UV Viewing Cabinet

The UV Viewing Cabinet is a precision instrument designed to detect and analyze fluorescent substances in a wide range of materials. By providing controlled ultraviolet (UV) and visible light exposure, it allows accurate observation, comparison, and documentation of fluorescence for quality control, impurity detection, and material authentication.

Application

(1) Coatings and paints: Detect and analyze phosphors in plastics, paints, and coatings.

(2) Aluminum foil: Examine fluorescent substances in aluminum foil and related materials.

(3) Paper: Test for fluorescent substances in various types of paper.

(4) Plastics: Detect fluorescence in plastics and other polymer materials.

(5) Quality control: Evaluate material uniformity and detect impurities.

(6) Research and development: Study fluorescent behavior of new compounds or coatings.

(7) Non-destructive testing: Examine samples without damaging or altering them.

Standards

(1) GB/T 16422.3 – Fluorescent inspection methods for non-metallic materials.

(2) GB/T 14522 – Material fluorescence testing standards.

(3) ASTM G154 – Standard practice for fluorescent testing of non-metallic materials.

(4) ISO 4892-3 – Plastics exposure to laboratory light sources for fluorescence testing.

(5) SAE J2020 – Automotive exterior parts fluorescence inspection.

Features

(1) Integrated UV light sources at 254 nm (short-wave) and 365 nm (long-wave) for excitation of different fluorescent compounds.

(2) D65 standard visible light source for comparison under controlled white light conditions.

(3) Camera system for capturing and documenting sample fluorescence images.

(4) Light-tight chamber for controlled environment and operator protection.

(5) UV filter (200×50 mm) to regulate emitted UV light.

(6) Host unit for centralized control and image analysis.

(7) Picture comparison function for side-by-side observation of samples under UV or visible light.

(8) Non-destructive testing, supporting quality control, impurity detection, and material authentication.

Test Procedures

(1) Place the sample inside the UV Viewing Cabinet.

(2) Select the UV wavelength (254 nm or 365 nm) or the visible light source (D65) as required.

(3) Activate the light source and allow the sample to be illuminated under controlled conditions.

(4) Observe the fluorescence visually or capture images using the integrated camera system.

(5) Use the picture comparison function to analyze differences between samples or compare with reference standards.

(6) Record and document the observations for quality control or R&D purposes.

Maintenance Information

(1) Keep the chamber clean and free from dust or residues that may affect UV exposure.

(2) Inspect UV lamps and filters periodically for damage or reduced output.

(3) Handle the camera system carefully and avoid exposure to excessive UV light.

(4) Ensure all electrical connections are secure and the power supply is stable.

(5) Avoid direct eye exposure to UV light during operation.

(6) Follow manufacturer guidelines for servicing and lamp replacement.
