Core Advantages

1. Transient Ultraviolet Spectral Acquisition Technology: Full-Spectrum Scan in 1 Second

The system adopts advanced 500 kHz high-speed spectral acquisition technology, fundamentally replacing the slow point-by-point scanning mechanism used in traditional instruments.

The detector array enables nanosecond-level synchronous response, allowing full-spectrum data acquisition from UVA to UVB (280–500 nm) within an extremely short 0.1 ms integration time.

With powerful parallel computing capability, the entire process—from data acquisition and signal averaging to SPF result analysis—can be completed within 1 second, significantly improving testing efficiency.

Excellent Signal-to-Noise Ratio

Ultra-high-speed acquisition allows thousands of measurements to be performed and averaged in real time within a very short period, easily achieving a signal-to-noise ratio (SNR) greater than 1000:1.

This provides high-quality spectral data and ensures fast and accurate SPF evaluation.

Intelligent Integrated Control System with Built-in HD Touchscreen for Standalone Instant Analysis

The system is equipped with a high-performance quad-core industrial processor and an embedded operating system optimized for instrument control. It eliminates dependence on an external PC, fundamentally ensuring system stability and real-time data processing capability.

All operations are performed through an industrial-grade capacitive touchscreen. The interface follows SOP-driven operational logic, significantly reducing the learning curve and preventing operational errors.

From spectral data acquisition and dark current correction to SPF value calculation and UVA/UVB transmittance analysis based on complex standards, a single touch triggers the preset automated testing sequence. This enables a seamless workflow from “sample loading” to “result output.”

3. High Dynamic Range Photoelectric Detection System: SPF Measurement up to 2000

The instrument is equipped with a research-grade high dynamic range photoelectric detector array, achieving an ultra-wide dynamic range of 50.000:1. ensuring accurate signal capture from high-transmittance samples to highly opaque sunscreen formulations.

The detector provides quantum efficiency close to 90% in the ultraviolet range, delivering higher sensitivity and improved signal response. Through advanced cooling technology, dark noise is suppressed to an ultra-low level of <0.1 mV RMS, allowing clear signal acquisition even under millisecond-level exposure times.

The system can easily measure extremely low transmittance levels below 0.05%, enabling detection sensitivity up to SPF 2000.

4. Ultra-Wide Spectrum UV Coverage Technology: Accurate Evaluation of Full UVA/UVB Protection

The instrument adopts a symmetrical optical path design combined with a research-grade back-illuminated area detector, enabling an ultra-wide ultraviolet spectral measurement range from 280 nm to 500 nm.

This range fully covers the internationally defined UVB (280–315 nm) and UVA (315–400 nm) regions, while further extending into the long-wave UVA-I region up to 500 nm, ensuring that even the most subtle spectral information can be accurately captured.

Beyond Standard Requirements: The measurement range significantly exceeds the 400 nm upper limit specified in standards such as ISO 24443. ISO 23675. and FDA 2012 & 2019. providing decisive data support for evaluating advanced sunscreen formulations.

High-Resolution Spectral Analysis: With an optical resolution of 2 nm, the system precisely resolves fine spectral details, enabling more comprehensive and accurate evaluation of the real ultraviolet protection performance of cosmetic products across the full spectrum. This ensures that test results remain complete, reliable, and authoritative in any professional application scenario.

5. Global Standard Compatibility: Built-in International Authoritative Test Methods

The system integrates multiple internationally recognized testing standards, including the Cosmetic Safety Technical Specification, ISO 23675 (Cosmetics — Sunscreen Test Methods), and ISO 24443 (Determination of UVA Protection Efficacy).

The instrument automatically locks all critical parameters required by the selected standard, including specific wavelength ranges, data step intervals, and SPF calculation weighting factors, ensuring that every test complies with the requirements of the applicable regulatory framework.

Modular Upgrade Support:

The software adopts a modular architecture, allowing rapid compatibility with updated or newly released international standards through simple software upgrade packages. This ensures long-term usability of the system and keeps the instrument aligned with the latest global regulatry and technical developments
