In food safety testing, the detection of microbial contamination and parasite eggs mainly relies on brightfield microscopy. Food contains a wide variety of microorganisms with small sizes and variable quantities, which imposes high requirements on the resolution of microscopic imaging.
Parasite eggs are tiny and often mixed with other components in food, requiring microscopes to clearly distinguish subtle structural differences. Especially in meat samples, high contrast and image clarity are essential.
Finally, for illegal additive screening, low-concentration samples typically depend on fluorescence microscopy. This demands microscopes to have excellent fluorescence imaging performance to accurately identify and locate tiny dye particles.
