White light discussion tends to focus around spectrums of perceptual/blackbody/the sun importance because... well, it's just the natural choice. Is there a name for a light source which has a constant emission intensity across a given range of wavelengths? Does such a thing have any practical purpose (beyond being interesting to think about) and do we actually make anything capable of producing such light output? I suppose one way might be to take some incandescent source and then stick a really well tuned filter in front to "level out" the normal curve, but that punts the problem to constructing such a well tuned filter.

The issue with this is that you can’t necessarily define ‘constant’ in a meaningful way. Being a density function rather than a point function, the energy irradiance from a source changes changes depending on whether you measure in terms of wavelength or frequency.

- zamadatix 2mo agoI'm not sure I follow why the density function can't be constant over the interval any more than it can be the usual slanted bell shape it is? I'm more than fine that the actual light is sampled out of this in quantized bins and amounts, that shouldn't be any different than any other light.
