An optical detection device is provided. The detection device includes a light source emitting light rays, a focusing lens, and a sample testing member. The focusing lens refracts the light rays emitting from the light source to a pre-defined area on the sample testing member and focuses light rays diffusely reflected by the sample testing member. The detection device further includes an aperture diaphragm having an aperture. The aperture is configured to allow the focused reflected light rays to pass through. The detection device further includes a photodetector configured to receive the focused reflected rays passing through the aperture.
