Haze and light transmittance are important optical properties for transparent and translucent materials, including films, sheets, glass, andpackaging. The right instrument depends on the material, the test method, and the decision you need to make from the result.
5 factors to confirm before buying
- Sample type and size. Check whether you will test plastic film, rigid sheets, glass, or finished components. Confirm sample dimensions andwhether curved or textured samples are involved.
- Measurement parameters. Confirm whether you need haze, total luminous transmittance, or both. Do not assume every instrumentmeasures every parameter.
- Applicable test method or standard. Ask your customer or laboratory which method is required and confirm that the instrument supportsit.
- Measurement aperture and sample handling. The measurement area should fit the sample and provide representative results. Considerfixtures or repeatable positioning for small samples.
- Repeatability, calibration, and data output. Review required repeatability, verification procedures, report format, and whether data mustbe exported to a PC or quality system.
Typical applications
• Transparent plastic films and sheets
• Glass and glazing materials
• Packaging and optical material QC
• Incoming inspection andproduction consistency checksSelection tip: If your customer specifies a standard or acceptance limit, start with that requirement—not the instrument price.
