Light plays a pivotal role in influencing the growth processes of plant samples. Depending on the method of tissue cultivation, the type of plant specimen, and its growth stage, varying levels of illumination are required to ensure adequate photosynthesis.

Our approach involves collaborating with leading experts in biology and spectroscopy. We focus on researching the growth characteristics of plants; developing light sources with a spectrum appropriate to the plants' sensitivity; integrating advanced technology in the production of high-efficiency, energy-saving lighting sources; and designing lighting equipment that ensures optimal illumination for in vitro cultivation.
