ISO 16505 SFR layout — five slanted squares for center-and-corner MTF across a wide field
Flat where it counts — pigment print bonded to a rigid panel; no waves, no bowing at large size
Anti-glare matte surface — controlled gloss so specular highlights don’t corrupt the edge
Three standard sizes — 2X, 4X and 5.5X, matched to ISO 16505 viewing geometry
Software-ready — analyze with the SFR module in Imatest and other ISO-12233-style slanted-edge tools
Traceable on request — measured contrast, density and dimensions; CNAS L0579, NIST & NIM traceable
