IdealPhotonics' customizable optogenetic kit is a systematic combination of modular optical and electronic components (such as LED/laser sources, fiber optic probes, and stimulation controllers). By flexibly configuring wavelengths (e.g., 470nm/590nm), light intensity, and timing parameters, it enables precise manipulation of photostimulation (e.g., neuronal activation/inhibition) in living or ex vivo samples, providing targeted experimental solutions for neuroscience research.It features multi-band tunability (covering UV-NIR), μW-mW level power control, and millisecond-level timing accuracy. It also boasts biocompatibility (sterile/temperature-controlled) and open-source software support (e.g., Python/Matlab API), meeting the needs of the entire chain from in vitro culture to in vivo experiments.
