Diatoms at low magnification

Second to last diatom; imaged with a 1.4 NA oil objective and a 1.4 NA oil condenser; this image was not made in class but by the instructor; the striations occur at a periodicity of approximately 300 nm, right at the limit of resolution of the light microscope

Image made in class of another diatom

Image made in lab of a diatom with striations at intervals of approximately 500 nm; oil immersion 1.3 NA objective
