The SF650X Reflectance/Transmittance Spectrophotometer was designed for superior transmittance and haze measurements, yet it is capable of handling measurements in the reflectance mode as well. The unit delivers transmission measurements for all sample types, including regular transmittance of transparent solid and liquid samples; total and diffuse transmittance of translucent samples (i.e., those samples that are neither completely transparent nor totally opaque); and haze measurements for those slightly cloudy samples that scatter little light. The unit also handles the sequential reflectance and total-transmittance measurements required by some color-matching applications.
