Zoom lighting device and optical apparatus

The invention provides a zoom lighting device and optical equipment, and the zoom lighting device comprises a light source which is used for generating an incident light beam; the light path system comprises a reflecting mirror, a first microscope objective, a broadband polarization beam splitting cube and a second microscope objective which are sequentially arranged on a main optical axis of the light path system, the main optical axis is perpendicular to the direction of the incident light beam, and the broadband polarization beam splitting cube is used for splitting the incident light beam to obtain a first light beam propagating in the direction of the first microscope objective; the reflector is used for reflecting the first light beam, the first microscope objective is used for focusing the first light beam, and the second microscope objective and the first microscope objective are symmetrically arranged; and the vibration source is connected with the reflector and used for driving the reflector to vibr
