UPRtek Spectrophotometry
Introduction
UPRtek provides project-based spectrophotometry solutions for industrial, government, medical and research applications.
Spectrophotometry is used to identify materials and their characteristics based on how they interact with light: absorption, reflection, transmission, and fluorescence.
What is a Spectrometer, Spectrophotometer, and Spectroradiometer?

Most spectrophotometer applications need customization.
Over 90% of spectrophotometry applications require specialization or customization. This is because the needs are usually diverse, complex and unique for every industry.
Spectrophotometry used with Fuel Marker
Applications used with spectrophotometry might include:
- Fuel marker detection
- Supply material verfication
- Verification of printed material, banknotes, designer labels
- Pharmaceuticals validation
- Water purity analysis
- Surface color matching
- Recycled material identification
Challenges in Spectrophotometry
- The molecular characteristics of materials are complex and complicated by inherent quantum properties.
- Spectrophotometers use an internal light source, that is difficult to maintain for accuracy and stability with the correct wavelength, intensity, angle, and reflection.
- Weak absorption levels or fluorescent signals from the materials are difficult for sensors to detect and measure.
- Maintenance of spectrophotometers can be difficult and costly.
- Deployment in the field, including training is costly and complex.
- Most spectrophotometers are designed for laboratory use and are awkward for field use.
- Off-the-shelf spectrophotometers are too basic for industrial needs.
The complexities of material molecular properties.
- Materials exhibit varying molecular and quantum properties and necessitate variations in hardware.
- Liquids and solids require different types of apparatus.
- Detecting the fluorescence of various chemicals demands different types of sensors.
- Material absorption and transmission may require unique light source intensities.
- Even measuring different aspects of the same material might also require adjustable features.
Molecular properties present challenges in Spectrophotometry
UPRtek has an arsenal of options to deal with material variability, including adjustable light source wavelengths and intensities, varying detection modes, and strategies to enhance signals. Different types of sensors are implemented depending on half-bandwidth accuracy needed and sensor sensitivity requirements.
Spectrophotometry imaging is used to detect biological markers.
Measuring the reflectivity of materials.
Accurately measuring the reflectance of materials, especially those with complex surfaces or varying textures, is difficult due to light scattering.
UPRtek spectrophotometers will meticulously direct scattered light through diffusers and optical lens, converging at pinpoint sensor locations to record the appropriate reflectance with high confidence.

Measuring absorption, fluorescence.
Materials with low absorption or fluorescence levels can lead to misidentification.
For low absorption, it’s important to utilize high-sensitivity detectors and noise reduction techniques such as signal averaging and lock-in amplification to enhance signals.
Liquid based light absorption Spectrophotometry
For low signal fluorescence detection, it’s necessary to employ high-quality optical filters to filter out noise or unnecessary colors, ensuring accuracy in preserving the original fluorescent spectra. High quality sensors are also needed to detect and measure narrow bandwiths of light of single-digit wavelength nanometers.
