Meniscus SAC for Compact Designs in Blue
08 Jun 2022
With an effective focal length (EFL) of 9.7 mm, Focuslight Blue Meniscus SAC has a concave-convex, acylindrical lens design for the collimation of the slow axis of laser diodes.
Blue diode lasers continue to revolutionize the processing of different materials such as copper and aluminum. The high absorption of blue light compared to infrared light results in a great advantage for typical industrial applications such as cutting or welding. In addition to material processing, other applications in medicine (bacterial treatment and surgery), lighting, or pumping also enjoy recent interest.
Focuslight offers optimized optics for blue. A material with low absorption is the key to prevent heating and its detrimental effects. Compared to other more basic designs, the Focuslight meniscus SAC design is much more compact while maintaining minimal divergence in high-power blue lasers.
In case the effective focal length is identical, the total length of the system is much smaller compared with a regular SAC (EFLregular SAC = EFLmeniscus SAC). This enables compact designs with smaller footprints.
Focuslight produces lenses on wafers, which allows several thousand lenses to be fabricated in a single step. The result is a scalable and cost-effective production technology for very high quantities.
Founded in 2007 by Dr. Victor X. Liu and headquartered in Xi’an, China, Focuslight Technologies Inc. is a fast-growing company that develops and manufactures high power diode lasers (photon generation) and laser optics (photon control) used in various applications in advanced manufacturing, health, research, automotive and consumer electronics. Currently, our business scope is being extended by the development and manufacturing of photonic application modules and systems (photonics application solutions, including LiDAR transmitter modules and UV-L optical systems). With our extensive engineering expertise and know-how, Focuslight is dedicated to providing customers with well-matched comprehensive solutions that enable our customers’ success in their own business. In December 2021, Focuslight announced the IPO on the Shanghai Stock Exchange (Ticker Symbol: 688167), which has better positioned our future and will help us continue to unlock the future potential of photonics.
