Fiber Laser Focal Lens With Monitor, for fiber laser cutting!
The Feature and Application:
Coupled with fiber laser this system could be used for laser collimating and focal. The most important is that the working plane could be monitored. So the lens is widely used in fiber laser cutting machine.
The principles：
This system consists of one collimator, one focal lens and one imaging lens, which is shown in following picture.
The laser beam input from the port is collimated by the collimator. The collimated beam is reflected to laser delivery which can focal the beam into a spot on the working plane. At the same time the working plane is imaged to the imaging plane through the delivery and imaging lens. So finally with the help of a camera with C mount you will get a video of working plane in time.

Microscopic inspection systems for laser micro-fabrication
A microscopic imaging system is a necessary accessory for a laser micro-fabrication/manipulation system to find the focus plane and monitor the process quality. A schematic layout of such a system is seen in Fig. 1. and real system setup in Fig. 2.
