CHN SPEC CS-730 Visible & Infrared Spectrum Haze Meter (0/d, 400–1100 nm)

CHN SPEC CS-730 Visible & Infrared Spectrum Haze Meter (0/d, 400–1100 nm)

The CHN SPEC CS-730 Visible & Infrared Spectrum Haze Meter is the most advanced optical measurement device in the transmittance testing segment. The exclusive power of the CS-730 lies in the combination of a 0/d optical system and an ultra-wide spectral scanning capability from 400nm to 1100nm. This device not only analyzes color and haze in the visible light range but also accurately evaluates the penetration level of infrared rays, meeting the strict R&D requirements of high-tech industries.

Outstanding Features

• Ultra-wide wavelength range (400 – 1100 nm): Completely different from standard meters (which only measure from 400-700 nm), the CS-730 is equipped with a sensor capable of continuously scanning the visible light spectrum (Visible) and near-infrared spectrum (NIR – Near Infrared) up to 1100 nm. This helps the device accurately analyze the transmittance rate of invisible infrared rays.
• Specialized 0/d optical system: The device uses an illumination structure at a 0-degree angle (direct illumination) and receives diffused light (0/d) through an integrating sphere. This design optimizes the ability to capture all scattered light rays passing through the sample, providing Haze and Transmittance measurement results with absolute accuracy.
• “All-in-one” optical measurement: The CS-730 is a combination of a Haze meter, colorimeter, and infrared spectrophotometer. With just one operation, the device provides full data: Haze, Total Transmittance, Transmittance at specific wavelengths (especially 850nm, 940nm used in IR sensors), and Lab*, LCh, YI, WI color systems.
• Versatile sample measurement chamber: The flexible benchtop measurement chamber design allows the device to perfectly handle multiple material formats: from solid samples (tempered glass, plastic films) to liquid samples (via cuvettes) for measuring various solutions and chemicals.
• Meeting strict international standards: The device operates stably and complies with the highest standards of the optical industry such as ASTM D1003, ISO 13468, ISO 14782, CIE 15, etc.

Practical Applications

With the capability to analyze both visible light and infrared rays, the CHN SPEC CS-730 is a must-have device in the R&D labs of:

• Optoelectronic Components & Smart Devices: Inspecting the infrared transmittance of IR sensor windows, infrared camera lenses, and LiDAR sensor covers on autonomous vehicles and smartphones (often requiring good transmittance at 850nm or 940nm wavelengths).
• National Security & Surveillance Cameras: Evaluating the quality of night vision lens materials and infrared filters (IR filters).
• Automotive Glass & Window Tint Film Manufacturing: Testing the thermal insulation (IR blocking) capability of Low-E insulated glass and tint films, while ensuring transparency does not blur the driver’s vision.
• Specialized Plastics and Chemicals: Analyzing the haze, yellowness, and infrared absorption properties of thin-film polymer materials and optical solvents.
