F-theta Scan Lens Field Lens for Fiber /co2 Laser Marking Machine Parts
Product Description:
In imaging optics, a field lens is a positive-powered lens or group of lenses that comes after the objective lens and before the image plane or the eyepiece, serving to change the size of the image,or to provide image-space telecentricity.
Product Application:
"Laser marking" stands for marking or labeling of workpieces and materials with a laser beam. In this regard, different processes are distinguished, such as engraving, removing, staining, annealing and foaming. Depending on the material and the quality requirement, each of these procedures has its own advantages.
1) Free Training by VCD:We will supply the machine with <Training VCD> , <User's Manual> and <Instruction Book> in English for installing, operation, maintenance and trouble-shooting, and shall give technical guide by E-mail, fax, telephone, MSN, ICQ and so on, when you meet some problems of installation, using or adjusting.(Recommend)
2) Free Training Factory:You can send op erator to laser marker factory for free training. Laser marker will offer professional guide for free.It is direct and effective face-to-face training.Here we have well-assembled equipments, all sorts of tools and testing facility.
Training Time:2-3 days (Recommend)
3) Our engineer can do a door-to-door instruction training service at your local site.We need your help to deal with the visa formality, prepaid traveling expenses and accommodation to us during the business trip and service period before their dispatch.It's better to arrange a translator for both of our engineers during the training period.

A. The scan lens is optimized to provide a flat field image with diffraction-limited spot size in micron scale over the entire scan field.
B. The image field height is almost directly proportional to the scan angle. Typically, the linearity f-theta distortion is kept less than 1% without software correction to ensure minimal distortion. High transmissive AR coating is coated onto the lens elements surface to ensure minimal power loss and hence increase the throughput.
C. The scan lenses are designed with a industrial standard mount threading to facilitate lens installation into laser machine.
D. To accommodate different standard mount thread, mount adaptors are available for ease of conversion.
E. Most of our products are RoHS compliant unless otherwise stated.
F. Aperture Stop is set at center point of X-Y mirror in case of two axis scanning system.
