	Spectrophotometry - Wikipedia, the free encyclopedia
		Spectroradiometers, which operate almost like the visible region spectrophotometers, are designed to measure the spectral power distributions of illuminants in order to evaluate and categorize lighting for sales by the manufacturer, or for the customers to confirm the lamp they decided to purchase is within their specifications.
		The most common spectrophotometers are used in the UV and visible regions of the spectrum, and some of these instruments also operate into the near-infrared region as well.
		Historically, spectrophotometers use a monochromator to analyze the spectrum, but there are also spectrophotometers that use arrays of photosensors and, especially in the IR, there are spectrophotometers that use a Fourier transform technique to acquire the spectral information in a technique called Fourier Transform InfraRed.

	HP 8452A spectrophotometer
		The HP 8452A Diode-Array Spectrophotometer is a single-beam, microprocessor-controlled spectrophotometer.
		In a conventional spectrophotometer, polychromatic light from the monochromator is transmitted through the sample, and the sample absorbance is determined by comparing the intensity of the light hitting the detector with just a sample blank with the intensity of light hitting the detector with the sample in place.
		With a diode array spectrophotometer, polychromatic light passes through the sample and is focused on the entrance slit of the polychromator (the entrance slit and dispersion device).

	Datacolor - Color Management Solutions
		Spectrophotometers designed specifically for the measurement of colored materials, are at the center of any modern color formulation, color production, or color quality control system.
		Although these color spectrophotometers are designed to measure samples both accurately and repeatably, they accomplish these measurements only within a range of applicable tolerances.
		Spectrophotometers are not perfect measuring devices, and how well they measure is often dependent upon factors under the control of the system operator.

	Spectrophotometry Pre-lab Exercise
		A spectrophotometer is an instrument designed to detect the amount of radiant light energy absorbed by molecules.
		Sections of the projected spectrum can be either blocked or allowed to pass through the slit so that only one wavelength will pass to the other sections of the spectrophotometer (The position of the grating is adjustable so that the region of the spectrum projected on the slit can be changed.).

	How does a reflectance spectrophotometer work? (Site not responding. Last check: 2007-11-06)
		Reflectance spectrophotometers measure the amount of light reflected by a surface as a function of wavelength to produce a reflectance spectrum.
		The reflectance spectrum of a sample can be used, in conjunction with the CIE standard observer function and the relative spectral energy distribution of an illuminant, to calculate the CIE XYZ tristimulus values for that sample under that illuminant.
		The operation of a spectrophotometer is basically to illuminate the sample with white light and to calculate the amount of light that is reflected by the sample at each wavelength interval.
