What it is

The Perkin Elmer Lambda 750 is a double-beam, double-monochromator, ratio-recording UV/Vis/NIR spectrophotometer.^[2]

How it works

General reference — not yet source-verified

In a double-beam spectrophotometer, light from a source is split into two paths: one passes through the sample and the other through a reference, allowing real-time compensation for fluctuations in source intensity.

Where it fits in the process flow

General reference — not yet source-verified

Spectrophotometers are used in quality control and research laboratories for analyzing the optical properties of materials, such as transmittance, reflectance, and absorbance. In precision optics, they characterize filters, coatings, and other optical components.

Applications

General reference — not yet source-verified

UV/Vis/NIR spectrophotometry is applied across chemistry, biochemistry, and materials science for quantitative analysis and characterization.
