摘要： An apparatus and a method for changing optical tweezers are provided. The apparatus includes a diffractive optical element (DOE), a mask unit and an objective lens. The DOE includes a plurality of phase delay patterns. The mask unit includes a plurality of mask patterns that correspond to the phase delay patterns, respectively, wherein at least a portion of the mask patterns are complementary. A laser beam passing through each phase diffractive pattern correspondingly passes through each mask pattern to generate a compound diffractive pattern. The objective lens receives the compound diffractive pattern and focuses it on an examining object to form an optical tweezers.

摘要： An apparatus of generating an optical tweezers with momentum and method thereof and an optical tweezers photo-image for guiding particles are provided. The apparatus generates at least one optical tweezers on an examined object that carries at least one particle. The apparatus includes a laser source, a diffractive optical element and a convergent lens. The laser beam from the laser source passes through the diffractive optical element to produce a diffractive pattern. The laser beam is then received by the convergent lens and then to be focused on a plane of the examined object. The optic axis of the convergent lens is substantially not perpendicular to the plane of the examined object, so that the laser beam is projected onto the plane of the examined object in a skewed manner for providing a lateral momentum to move the particle.

摘要： An optical tweezers controlling device including a light source, an objective lens and a focus adjusting unit is provided. The focus adjusting unit disposed between the light source and the objective lens includes a mirror set and a zoom lens set. The mirror set has at least a mirror. The mirror is rotatable such that after a light of the light source is projected to the mirror, the reflective direction of the light reflected from the mirror is changeable. The zoom lens set has at least a zoom lens disposed in accordance with the mirror. By rotating the mirror or changing the focal length of the zoom lens, the focusing location of the light changes on the focal plane of the objective lens or in the front or the rear of the focal plane.

摘要： An optical tweezers lifting apparatus is provided. The optical tweezers lifting apparatus includes an optical tweezers and a particle-lifting device. The particle-lifting device includes a substrate and a plurality of electrodes that are disposed on the bottom of a flow path in the substrate. When a dielectrophoresis (DEP) solution with a plurality of floating particles is conducted into the flow path and upon those electrodes and a voltage is applied to these electrodes, these particles would be driven by a negative DEP force to move upward to a specific depth in the flow path. Meanwhile, the optical tweezers of the apparatus is selectively focused at the specific depth in the flow path.
