Re: new Sharp 495nm diode(after testing it confirmed just 488nm)

Re: new Sharp 495nm diode

I wouldn't say much more. My guess is this is sitting at 490nm. It's a little greener when compared side by side, but indistinguishable alone.

Re: new Sharp 495nm diode

Are these 488 diodes rejects or legit scientific samples? If so, some suppliers aren't going to last long with 488 diodes at 2k retail price when we can go on eBay & get one for $300! op:

Re: new Sharp 495nm diode

I have no idea. I hope sharp is trying to compete with the other big two.

Also, I think it's fair to call this one cyan. It's green sometimes, and blue others. Kinda like the 561 I had was both green and yellow. It's almost irritating to have because of it...

Edit: When not focused to infinity the best I can, there is a strange artifact like CNI described... you don't notice it unless you're right up against it though.

Re: new Sharp 495nm diode

When will we be seeing pictures of your 490nm?

That would probably make my OCD go into overdrive. Good thing I don't have a 561 in my collection.... yet

That's very bad news. I was hoping that was a one diode problem. I'd like to try figure out what is going on with this diode.

Re: new Sharp 495nm diode

Whenever I can find a camera that I don't need to do too much photo editing with. Hopefully soon... I want to review all 3 of the new sharp diodes.

Edit:


I found a tool in paint.net that lets me at the very least accomplish editing this properly... I just need to be a lot more precise than this edit.

Color is fairly close on my monitor.

Re: new Sharp 495nm diode

drool! that is one hunk of a laser beam. I need to see that in person!

It looks like a full on scifi movie prop

Re: new Sharp 495nm diode

I wonder where it will measure in wavelength. Can't really tell by eyeing it.

Re: new Sharp 495nm diode

How about just a normal beam shot without editing just to get an idea!

After all I just bought one!

Your just going to use a nano boost on it yes!

 

[ZRaffleticket]

Re: new Sharp 495nm diode

It was in a self contained fog machine. Did that for better color in the pic. I'll take a new one without any fog when I get back from my buddy's place!

Edit: yes this is running a nano

Re: new Sharp 495nm diode

Funny thing, that color actually looks closer to my pushed NDB7675 than most "cyan" laser pictures I've seen so far.

Re: new Sharp 495nm diode

That's the bad thing about monitors. They all look differently and none give you the same color as another every time. What my laptop "sees" as the color may be way off from someone else's computer monitor shows.

Re: new Sharp 495nm diode

Just a note: editing the picture earlier was only to change the hue from deep blue to light blue.

Before Edit:


After Edit:


Noticed something with my laptop monitor. When I look at the screen top-down, I see it looking blueish, and bottom-up it looks greenish. Kinda like how the thing actually appears in real life. Neat.

 

[paul1598419]

Re: new Sharp 495nm diode

Yeah, Zach. With your camera it seems all blue colors look the same. The unedited one could be a 445nm as far as I can tell.

Re: new Sharp 495nm diode

^That is a very nice color! I see you are growing your collection again Z, exciting! All these diodes are making stuff much more affordable for us!
