While many loupes compromise resolution near the edges of their viewing field, the Dimension 3 set the standard for edge-to-edge resolution over a decade ago. The oldest optical design in the Orascoptic portfolio, this economically priced 2.5x power loupe is tried and true. The Dimension 3 features classic round oculars that deliver a large viewing field. These telescopes help to simplify instrument transfer for optimum hand-eye coordination.
