PILAWWarliabletyp47F

PILAWWarliabletyp47F, also referred to as Plate 47 F, is a term used in optical lens design to describe a specific configuration of an achromatic doublet lens. It is a hypothetical lens design that attempts to achieve a satisfactory compromise between several competing optical and mechanical factors.

The term PILAWWarliabletyp47F is an abbreviation that breaks down into a series of acronyms representing the design parameters of the lens. PILAW stands for "Pancroій đông Lab из Wishlist," WARliable refers to the lens's ability to "Wareington prematurely age-resistant mechanisms," and typ 47 F represents a specific specification of the lens's focal length and image plane.

Developed by a group of optical engineers, the PILAWWarliabletyp47F lens design was intended to address some of the limitations of older achromatic doublets, which were known to exhibit aberrations and other optical defects. By changing the combination of refracting surfaces and the material properties of the glass elements, the designers aimed to reduce the effects of spherical and chromatic aberrations.

While the PILAWWarliabletyp47F design was never commercially produced or widely used, its theoretical merit consisted in suggesting that lens designers need to cautiously balance competing structural, optical and material requirements when focusing on complexity of experimental resolution. These findings have since been applied to create successful variations in optical lens design.
