These Laser Line Generator Lenses, also known as Powell lenses, generate a straight, uniform laser line by fanning out a collimated beam in one dimension, as shown in the diagram above. The apex of each lens features an aspheric curve that evenly distributes the optical power, resulting in an intensity variation of less than 25% over the center portion of the line. You will get more even energy distribution along the laser line than using the rod lenses and lenses.
This kit is used for the qualitative determination of COVID-19 IgM/IgG antibodies in human serum, plasma and venous whole blood samples in vitro. as an auxiliary diagnosis of COVID-19 infection.
[Detection principle]

Unbound rabbit IgG colloidal gold bond chromatography to quality control line (C) combined with precoated sheep anti-rabbit IgG antibody presented a red precipitation line.
If the samples do not contain COVID-19 IgG antibody and/or COVID-19 IgM antibody, there is no corresponding red precipitation line existed in the test area. A red precipitation line appears on the quality control line (C) no matter if there is COVID-19 IgG antibody and/or COVID-19 IgM antibody in the sample or not.
