We announce avaibility of folded grin cylindical lens. The lens collimates the light from laser diodes and changes the beam direction for 90 degrees. The beam direction change can be adjusted to tightest tolerance. The curved sides of a lens have AR coating while flat side has reflective coating. The lens is made using a new fabrication process that improves the lens quality without affecting its legendary ease of alignement. For now, we offer lens with 0.75 mm radius. Other sizes are possible if needed.
Cylindrical lenses are used to shape light in one axis. They are commonly used as laser diode collimators and for laser diode to fiber coupling. Rod and doric™ GRIN lenses are used in ultra compact systems, while large radius are used when space is not limited. Look the product Cylindrical lenses
