What is the device used to measure percent light absorption in pigments?

I remember finding the percent light absorption in the pigments of some vegetables for a high school bio lab. I am pretty sure the device used was not specific for pigments. The device was user friendly- we just stuck some tubes in a magical box and the box displayed a number.
