OPTOREADER – Optical detection for microfluidics

Optical Reader for Microfluidics: the OptoReader brings about the strength of duplex optical fiber measurement, high optical sensitivity and real-time processing capacity within a compact design. It offers the same performance as a microscope while being more cost effective. The use of optical fiber for both illumination and light collection largely frees up the space around the experiment and reduces the optical alignment to only one step.
