 # Open-JIP
-Open-JIP is an open-source chlorophyll fluorometer used for quantifying photosynthetic processes is terrestrial plants and microalgae. The original device was published in [Photosynthesis Research](https://doi.org/10.1007/s11120-019-00673-2) in 2019. Since then a number of upgrades have been made to improve the performace of the device.

You can use 3D modeling software to do this such as [Fusion360](https://www.autodesk.com/products/fusion-360/overview) or [Solidworks](https://www.solidworks.com/).
