Features 1、The field lens is mainly used for focusing 2、Suitable for semiconductor, optical fiber marking machine, etc. 3、The maximum scanning angle is ±28°, widely used 4、The field lens with different parameters has different marking ranges. The larger the marking range, the weaker the unit light intensity, and the smaller the marking range, the stronger the unit light intensity. 5、The thread interface is M85x1, easy to install and remove Specification Item Type: F-Theta Scan Lens Working Wavelength: 1064nm Maximum Scanning Angle: ±28° Thread Interface: M85 x 1 Coating: 1064nm anti-reflection coating with high damage threshold Features: Suitable for semiconductor, fiber marking machine, high cost performance Marking Range: According to customer choice Package List 1 x F-Theta Scan Lens
