Optical Surfaces Ltd. has developed a new compact beam expander that uniquely delivers high magnification (x30) from small aperture (2mm) high power laser beam lines. Traditionally the combination of ...

Benefiting from a high throughput off-axis design, these beam expanders provide an unobstructed output and highly efficient transmission. The reflective design of these beam expanders is achromatic ...

Optical Surfaces Ltd. has announced its reflective beam expanders are now available with the option to optimally operate in high vacuum environments, expanding or reducing high power laser beams.
