A laser beam expander is designed to increase the diameter of a collimated input beam to a larger collimated output beam. Beam expanders are used in applications such as laser scan-ning, interferometry, and remote sensing. Contemporary laser beam expander designs are afocal systems that developed from well-established optical telescope ...
Beam expanders have two main purposes in the laser industry. Increased power density in the focal point. In order to obtain an increased power density in the focal point, the incident beam is expanded to its maximum.
Standard Laser Beam Expanders. Many applications of helium neon and other visible lasers require thebeam to be expanded for uniform illumination of a large area.CVI Melles Griot has developed a cost-effective range of beam expanders which are guar-anteed to produce 1l or less of peak-to-peak wavefront distortion.
Motorized Zoom Laser Beam Expander, covering a wider range of wavelengths than conventional products. Lens design that takes wavefront aberration into consideration allows use in advanced optical systems such as interferometry and laser processing.
laser processing with lens designed for wave from aberration. The beam expander optical system is air-space with no bonde. lenses and can be used for high powered laser applica-tions. With the Galilean type lens configuration, it reduces the number of aberra.
Small, lightweight and easy-to-install, our BE-Se-ries Beam Expanders expand and collimate the beam diameter of your laser’s output by 3x, 4x or 5x, to reduce or eliminate damaging hot- spots and optics damage that can sometimes occur in harsh operating environments.
It is high-power zoom Laser beam expander. It supports a broader wavelength range than the current models. It can be used in an optical system with high precision, such as a laser interferometer and processing by the lens design that takes into account the wavefront aberration.
