

Re: GB CNI rare/special wavelength pointers and other stuff.

Now I remember. It all about the crystal! (DPSS) Yep, crystal meth is expensive though illegal...just kidding.

Other than the colors, considering that the DPSS are less stable, is I guess it is just about their being a bit unusual...

Why not save some money and simply get the DPSS as a module. I did not check to see if they were available. Wouldn't it be cheaper to build them ourselves?

As long as you guys are here, just for the heck of it, it was so cheap, I purchased this: Focusable 532nm 100mW mini Green Laser Pointer/ green laser torch burn matches-in Laser Pens from Computer & Office on Aliexpress.com | Alibaba Group

However, I am concerned about something. I have no idea how much IR it produces. I will not operate it indoors until I get the proper eye protection but that is the problem...how to protect against IR....also how to test for it?

The other thing is I have been looking for a decent calibrated sensor so I can build a power meter....but they are pricey. (NIST is actually less than a mile from me....however 1) I don't think they would do this for me and 2)considering the terrible job they did on building 7 of 9/11 notoriety...I don't trust them:cryyy:
 
Re: GB CNI rare/special wavelength pointers and other stuff.

I always ask, but please see if they will sell empty/blank GLP hosts (the larger of the 2sizes). I recently got one from a member and find my self really really wanting another- all im going to day is theres room for a 1W red and beam correction inside :whistle:

They are proposing to get some <5 mW pointers of wavelengths unavailable form anywhere else from CNI--see: Green laser, Blue laser, Infra Red laser, IR laser, UV DPSS laser.

"Changchun New Industries Optoelectronics Tech. Co., Ltd. (CNI), founded in 1996, is the largest manufacturer and supplier of diode pumped all-solid-state lasers (DPSSL) in China. CNI produces CW, modulated and Q-switched laser modules at different wavelength, including UV, visible and Infrared. These lasers are widely used for industrial instrumentation applications in holography, biomedical, fluorescence, reprographics, laser trapping, interferometry, semiconductor inspection, laser show and material processing. In addition, CNI has the capability of laser device design, optical coating, device fabrication, component assembly and system integration. CNI is ISO-9001, FDA, CE, RoHS and JQA certified."

Any chance they can do some of the other rare WLs on that page? Many of those are far more interesting than 561nm.

Maybe someone could ask for a full list of WLs they can do in portable form?

Ill add that to the list of possibilities. LeHap can you check on that?

Sure.

I know they can do the following so far in GLP host.

405nm
447nm
450nm
473nm
510nm
520nm
532nm
561nm
589nm
593.5nm
635nm
640nm
650nm
660nm
671nm
808nm

Etc... any you guys want me to ask?

@spaz

You want a GLP host correct? I'll send CNI a message :)

Please ask them if they can/will do all of those in a PGL-III-M host, which Dragon Lasers Spartan is, for a little bit extra cost. Dragon Lasers sells the 5mW, Spartan for only $30 more than the GLP version and that is a retail price.

Maybe CNI would do for less---the PGL-III-M host has more mass and better heat sinking and duty cycle I assume.
Maybe ask about it? Does the PGL-III-M host have a better/longer duty cycle than GLP does for any given wavelength laser with a 5mW output and can they make the listed wavelengths in a PGL-III-M for a small additional cost if people would prefer that host?

Just a thought while everyone is thinking to spend approx $300 ---$20 or $30 more for a host upgrade would be a nice option to have.
 
Re: GB CNI rare/special wavelength pointers and other stuff.

Ok, asked person at CNI if they can do a bare host(PGL-III-C), along with possible wavelengths in GLP host.

Ask about the PGL-III-M also---they get a lot of money for the PGL-III-C host--I assume not so much for the PGL-III-M as in DL Spartan which is only $30 more than GLP for 5mW 589. Ask about both --is not money until it is money. At least we know all options.

Ok, following info from CNI:

Bare PGL-III-C module is $80USD.

Do you guys have any wavelengths you were looking for in the GLP host? It will make communication between CNI & me easier :)

Cool, thanks. I had in mind these:

UV
355
360
375

violet-blue
415
435

cyan
480
488
491
500

orange
604
607

But better let them give a list than ask for each one of these ;)

In which host?

I know 604/607 is not practical so those are gone, same with 500 :p

How much do you have to spend? I don't want to bother CNI with pointers which will cost $x,xxx's for us. Needs to be realistic :)

I'm curious about 561nm in a PGL-III-M
 
Re: GB CNI rare/special wavelength pointers and other stuff.

Yup, count me down for at least one 561nm pointer. I have to start filling that gap between 532nm and 589nm...
