Spectral transmittance measurement kit 
EXW Price:


Reflection and transmission are the basic optical properties of an item, and also the basic content of spectral measurement. For different types of samples, in order to obtain the best spectral measurement data, the two basic modes of reflection and transmission will evolve into more forms. There are mainly two kinds of reflections on the surface of the object: mirror reflection and diffuse reflection. The reflection of light on a perfectly flat surface is mirror. The reflection of light on a rough surface is diffuse. The reflection of light on thesurface of most objects is somewhere in between. Reflectance measurement can be used to measure the reflectivity of components, measure the reflected color of objects and the composition information in chemical samples.


• Easy operation, good repeatability and fast detection
• Transmittance value can be read in real time, data can be repeatedly imported, read and used

• Adjustable optical path

• Automatic reading of peak wavelength, center wavelength, FWHM and transmittance values


• Suitable for the measurement of solids with smooth surfaces such as filters
