This is a 40X plan fluor (semi-apochromatic) objective lens with a high 0.75 NA. Designed for infinity-corrected microscopes with RMS thread, this lens has improved color-correction and resolution compared to achromatic lenses. With its improved optics, this lens is ideally suited for fluorescence microscopy and photomicrography. It has a spring nosecone to prevent damage to the lens or specimen.
