Detector using when the light that is sent from light source, can all pass through sample, produce scattering, partial dispersion in the sample
Light can enter in photoelectric sensor (this is that user needs)；Through sample incident light, the detection on light source opposite can be radiated at
On locular wall, diffusing reflection is formed, partly diffusing to enter in photoelectric sensor, and here it is veiling glare in sensing chamber.Detector
Although having two ligh traps, contribute to reduce it is irreflexive, because light source ligh trap opening is excessive, diffusing reflection is horizontal also
It is very high, and make it that equipment light path is complicated, volume is big, and cost is high.
The detector of this structure, because the detector lens barrel in detector can not be well adapted for various different samples,
Prevent baseline noise of the instrument when measuring some samples with measurement the range of linearity from maintain one it is relatively good in the state of.
