Slow-axis collimator features acylindrical lens design

A blue meniscus slow-axis collimator (SAC) has an effective focal length (EFL) of 9.7 mm and a concave-convex, acylindrical lens design for the collimation of the slow axis of blue laser diodes. Due to the high absorption of blue light compared to infrared light, applications for the meniscus SAC include cutting or welding of different materials such as copper and aluminum. Other applications include medicine (bacterial treatment and surgery), lighting, or pumping.

A material with low absorption is the key to prevent heating and its detrimental effects. The meniscus SAC design is compact while maintaining minimal divergence in high-power blue lasers.
