Telecentric F-Theta Lenses: Precision Optics for High-Accuracy Laser Processing

1.Optical Performance

Spot uniformity: The focal spot size is uniform across the entire field of view.

Energy distribution: Stable energy density for consistent results.

Spot shape: Maintains a circular beam profile even at the edge of the field.

Aperture and focal length: JGZOE offers a variety of specifications are available to match different laser powers and processing areas.

2. Materials & Coatings

Made of high-transmittance materials such as fused silica or zinc selenide, the coatings are optimized for wavelengths (1064nm, 355nm, 532nm, 10.6μm) for maximum efficiency and durability, and have a high laser-induced damage threshold (LIDT) to withstand high-power laser exposure.

3.Applications

Laser marking, cutting, engraving, and micro-processing across industries such as electronics, automotive, jewelry, and medical devices.

4.Durability & Maintenance

Dust-proof and scratch-resistant design ensures long service life. Easy to clean and maintain, reducing downtime and protecting your investment.

5.Compatibility

The product is compatible with fiber lasers, CO2 lasers, UV lasers, and most mainstream galvanometer scanning systems.

6.Price & Lead Time

JGZOE offers competitive pricing and stable supply ensure cost-effectiveness without compromising performance.

7.Case Study

A German electronics manufacturer integrated our telecentric F-Theta Lenses into its UV laser marking system. The result: an accuracy of ±0.01 mm over a range of 200 mm and a 25% increase in production efficiency.

 8. Common Misconceptions 

Assume that all F-Theta lenses are telecentric (most are not).

Ignore coatings for specific wavelengths.

The wrong focal length was chosen for the intended use.
