589nm vs. 593.5nm Pointers?

[NightExplorer96]

Well.....

I love going back reading these kinds of threads over LPF when I get bored and the fact I'll be back in the zone ordering a 405nm pointer from Laserglow tomorrow early morning made me want to start this thread

How come 593.5nm pointers are so much rarer then 589nm pointers? Is it due to popularity? price? newer technology? visibility? color(although it's a very small difference)?

I mean, we see tons of 589nm pointers(ok, maybe not tons) but many people have 589nm in their collection, whereas 593.5nm is still quite rare :undecided:

Discuss

Also, which would you rather have? I personally, would rather have the good'ol Rigel

593.5nm all the way as my favorite color is orange and this was very close. IMHO it is not yellow but an amber/orange color. Some cameras see it as almost a pure yellow though.

Indeed! 593.5nm is such a nice, calming color

maybe because 593.5nm are very inefficient compare to 589nm..... cost more to produces+less profit margin.... And as we all know Companies prioritize profit before any other factors...

Good point! :yh:

Edit: 593.5nm pointers are cheaper at lower levels actually.

589 is just easier to produce, slightly higher visibility, more stable, and available in higher powers. Or so I'm told.
EDIT: but 593.5 is such a nice colour tho...

Is there a noticeable difference in colour between 589nm and 593.5nm?

From what I've heard, yes.

This is a fairly accurate photo of a Dragon Laser 589nm 50mw and a CNI PGL 30mw

 

[NightExplorer96]

Ugh.....

Such nice pictures bruce! I'm starting to think 589nm might be better for completing a rainbow since it's more on the yellow side of things unlike 593.5?

Keep this going

Yes there is a noticeable difference even though there is just a 4.5nm difference between the two.

For only 4nm there is quite a bit of a difference.

Left is a 594 HeNe which is identical (to my eye at least) to 593.5 and right id 589. It's a bit over exposed but the colors are pretty close to spot on.

593.5/594 is an amber color since it's getting into the orange wavelengths where 589 is pretty much a golden yellow.

 

[Gabe]

Is 589 really that yellow? I have a 593.5 as well and the colour for that one is spot on. But I never remembered 589 being that yellow

 

[Pman]

593.4 because I already have a 589
I showed 3 people my 589nm at the same time awhile back and the answers for what color it was was never straight yellow. It was yellow/orange, orange, golden or golden orange. It can make a difference when you change the background or of course having another wavelength next to it or particles in the air. Especially nice when a beam has that "shimmery" look like it's sparkling everywhere.

 

[diachi]

Huh, TIL. Wouldn't have thought there would be that much of a difference, cool!

@Pman: That "shimmery" look is my favourite - for any wavelength.

589nm is a real oddball wavelength for me to photograph and have come out accurate. By itself works pretty well:

Or this view:

But as soon as I added other wavelengths with it, I was amazed how orange it now looks in my photos:

To me the closest pictures I have to what it looks like to my eye is the top one and the crystal photo. I feel it is a golden yellow, if I lase a white wall with ambient light present, to my eye it is a beautiful golden yellow.
