would be interesting to see a picture of them all togther for comparision ?
anybody seen such a thing

In the beginning there was none. Then came the light - #1 UKLEM - 2007

Is the 445 really that blue? I was expecting a more violet shade, and colour charts seem to suggest the same. Either way, it looks like a very rich shade.
A pic on a computer screen doesn't really work too well to show the difference as a computer monitor doesn't have the depth of colour. However, side by side, 473 looks like a really dirty colour compared to 445...

To me at least, 445 looks like the most beautifull pure deep blue.
Monitors aside; the camera itself is an RGB device, therefore it can only make a representation of a colour shade based on mixed colours.
Lasers being monochromatic mean that the camera can't possibly blend an various wavelengths and produce a representative output.
It's 'B' sensors are activated, so it outputs blue at whatever wavelength its software is programmed to.

I have been using 445nm for around a year now and can assure you the colour is a beautiful deep blue, but very capable of delivering stunning violets with a touch of red added into the mix... Add a bit of green and you have some stunning cyans and light blues... And the white is something else!!!
All in all 445nm are great lasers in my book...
Like Doc says, a camera will never replace real life, but these images give you an idea...

WOW!!!! (etc, etc, etc)
my only problem with 445 is that it screws up graphic shows...
most (if not all) graphic shows are assuming you have either 473 (DPSS) or 488 (argon) for blue... so using a deep blue yields some strange looking images sometimes...
Got most of every thing in here; 405, 445, 473, 532, 543, 594, 632, 640, and 660...

The main drawback to 445nm is still the luminosity.
When you look at Mark's 1st picture, 300mw 473nm looks brighter than 500mw 445 by some amount despite only having 1/2 the power of the 445 unit.
I'd love to see 457nm brought into the mix in a picture for comparison.
I kind of see 445 as the 670, 457 as the 640 and 473 as the 635 of the red spectrum. Or to put it another way, I have a sneaking feeling 457nm is what everyones actually been looking for just as 640 was to red - dark enough to satsify graphics tastes but bright enough to satify beam enthusiasts.
Also, being a diode colour, its just a pity no cheap source of 457nm hsa come to light as I know McCarrot rates it very highly.
