LISUN can provide very fine Photo Detectors. They are NIM traceable (directly compared with NIM standard head) and is validated to PTB of Germany.
Problem of the part filtering technology: the tested light on the photo detector must be strictly uniform, otherwise even for a so called f1’=0.5% photo detector, its actual f1’ may exceed 10%.
Full-filtering technology: in order to achieve a high-performance photometer head, the filters should be specially designed, and the thickness error should be strictly limited within 1μm.
