I inherited them from my predecessor, and yes your right, the Cube lasers are all diode lasers. I hadn't even thought about it. :thinking: I'll go and check it out again, I know they will build to order if requested.

Buy a top end OSA I'd recommend either an OL770 or Ocean Optics QE65000, test that halogen with or without the so called UV filter then come back to me with what you find. Your eye is not an optical power meter or spectrum analyser. Standard household halogen lamps produce very very little UV...

Halogen doesn't go that low, or at least any optical power un the UV is minute, we bought a batch of these so called UV blocked GU10's a while back to test this theory. I measured the spectrum of the lamp, then cut the front glass out and tried again, no difference. I then gave the glass cover...

Yes, I think your agreeing with me then that perceived white and true white are very different. My job requires me to have a coherent, collimated, polarised, continuum laser, if an RGB laser would do the job I'd be a lot better off as they are far far cheaper. I'm just trying to point out that...

I think every one will agree sun light is true white light as it makes up the whole of our visible spectrum and a lot more beyond, we can use that as our bench mark here. Any thing made up from individual wavelengths to produce white is only perceived white and not true white. For true white...

True white lasers already exist, they are made by a few company's now, but are very expensive. A true white laser is not one made up of a collection of other wavelengths, thats just an RGB source. True white is just that a continuum light source running from 400nm (violet) through to 800nm (dark...

Just stumbled upon this site, and thought I'd join. My job is playing with lasers (R&D), it mainly involves true white (supercontinuum) lasers and Acusto optic tunable filters (AOTF's). So I can at the touch of a button create any wavelength laser you want (400nm to 1800nm) with around 4nm...

True white lasers do exist, I have a 2W one that runs from 400nm through to 1800nm continuous (Super-continuum) I also have an Acousto-Optic Tunable Filter (AOTF) sat in front of it that allows me to select any wave length at around a 4nm width. The RF driver I have running the AOTF allows up...
