Specialized fluorescent semi complex extinction objective lens:
A large number of crystal optical materials are used in infinite flat field semi complex fluorescence objective lenses; Correction of various chromatic aberration and design of ultra large numerical aperture; Provide high-definition and high contrast microscopic images within the full field of view; During fluorescence observation The image is bright and clear, with a pure black background and outstanding performance in UV fluorescence.
The excellent aberration correction performance of the new generation of infinite far-field half complex achromatic professional fluorescent objective lenses is as high as the numerical aperture of ordinary flat field objectives25%, making the image brightness stronger and the image resolution higher. Using high-quality and environmentally friendly optical materials. The application of advanced multi-layer broadband coating technology has significant advantages in the width of the wavelength band and the transmittance of ultraviolet light, making it the best choice for professional fluorescence observation of various types of cells and pathological sections.
