Diffuse/Specular Reflectance Accessory
Diffuse/Specular reflectance accessory is a versatile diffuse reflectance and specular reflectance accessory. Diffuse reflection mode is used for transparent and powder sample analysis. Specular reflection mode is for measuring smooth reflective surface and coating surface.
• High light throughput
• Small light spot, able to measure micro samples
• Easy operation, no internal adjustment needed • Variable angle of incidence
• Optical aberration compensation
• Fast change of powder cup
Specular Reflection Accessory
Specular reflection accessory is fixed 10-degree angle of incidence. At a near-normal angle, the polarization effects on reflectivity are minimized. Specular reflection accessory is recommended to measure the reflectivity of glass. However, it 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.
• Fixed 10-degree angle of incidence
