Finite Objectives
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-A 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.
