Core Advantages

1. Transient UV Spectrum Acquisition: Full-Band Scan in 1 Second

   Advanced 500KHz high-speed spectral acquisition technology fundamentally revolutionizes the slow point-by-point scanning mechanism. Detector arrays enable nanosecond-level synchronous response, completing full-band data collection from UVA to UVB (280–500nm) within 0.1ms integration time. Parallel computing supports the entire workflow—from data capture and signal averaging to SPF result analysis—completed in just 1 second.

   Outstanding SNR: Ultra-fast acquisition enables thousands of real-time averages in a very short time, easily achieving SNR > 1000:1, ensuring fast and accurate SPF evaluation.

2. Intelligent Integrated Control System with Built-In Touchscreen

   Equipped with a high-performance quad-core industrial processor and an optimized embedded OS, eliminating dependence on external PCs. All operations are performed via an industrial-grade capacitive touchscreen following SOP-driven logic, reducing the learning curve and minimizing errors. From spectrum acquisition and dark current correction to SPF value and UVA/UVB transmittance calculations, a single button initiates automated sequences for seamless“sample-to-result"processing.

3. High Dynamic Range Photodetection: SPF Measurement up to 2000

   Equipped with a research-grade high dynamic range photodetector array, it achieves an ultra-wide dynamic range of 50,000:1, ensuring precise capture of signals from high light transmittance to sunscreen. The quantum efficiency in the ultraviolet band is close to 90%, making signal response more sensitive. Advanced cooling technology suppresses dark noise to an ultra-low level of <0.1 mv/rms, allowing clear signal acquisition even with millisecond-level exposures. It easily handles extreme challenges with ultra-low transmittance below 0.05%, with a detection sensitivity of up to SPF 2000.

4. Ultra-Wide UV Coverage: Comprehensive UVA/UVB Evaluation

   Adopting a symmetrical optical path design and research-grade back-illuminated area array detectors, it achieves an ultra-wide ultraviolet spectral measurement range from 280nm to 500nm. This not only fully covers the UVB (280–315nm) and UVA (315–400nm) bands defined by international standards, but also extends the measurement range into the UVA-I long-wave region up to 500nm, ensuring the capture of even the finest spectral details.

   Exceeding Standard Requirements: It far exceeds the 400 nm upper limit specified in standards such as ISO 24443, ISO 23675, FDA 2012 & 2019, providing decisive data support for the evaluation of cutting-edge sunscreen products.

   High-Resolution Analysis: With an optical resolution of 2 nm, it can accurately resolve every detail of the spectrum, enabling a more comprehensive and precise evaluation of the true broad-spectrum UV protection efficacy of cosmetic products. This ensures your test results maintain undisputed integrity and authority in all applications.

5. Global Standards Compatibility: Built-In Authoritative Testing Methods

   Preloaded with multiple authoritative standards, including the Cosmetic Safety Technical Specification, ISO 23675 cosmetic sunscreen testing standard, and ISO 24443 UVA protection efficacy determination method. The system instantly locks all key parameters of the selected standard—specific wavelength range, data interval, and SPF calculation weighting—ensuring that every test complies with the requirements of the target regulations.

   Structured Update Support: With a modular software architecture, when international standards are updated or new versions are released, you can quickly gain compatibility with the latest standards through a simple software upgrade package. This ensures long-term effectiveness of your investment and keeps you aligned with the international forefront at all times.
