A light guide plate and a protein blot analyzer

Abstract

This utility model relates to a protein blot detection technology, specifically a light guide plate and a protein blot analyzer. One type of light guide plate, used for protein blot detection, includes: a base light source plate, which outputs at least two optical signals in a predetermined sequence under the action of a control command; a first attenuation layer, disposed in the light output direction of the base light source plate, for attenuating the optical signals before outputting them; and a homogenizing layer, disposed in the light output direction of the attenuation layer, for homogenizing the attenuated optical signals to form a uniform projected light signal output.
