Available in this sale is a JML Optical Industries 12in/305mm f/9 lens with diaphragm and flange. We are unsure if the lens is complete or it’s designed purpose. “Who is JML Optical Industries,” you ask? From Bloomberg’s website : “JML Optical Industries, LLC designs, engineers, manufactures, and tests custom optical assemblies, components, and systems. It provides multi-element assemblies, such as lenses; and optical components, including singlets, achromats, mirrors, prisms, beam-splitters, and windows, as well as offers optical coating services. The company serves various industries that use imaging optics, including defense, medical and bio-medical diagnostics, life science research, metrology, biometric, and other image-using original equipment manufacturer industries worldwide. JML Optical Industries, LLC was founded in 1972 and is based in Rochester, New York.” The lens’ optics have a number issues: element separation, compromised coatings and marks in the glass. There is a single element group (front) and we are uncertain if the lens is complete or requires a rear element group to function as it’s original design intended. The structure provides for screwing a rear element group into the unit. It may possibly be employed as a soft focus lens for shooting or diffuse enlarging lens.
That being said, the truly interesting parts here are the working diaphragm and mounting flange. The diaphragm is comprised of 15 blades, makes a near perfect circle at all apertures and adjusts smoothly. The flange is in excellent condition, the working diaphragm (there is no shutter here) is supremely usable and the flange is in superior condition. It will provide a fine basis or completion piece for your photographic engineering project.
