A large beam collimator is an optical component specifically designed to convert light from an optical fiber or point source into a large-diameter collimated beam. It employs an air-spaced doublet lens design, which provides superior beam quality compared to aspheric or achromatic lenses. The low-aberration lens group design achieves a beam profile closer to a Gaussian beam, with smaller divergence angle and lower wavefront error. It is suitable for applications requiring a wide beam, long-distance transmission, or broad-area illumination.
