The Sunglasses Transmittance Tester LTRP-F11 is designed with optional test interfaces that support a variety of eyewear, including single lenses, contact lenses, and finished sunglasses. It uses magnetic brackets that securely position the lenses for proper alignment and measurement accuracy. During testing, the device detects parameters such as lens center position, shape, and optical density, while also analyzing color distortion and visual comfort. The tester automatically calculates and records critical performance metrics like UV absorption, optical uniformity, and compliance indicators.
The Sunglasses Transmittance Tester LTRP-F11 covers a spectral range from 360 nm to 980 nm, making it suitable for analyzing both ultraviolet (UV) and visible (VIS) light regions. Its wide spectral range also supports specialized evaluations such as blue light and driving lens performance tests.
Our Sunglasses Transmittance Tester LTRP-F11 complies with a broad range of international and regional standards, including ISO, GB, QB, EN, ANSI, CSA, and AS/NZS. It supports testing for optical lenses, sunglasses, driving glasses, protective glasses, and contact lenses according to specific country-based protocols. Standards such as ISO 8980-3:2003, EN ISO 12312-1:2013, ANSI Z80.3-2018, and AS/NZS 1067.1:2016 are integrated into the system. This ensures that the tester meets safety and optical quality requirements across global markets.
The Sunglasses Transmittance Tester LTRP-F11 performs precise wide-spectrum transmittance testing that covers VIS, ranging from 360 nm to 780 nm. It calculates transmittance, Q factor, UV integral value, TV integral value, and CIE color space, all within a single test cycle. Its 5 mm light spot and ±0.5% transmittance accuracy guarantee high-resolution data output. The tester meets the fine spectral resolution requirement of 1 nm, enabling accurate and repeatable results.
The Sunglasses Transmittance Tester LTRP-F11 offers a full-band test within the test area, enabling comprehensive optical evaluation of sunglass lenses. It provides a wide range of test parameters, including TV integral value, UV integral value, Q factor, CIE color limits, and Lab color space metrics. These parameters ensure conformity with international standards and allow precise assessment of lens clarity, protection level, and color accuracy.
