High-Precision Collimating Lens Micro Square C-Lens

Hobbite offers square and rectangular geometric formats to support flexible mechanical integration, where circular micro lenses cannot be tightly arranged. Coated and uncoated versions are also available for different transmission, power, and integration requirements.

We Micro Square C-Lenses are manufactured from high-quality quartz or optical glass using advanced micro-polishing and IBS coating techniques. Their compact dimensions and planar edges make them ideal for photonic chips, LiDAR transmitters, optical communication devices, VCSEL/PD arrays, and dense optical modules where rectangular alignment surfaces provide mechanical advantages.
