通过对单一来源的材料进行多中心测量，并在一台仪器上对该材料的各种制剂进行了比较，证明了40g/L氧化Ho-10%(体积分数)高氯酸溶液的18个吸收带的透过率最小值是本征可溯源波长标准。用于化学分光光度计波长标度的实验校准或验证的适合用途的人工制品标准可以由最终用户自己或商业标准生产者仔细地生产。固有的(数据)标准赋予了SI长度单位的可追溯性，而不是昂贵的传输伪影和重复的校准过程。对于0.1 nm间隔的0.1-3.0 nm的仪器光谱带宽提供了认证值，并且以更宽的间隔向10 nm的光谱带宽提供了信息值。对于经过认证的频段位置，扩展不确定度通常小于±0.1 nm。
The transmittance minima of 18 absorption bands of a solution of 40 g/L holmium oxide in 10% (volume fraction) perchloric acid are certified as intrinsic traceable wavelength standards, by means of a multicenter measurement on material from a single source coupled with comparisons of a variety of preparations of the material evaluated on a single instrument. Fit-for-purpose artifact standards for the experimental calibration or validation of wavelength scales of chemical spectrophotometers can be carefully produced by end users themselves or by commercial standards producers. The intrinsic (data) standard confers traceability to the SI unit of length in place of costly transfer artifacts and repetitive calibration procedures. Certified values are provided for instrumental spectral bandwidths of 0.1–3.0 nm in 0.1 nm intervals, and information values are provided to a spectral bandwidth of 10 nm at wider intervals. Expanded uncertainties are typically less than ±0.1 nm for certified band positions.
