YL4520 45°/0° Non-contact Spectrocolorimeter
YL4520 Non-Contact Spectrocolorimeter | 45°/0° Measurement for Color Quality Control
The YL4520 non-contact spectrocolorimeter uses a 45°/0° optical geometry. Its measuring probe remains separate from the sample, making it suitable to evaluate the color of liquids, pastes, powders and other materials that are difficult or undesirable to measure by direct contact.
The instrument can be evaluated for laboratory work, R&D color matching, sample color-data development, automated production-line color measurement and quality control. Potential application sectors include cosmetics, fruits and vegetables, food, plastics, electronics, paints and coatings, inks, printing and ceramics. Before implementation, confirm sample form, surface condition, fixed measuring distance, container or fixture, production speed, installation space, communication interface and the actual quality-control workflow.

Key Features of the YL4520 Non-Contact Spectrocolorimeter
The YL4520 is intended for applications that need a defined 45°/0° measurement geometry, reduced influence from direct sample contact, and consistent color data for comparison and quality-control workflows.
45°/0° Optical Geometry
The YL4520 uses uniform annular illumination at 45° and receives the reflected signal at 0°. This geometry can be used to compare surface color, establish CIE Lab color data and evaluate color differences under a consistent measurement setup.
Non-Contact Measurement
The measuring probe does not need to touch the sample. This can reduce probe buildup, contamination between samples and surface disturbance when evaluating liquids, pastes, powders or other materials that may adhere to a contact probe. The degree of benefit depends on the sample, its container and the measurement procedure.
For Laboratory and R&D Color Management
The instrument can be evaluated for R&D color matching, sample color-data development, batch comparison and color communication workflows. Keeping sample preparation, positioning, distance and calibration consistent helps teams build comparable records and apply their internal color standards.
Can Be Evaluated for Automated Color Quality Control
Depending on the production setup, the YL4520 can be considered for automated color measurement to track batch differences, process color changes and product color status. Integration should be evaluated against the line layout, sample positioning, measurement timing, communications and the site's acceptance rules.
For a Range of Materials and Industries
Potential applications include color inspection in cosmetics, fruits and vegetables, food, plastics, electronics, paints and coatings, inks, printing and ceramics. Suitability should be confirmed with representative materials and actual process conditions.
Helps Reduce Direct Probe Contact
Because the probe does not directly contact each sample, non-contact measurement may help reduce residue transfer between measurements. This can be useful to evaluate for foods, cosmetics, liquids, pastes and powders that tend to leave material on a probe. Follow appropriate sample-handling and cleaning procedures for the application.
Applications to Evaluate
Liquids and Pastes
Consider the YL4520 for liquid and paste samples that are inconvenient to measure by direct contact, may adhere to a probe, or require a measurement process that avoids probe-to-sample contact. Keep the container, fill level, surface condition and measurement location consistent.
Powders and Granular Materials
The instrument can be evaluated for powders, granules and materials that are difficult to measure by contact. For repeatable comparisons, keep the sample surface, fill height, particle distribution and sampling procedure as consistent as possible.
Laboratory and R&D Work
Potential workflows include R&D color matching, sample comparison, batch data management and establishing internal color standards. Define the sample preparation, positioning, calibration and reporting method before comparing results.
Automated Color Quality Control
Where the equipment and measurement conditions permit, the YL4520 can be assessed for automated color measurement, process monitoring and quality decisions. Validate the full workflow at the intended installation site before relying on it for production decisions.
Common Application Sectors
Cosmetics, fruits and vegetables, food, plastics, electronics, paints and coatings, inks, printing and ceramics.
What Non-Contact Color Measurement Needs Can the YL4520 Address?
The YL4520 may be appropriate to evaluate when an application needs 45°/0° optical geometry, non-contact measurement, analysis of liquids, powders or pastes, laboratory R&D, or automated color quality control. To compare another 45°/0° model, see the YL4560 non-contact spectrocolorimeter. To compare models across the range by sample type and automation needs, visit the non-contact spectrocolorimeter category.
What to Confirm Before Implementing the YL4520
First identify whether samples are liquids, pastes, powders, granules or other materials. Then review surface uniformity, container or fixture design, fixed measuring distance, measurement location, ambient-light control, calibration procedure and internal color-difference acceptance limits. For an automated installation, also account for production speed, equipment layout and available space. Representative sample trials can help determine whether the measurement method fits the process.
YL4520 Frequently Asked Questions
These answers cover common questions about non-contact measurement, special sample types and color quality-control implementation. Confirm application suitability with actual samples and conditions.
What types of samples can the YL4520 measure?
The YL4520 can be evaluated for liquids, pastes, powders and other samples that are inconvenient to measure by direct contact. It may also suit color-analysis workflows where avoiding direct contact between the probe and sample is preferred. Sample condition, container and measurement setup affect suitability.
What optical geometry does the YL4520 use?
It uses 45° annular uniform illumination and 0° reception, forming a 45°/0° optical geometry. This setup can be used to collect sample-surface color data and compare color differences under defined conditions.
What are the potential benefits of non-contact measurement?
The probe does not need to touch the sample. This may reduce probe residue, cross-contamination and surface disturbance when measuring liquids, pastes, powders or other special samples. Results depend on the sample and the measurement procedure.
Can the YL4520 be used in a laboratory?
It can be evaluated for R&D color matching, sample color-data development, batch comparison and color-standard management in laboratories and R&D workflows that need non-contact measurement.
Can the YL4520 be integrated into an automated production line?
It may be evaluated for automated color measurement and quality control when the equipment and measurement conditions are suitable. Confirm fixed distance, sample position, line speed, installation space, communications and the site's quality-control process before integration.
What should be considered for liquid samples?
Keep the container, liquid level, bubbles, surface condition and measurement location consistent. If the sample flows or settles, define a repeatable timing and handling procedure for each measurement.
Can the YL4520 measure powder samples?
Powder measurement can be evaluated. Consider fill height, surface flatness, particle distribution and sampling procedure so that differences in sample presentation do not dominate comparisons between measurements.
How should I choose between the YL4520 and a contact spectrocolorimeter?
Consider a non-contact instrument such as the YL4520 when the sample is a liquid, paste or powder, or when direct probe contact is unsuitable. If the sample has a flat surface and can be contacted consistently, and the main need is routine laboratory or incoming-material color-difference control, compare it with a standard spectrocolorimeter.
What information should I provide before implementation?
Provide the material and sample form, surface condition, container or sample dimensions, planned measurement method, automation requirements, current quality standard and acceptance range. These details help assess a suitable measurement configuration.
