photospectrometer vs spectrophotometer... which is the standard term?
Nathan McCorkle
photospectrometer = a measuring device that captures a spectrum of
signals, with photons as input
spectrophotometer = a photon measuring device that captures the
spectrum of the signal

Spectrometer is a more fundamental idea, onto which you can add the
narrowing filter of mass or photons or radio waves or sound waves, etc.
So the words with Spectrometer in them seem more natural languaging to me.

(5,510,000 hits vs 17,100).
Wikipedia says spectrophotometer/spectrophotometry.
Nanodrop also calls their boxes spectrophotometers.
That's good enough for me...

Google says spectrophotometer is by far the more common term
(5,510,000 hits vs 17,100).

seems like good logic

Those numbers are roughly the same as a percent of the total combined
hits (%99.69 vs %99.43), so both make sense.
Thanks!

spectrometer
I rarely hear anyone put photo in there either on the front or the
middle.

Photometers came first then, when the ability to take full spectrum readings rather than use filter based technology arrived, someone plonked the spectro bit in front to differentiate their technology from the preceeding one.

but if you mean UV/Vis then that "spec" refers to spectrophotometry.
That's how I view it. Depends on the technology and context. Yea,
spectrophotometry is long to say but in writing, I use the full form
so that there's less confusion

plate or some other instrument?) and when was it invented? Wikipedia
says the first photometers were merely the human eye judging the
intensity of a sample.
Newton's prisms didn't disperse light enough for him to really make
measurements, but Fraunhofer invented a 'spectroscope' in 1814
(published on it in 1817, "Determination of the Refractive and
Dispersive Indices for Differing Types of Glass in Relation to the
Perfections of Achromatic Telescopes")... the meter part of his device
was merely present/absent, he didn't really care about intensity.
So if you consider the eye as a photometer, then I guess it came first...
