Conventional microscopes, which rely on multiple objective lenses for varying magnifications, are bulky, complex, and costly, making them difficult to integrate into compact devices. They require frequent manual adjustments, complicating the imaging process increasing maintenance burdens. This paper explores potential of single ultrathin graphene metalens address this issue. We propose demonstrate a 200 nm thin multiaxial focus with high-quality focusing, designed using spatial multiplexing fabricated by one-step laser nanoprinting. A five-focal has been created, achieving clear magnifications across broadband covering entire visible wavelength. The significantly reduced size system orders magnitude holds profound facilitating integration miniaturization optical microscopic systems.
