产品系列说明

• 适用于光谱学、比色法、辐射线测定和机器视觉应用
• 漫反射与视角无关
• 耐用、稳定、可清洗
• 提供具有 NIST 可追踪校准证书和数据的序列化版本

The Spectralon® 白色、灰度和彩色漫反射标准板可展示接近完美的朗伯表面，由此具有极高的一致性、可重复，且与视角无关。它们可用作各种行业、实验室和现场应用（例如透射/反射/吸收光谱学、传感器线性特征、比色法、辐射线测定和机器视觉应用）的参考标准板，尤其适用于校准色度计、分光计、分光光度计、反射计、比重计、积分球系统、相机和成像系统、遥感系统、接近度传感器及其他光学或摄影设备。

白色与灰度标准板的明视区域平坦度可达到惊人的 ±1%，在 250 至 2500nm 的整个波长范围内保持在 ±4%。彩色标准板可用于照明和色彩复制应用（例如显示屏、纺织品、墨水和油漆制造），并且随温度的变化展示出极为平缓的色移，可轻松进行量化与纠正。运用可选 NIST 可追踪校准证书和数据，漫反射标准板可转化为绝对标准板（采用间隔为 50nm 的经认证可追踪数据报告）。白色与灰度标准板在 250 至 2500nm 的波长范围内进行校准，而彩色标准板的校准范围是 350 至 850nm，并随附以三色刺激值、色度坐标、UCS 坐标、CIELAB 颜色空间坐标和 CIELUV 颜色空间坐标表示的其他数据。

所有漫反射标准板都具有耐用性、热稳定性和化学稳定性，并且可清洗。即使暴露在恶劣环境中，它们也会保持均匀性和完整性。所有标准板都存放在具有护盖的耐用聚甲醛树脂外壳中，套件包括配备软垫并具有 8 个存放槽的专用优质木箱。

The White (99%) Standards are spectrally flat to ±1% over the photopic region and maintain ±4% for the entire wavelength region of 250 to 2500nm. The Grayscale Standards have their respective nominal reflectance values. The Color Standards can be used for lighting and color reproduction applications such as display, textile, ink, and paint manufacturing, and they exhibit extremely gradual color shift with changing temperature that can be easily quantified and corrected. With the optional NIST Traceable Calibration Certificate and Data, the Diffuse Reflectance Standards transform into absolute standards with certified traceable data. The calibration certificate reports data in 50nm intervals, while data file included in the USB thumb drive reports in as fine as 1nm intervals. The White and Grayscale Standards are calibrated from 250 to 2500nm wavelengths, while the Color Standards are calibrated from 350 to 850nm and come with additional data in tristimulus values, chromaticity coordinates, UCS coordinates, CIELAB color space coordinates, and CIELUV color space coordinates.

All diffuse reflectance standards are durable, thermally and chemically stable, and washable. They retain uniformity and integrity despite exposure to harsh environments. All standards come mounted in a durable Delrin housing with a protective cover, while the sets include a dedicated premium wooden storage case with soft padding offering 8 storage slots.
