Concepts and technologies for optical environmental filtering with intrusion protection are provided. In an embodiment, a system can include a first intrusion detection frame structure, a second intrusion detection frame structure, a controller unit, and a laser filter frame structure that is disposed between the first intrusion detection frame structure and the second intrusion detection frame structure. The laser filter frame structure can include at least one laser emitter that projects at least one laser beam that forms a laser emission plane between the first light intrusion plane and the second light intrusion plane. The controller unit can activate at least one laser emitter, and in response to detecting an object passing through the first light intrusion plane, deactivate a laser emitter to pause creation of the laser emission plane. The controller can reactivate a laser emitter before the object passes through the second light intrusion plane.
