A miniature catadioptric lens for endoscopic imaging based on the principle of wavelength division multiplexing is presented. We demonstrate change of the magnification and the field of view (FOV) of the lens without any mechanical adjustment of the optical elements. The lens provides magnifications of ∼−1.5× at 406–750 nm and ∼−0.2× at 800 nm. The lens is used to demonstrate large-FOV (1.3 mm) reflectance imaging and high-resolution (0.57 μm) multiphoton fluorescence imaging of unstained mouse tissues.
