Description:
A spectrophotometer measures either the intensity of light reflected by a sample or the light absorbed by it. A double‐beam spectrophotometer facilitates comparative measurements. The double‐beam UV-VIS spectrophotometer exhibits a stray light level of ≤0.05%T (at 220 nm and 340 nm) and can be upgraded without difficulty.
