Optical unit (custom-made) Fθ lens unit

This is a lens used for a wide range of applications such as laser printers and laser processing.

The "fθ lens" from Daikyo Manufacturing is designed to ensure that the scanning speed is constant between the peripheral and central areas of the lens by changing the curvature of the combined lenses. The name comes from the relationship where the focal length is f, the incident angle is θ, and the image height Y is related by Y = fθ. ◆ We can make your specifications for fθ possible by designing it to meet requests that could not be achieved with off-the-shelf products! While maintaining the positional relationships of existing equipment, we aim to increase productivity for customers who want to: - "Expand the drawing area" - "Reduce the processing spot diameter," etc. We will respond to your requests! - We will customize the design and manufacture according to the applications of customers who find standard products insufficient in terms of spot size, drawing area, wavelength, etc. - Customers considering performance improvements with your products or processing machines are also welcome to contact us. 【Features】 ■ Scanning performance is better than non-telecentric systems ■ Large lens diameter
