Product Introduction

The TH-110 Haze Meter is a precision optical instrument designed to measure haze and total luminous transmittance of transparent and translucent materials, including glass, plastic sheet, film, packaging, display screens, and protective covers. It is built to give quality control and R&D teams a fast, repeatable, and standards-compliant way to evaluate optical clarity during production, incoming inspection, and product development.

Total luminous transmittance is the ratio of the total amount of light that passes through a sample to the amount of light that was originally incident on it, expressed as a percentage. A higher transmittance value means more light passes through the material, which generally corresponds to a brighter, clearer appearance. Transmittance is affected by surface reflection, absorption within the material, and scattering caused by internal defects or surface texture.

Haze refers to the percentage of transmitted light that is scattered from the incident beam by more than a specified angle, giving the material a cloudy, milky, or hazy appearance rather than a perfectly clear one. Haze is typically caused by surface roughness, embedded particles, crystallinity in plastics, or micro-scratches. Even a material with high total transmittance can have a high haze value if a large proportion of the transmitted light is scattered rather than passing straight through — this is why haze and transmittance are usually reported together rather than in isolation.

For manufacturers of glass, film, packaging, optical components, and display covers, haze and transmittance directly affect how a product looks and performs. Excessive haze can make a touchscreen appear dull, a protective film look cloudy, or a food package appear less attractive on the shelf. Consistent, standards-compliant measurement allows manufacturers to catch these defects early, maintain consistent quality between production batches, and provide objective data to customers and regulators.

Technical Parameters

The table below summarizes the complete technical specifications of the TH-110 Haze Meter. All values are as specified by the manufacturer and must not be altered.

Haze Meter Application

The TS-100 is used across a broad range of transparent and translucent materials where optical clarity is a key quality parameter. Representative application areas include:

Mobile Device Cover

Tempered glass and cover lenses for smartphones and tablets must maintain high transmittance and low haze so that the display beneath remains bright, sharp and free of visible cloudiness. Haze testing during manufacturing helps ensure cover glass batches meet the clarity level expected by device brands.

Phone Film

Screen protection films are applied directly over the display, so any haze in the film is immediately visible to the end user as blurriness or a milky appearance. Manufacturers use haze and transmittance testing to grade film quality and to distinguish standard films from premium, high-clarity variants.

Plastic Film

Plastic films used in packaging, agriculture, optical products and industrial applications are tested for haze and transmittance to confirm they meet the optical clarity or light-diffusion properties specified by the customer, and to detect processing defects such as uneven stretching, contamination or surface scratching.

Glasses

Eyewear lenses, including prescription lenses, sunglasses and safety glasses, are tested for haze to confirm that the lens does not distort or scatter light in a way that would impair the wearer's vision, and to verify compliance with relevant optical quality standards.

In each of these applications, haze and transmittance measurements help manufacturers verify that materials meet optical clarity requirements, monitor consistency between production batches, and confirm compliance with the relevant ASTM/ISO/JIS/GB standards referenced in the Technical Data table above.
