Product Description

General Introduction: 
Raytek F-theta lenses have been engineered to provide the highest performance in laser scanning or engraving systems. These lenses are ideal for engraving and labeling systems, image transfer, and material processing. For many applications in laser scanning and engraving, a planar imaging field is desired for the best results.

Main Characteristics:
1) .Various focal length specifications are available;
2) .Each element is coated with a high efficiency antireflection film;
3) The design of multi element air gap with diffraction limit is adopted;
4) .Large scan range
5) .Provide flat image plane and low f-theta distortion
6). The scanning mirror can operate at a constant angular speed, which greatly simplifies the control circuit
7). It is widely used in vibroscopic scanning, laser marking, laser carving and cutting system;
8). Air-spaced 3 or 4-element designs;
9).Transmission of > 90%;
10).Raytek F-Theta condition accuracy of better than 0.1%;
