The 410-Solar provides total, specular and diffuse reflectance. The 410-Solar-i has a larger beam size which increases accuracy for non-uniform surfaces. It has faster measurements, and only requires calibration with one coupon but is limited to providing total solar reflectance without the breakdown of specular and diffuse percentage.
