Our Special Offers category features unique, customer-inspired calibration and test targets—available at reduced prices while stock lasts. These are bespoke designs from previous production runs, offered as one-off surplus items with the same high-precision quality as our standard products, but cannot be further configured.. These targets, including custom resolution charts, distortion grids, dot patterns, and other specialist designs, are available in chrome on glass and other substrates. Stock is limited, and once sold out, reordering is possible but requires a larger batch production. Browse our special offers now—when they’re gone, they’re gone! .
