Introduction:
In photocatalytic (photochemical) studies, researchers often want to observe photocatalytic reactions in the narrow spectral wavelength range. The conventional monochromator is designed to focus on monochromatic light as a signal source or a weak excitation source, and the output parameters are more biased toward higher monochromaticity and higher stray light suppression, but often because the output energy is too low. It cannot be applied in the field of photocatalysis.
The wavelength continuously adjustable output light source PLS-AL150300, the principle is to increase the output/input energy ratio by increasing the width of the entrance slit, and the monochromatic light intensity can be increased from 200 to 400 microwatts to several tens of times. Milliwatt level, can meet the measurement of photocatalysis, IPCE and so on. Features:
1. Adopt unique optical component design, with higher monochromaticity and higher stray light suppression;
2. It can be equipped with electric filter wheel, which is easy to operate and convenient.
3. The wavelength scanning range is larger, which can meet the needs of photoelectrochemistry and solar cell research in a wide wavelength range.
