A biochip reader, superior in signal to noise ratios and economical in costs, comprising a light source, a lens for collimating light emitted by the light source, an optical detector for detecting fluorescent light produced by the excitation light at samples, and an objective lens for condensing fluorescent light produced at a biochip where samples are deposited, wherein the excitation light is projected onto the substrate of the biochip at a critical angle or greater.
