Lens Apo Meaning. What does the word 'apo' on a lens really mean? Compared with a standard lens of identical speed and focal length, an apochromatic (apo) lens displays considerably better image. The term 'apochromat' gets used in various ways, and now it means various things. A leica apo lens has to be 'apo' across a much wider area. In normal lens designs, blue and green light converges on one focal plane, while the (longer) wavelength of red light is refracted to a slightly different plane of. A fundamental problem with camera optics is that the light that forms the image on the film or sensor comprises a range of wavelengths. Years ago, it just meant. Therefore, there are only four leica lenses that carry the apo designation: The 50mm f2 summicron apo is also an aspherical lens design. You may see apo on your lens. [1] the residual color error (secondary spectrum) can be up. Apo = apochromatic and asph = aspherical. And to confuse this i think. An apo or apochromatic lens is usually an anonymous design feature. Apochromatic lenses are designed to bring three wavelengths (typically red, green, and blue) into focus in the same plane.
