Sample collection component and manufacturing method thereof

A sample collection component, comprising:

• a main body having a sample storing space which is sealable and allows a light to pass through;
• and
• a removable light shielding component disposed on the main body and located outside the sample storing space for shielding at least a portion of the light that passes through the sample storing space,
• wherein the main body comprises:
• a first substrate having a first surface and a second surface opposite to each other;
• a second substrate having a third surface and a fourth surface opposite to each other, wherein the first substrate and the second substrate are stacked on each other and the second surface faces the third surface;
• a spacer disposed directly between the second surface and the third surface and connecting and fixing the first substrate and the second substrate to form the sample storing space between the first substrate and the second substrate;
• a first film located on the second surface of the first substrate;
• a second film located on the third surface of the second substrate, wherein the first film, the second film, and the spacer together surround the sample storing space;
• a first groove formed on the second surface of the first substrate, where at least a portion of the first film is deposited on an internal surface of the first groove;
• and
• a second groove formed on the third surface of the second substrate, where at least a corresponding portion of the second film is deposited on a corresponding internal surface of the second groove,
• wherein a thickness of the first groove is smaller than a thickness of the first substrate, and a thickness of the second groove is smaller than a thickness of the second substrate.
