Pike 10 Spec – Specular Reflectance

The PIKE Technologies 10Spec is an optimized specular reflectance accessory designed to make high performance measurements of sample reflectivity. 



Pike Technologies 10Spec Specular Reflectance Accessory

The 10Spec produces a collimated beam to illuminate the sample area such that the reflectivity measurement is uniformly 10 degrees and not an average of angles produced by a focused beam accessory design. The 10Spec specular reflectance accessory is recommended to measure the reflectivity of glass per ASTM Standard E1585-93. The 10Spec may also be used to measure near-normal reflectivity of a wide variety of surfaces including military devices, reflecting optics, anti-reflective (AR) coated surfaces, and other reflecting and non-reflecting materials.
