Red Laser LDC-660
LDC-660 is a fiber-coupled semiconductor laser introduced by the company for red-light indication. Its coaxial package is compact and small, with a wide operating temperature range. A built-in 1064nm protection structure prevents laser damage. It is particularly suitable as an indicator source for integration into fiber-laser and similar systems.
