  • Design of an achromatic high numerical aperture optical ...

    well the beam is collimated. This lens can represent any imaging system placed before the detector of the optical fiber used in detection. Finally the achromatic range is defined by imposing that the chromatic focal shift is zero at both 600 nm and 750 nm (Fig. 4) when the system is excited with a collimated beam with 10 mm diameter. Figure 4.

  • Rifle Scope Objective Lens Diameter Guide: Choose The Best ...

    Larger objective diameter lens can quickly add to the overall weight of the rifle scope ultimately making it top heavy and awkward. Those with adjustable objectives (AO) also tend to be the heifers of the lot since added glass weight can get cumbersome.. So if you're concerned with weight bulkiness and wieldability you'd probably want to go with a standard 40 mm lens.
