Spectrophotometer / Spectrocolorimeter
How to Choose a Spectrophotometer: Spectral Data, Measurement Method, Aperture and Sample Type
3nh spectrophotometers and spectrocolorimeters support color-management applications for plastics, coatings, inks, printing, textiles, packaging, food appearance, cosmetics, automotive interiors and exteriors, electronic materials, and R&D quality control. Begin selection by considering where the instrument will be used, the sample type and the color data you need.
If testing requires more than L*a*b* color data and ΔE color difference comparisons, and also requires spectral data, color evaluation under multiple illuminants or a specified SCI/SCE measurement mode, prioritize a spectrophotometer. Confirm supported measurement modes, apertures and software functions against each model’s specifications.
Suitable for incoming inspection, supplier color matching, production-line checks, on-site spot checks and multi-point measurements. For small areas, curved or concave surfaces, or textured samples, compare High-End Handheld Spectrophotometer, and confirm the aperture, positioning method and whether the sample can be held steadily in contact. If SCI/SCE is required, verify that the selected model supports it.
Suitable for R&D, laboratories, reference-color creation, measurements under fixed conditions, supplier acceptance and long-term quality management. Compare High-End Benchtop Spectrophotometer or view TS8500 Benchtop Spectrophotometer. Also confirm sample dimensions, placement and required measurement configuration when selecting a model.
Consider for powders, pastes, some liquids, samples that deform under pressure or scratch easily, and samples requiring a fixed distance or automated production-line measurement. Suitability depends on sample condition and test purpose. Compare fixed working distance, sample support, measurement speed and production-line integration. For liquids, first clarify whether you need surface-reflectance color or transmitted color.
How should you choose for transparent or translucent liquids?
For transparent or translucent liquids where the focus is transmitted color, liquid color difference or a specified color index, compare Liquid Colorimeter, and select an instrument based on the cuvette, path length and sample conditions. If transmittance is also required, confirm the selected model supports it under the required measurement conditions.
How do a colorimeter and spectrophotometer differ?
Depending on the model, both colorimeters and spectrophotometers can provide L*a*b* and ΔE. The key selection points are whether you need spectral data or a specified measurement mode, and whether the instrument meets the sample and acceptance requirements.
Routine L*a*b* and ΔE color-difference comparisons
For incoming inspection, production-line checks, batch color-difference comparisons and routine quality management without spectral data, compare Colorimeter, then confirm that accuracy, aperture and measurement conditions meet your needs.
Spectral data and specified measurement conditions
If you need spectral data, color evaluation under multiple illuminants, or customer-specified conditions such as SCI/SCE, prioritize a spectrophotometer. For reference-color management and supplier acceptance, also confirm both parties use consistent measurement conditions.
Before selecting a spectrophotometer, confirm these four points
- Whether a flat, curved, small-area, soft, powder or liquid sample is suitable for direct-contact measurement.
- Whether you need spectral data, SCI/SCE, multiple apertures, or illuminant, observer and measurement settings that match the customer’s.
- Whether the main use is on-site inspection, reference-color management, R&D analysis or customer acceptance.
- Whether you need long-term color data, batch records or a supplier-comparison workflow.
