Shanghai Jiepu Technology's high-sensitivity UV absorption instrument detects water or flue-gas pollutants. An imported flashing xenon lamp provides stable output for over 5 years of continuous use. Concentration measurement: 1. Turn off the source and collect electronic noise. 2. Turn on, set 100ms exposure and collect the reference. 3. Place the sample and collect its spectrum; X is wavelength and Y transmittance. 4. Absorbance = Log10(T). Beer–Lambert formula: A=-log10(T transmittance)=Kbc. A is absorbance; T is output intensity I divided by incident intensity I0. K is molar absorptivity, depending on substance and wavelength λ. c is concentration in mol/L; b is absorbing-layer thickness, with the unit unspecified. L can replace b with the same meaning. Example: UV absorption under the national standard quantifies oil in water. The figure shows a fully linear concentration response at 260nm.

Transmission measurement system. SpectrumFactory professional processing software: 1. Transmission/reflection measurement of glass or transparent objects; 2. Raman spectra with a laser; 3. UV absorbance with a xenon lamp and liquid concentration from Beer-Lambert law; 4. Automatic one-, two- or three-axis stage and microscope-motor control, autofocus, cameras, stitched spectra, circular-arc acquisition and S-curve acceleration/deceleration; 5. X-axis time-series stability testing with a mercury-argon lamp; 6. Y-axis time-series testing of laser center-wavelength stability; 7. Motorized microscopy for transmission/reflection and Raman hyperspectral imaging; 8. LIBS metal-composition measurement with a 1064 Nd-YAG laser; 9. Film thickness 5um-100um; 10. Colorimetry including XYZ, Lab, Yxy, HSV, LCH and RGB; 11. Remote online spectral measurements; 12. Uniformity testing, including pharmaceutical granules and LED illumination. Exceptional stability: Industrial-system stability combines spectrometer and source stability. Spectrometer intensity stability >99.99%; wavelength accuracy +/-0.5nm; wavelength temperature stability; wavelength repeatability. Halogen-lamp stability >99.9%; after 15-minute warm-up, lamp stability >99.9% and complete-system stability >99%, measured over 8 hours. UV absorption OEM module: Includes a fiber spectrometer and flashing xenon lamp. The spectrometer integrates xenon control, requiring no external module, and an internal calculation module directly outputs ABS absorbance without host-computer calculation.
