Objective
OBL-20-A
These objectives are educational microscope objectives. They are to the JIS standard (Japanese Industry Standard), have Short focal length, high NA and are fit for beam divergent use.
◦Full color correction throughout the visible wavelength.
◦The OBL-40 and OBL-60 have a built-in spring in the tip of the objective lens.
◦These objective lenses are finite.
◦To mount it to a microscope, a finite 160mm adaptor is required.
◦The distance from the attachment face of the objective lens to the image is 150mm.
