The Allevi Light Meter is a light meter that has a probe specifically designed to measure either 365nm or 405nm wavelengths. The Allevi Light Meter is a useful tool to determine the specific power in mW/cm2 that the light source of your bioprinter outputs before beginning your bioprinting experiments. While it is not necessary to measure the light intensity between every print, we recommend using the Allevi Light Meter to check the power output of your light source at the start of each print session to ensure performance and consistency of crosslinking power between print experiments.
