Answer The difference is complexity. Either may be used for quantitative or absorbency purposes depending on the situation. Also of note, each may have a single or double beam integrated into it.
For clarity: A spectrometer is a general term for an optical instrument. Spectrometric methods convey a large group of analytical methods based on molecular or atomic spectroscopy. Spectroscopic instruments will typically contain a stable source of radiant energy, a transparent veil for the sample or blank, a component to separate different wavelengths of light, a detector, and a readout/processor. Photometers are simpler in design compared to spectrophotometers. They are less expensive, more convenient, easier to maintain, and good for field work. Some photometers include: visible photometers, probe-type photometers, and general purpose photometers using adjustable filters. Spectrophotometers may have a few more mirrors, slits, a grating, and maybe a filter to top if off.
Some examples include the popular Spectronic 20, Varian Cary 100, or even miniature fiber-optic spectrometers. White light from light source is directed to monochromator that selects a single wavelength, or color, of the light to strike the cuvette.
It is the incident light and represents 100% of the light striking the cuvette (Absorbs by the sample). It is the transmitted light. This is the remaining light which has not been absorbed by the solution in the cuvette and will strike the phototube or detector. The photons of light which do strike the phototube will be converted into electrical energy. This current which has been produced is very small and must be amplified before it can be efficiently detected by the galvanometer. The deflection of the needle on the galvanometer is proportional to the amount of light which originally struck the phototube and is thus an accurate measurement of the amount of light which has passed through (been transmitted by) the sample.
The principle of a spectrophotometer and a colorimeter is absolutely the same. Both use a monochromatic light to pass thorough a substance and measures its absorbance/transmittance. A colorimeter can only use one wavelenght at a time and have a fixed number of wavelenghts that can be used and they have to be in the visible range only. A spectrophotometer on the other hand can not only function like a colorimeter but also take a spectrum ie the abosorbance/transmittance of a substance across the entire wave spectrum especially if it is a UV-vis or UV-vis-IR (uv visible infra red). One can also take simple absorbance in a spec including at UV or infra red wavelenghts. Now a days very few labs have colorimeters since specs are much more useful and diverse in function YES U CAN MEASURE the optical density of your culture in a colorimete.
