Slow Axis Collimators (SAC-Lenses) are optical lenses that collimate diverging light from the single emitters of laser bars in the slow-axis direction. The slow axis collimators could either be a monolithic array of cylindrical micro-lenses to streamline the alignment or a single lens for a single emitter. The aspheric design of the SAC lenses results in low spherical aberrations and therefore efficient collimation of the slow-axis dimensions.
Hangzhou Shalom EO offers Custom Slow Axis Collimators (SAC-lenses) with high-precision fabrication which contributes to low scattering and crosstalk and AR coatings. The products are compatible with various laser bars and laser stacks and capable of handing high power densities. Flexible custom designs could be tailored upon request. Combined usage with our Fast-Axis-Collimators is also recommendable.
