F-Theta Catalog 2023

Product catalog summary

Overview: Opto5's F-Theta lenses are designed for laser marking applications, offering a range of focal lengths and mounts to ensure uniform beam quality and precise spot positioning. These lenses are optimized for Nd:YAG high power lasers.

Specifications:

M39 Mount Series: Available for 1064 nm and 532 nm wavelengths with nominal focal lengths of 100 mm, 160 mm, and 254 mm. Features include a scan field ranging from 44x44 mm to 161x161 mm, and total transmittance over 96%.
M85 Mount Series: Designed for 1064 nm wavelength with focal lengths of 100 mm and 160 mm. Offers a scan field of 72x72 mm to 102x102 mm, with total transmittance over 95%.
M85-M55 Mount Flat Field / Double Flange Series: Provides enhanced field flatness with focal lengths of 100 mm, 160 mm, and 254 mm. Scan fields range from 72x72 mm to 182x182 mm, maintaining total transmittance over 96%.

Key Parameters:

F-Theta Distortion: Less than 1% for most models, ensuring minimal distortion across the scan field.
Spot Diameter: Varies by model, with smaller diameters for higher precision marking.
Field Curvature: Maintained below 0.30 mm for flat field series, enhancing image quality.

Design Considerations: The lenses are designed with optimal glass selection and coating to support high power laser applications, ensuring durability and performance.
