The F-1015 Precision Single-Mode Fiber Coupler uses a steering lens to achieve 0.1 micron resolution in a compact package. This coupler is very easy to use. An input iris assists in centering the laser beam. The beam passes through a steering lens, which is mounted in a precision X-Y translation assembly with 100 pitch adjustment screws. An objective lens focuses the beam on the fiber core. Translating the steering lens causes a second-order translation of the focused beam across the fiber end-face, providing 0.1 micron beam positioning resolution with negligible changes of incident angle at the fiber face.
For use with free-space laser, operating in the visible wavelength range, the F-1015 has a steering lens with a multilayer dielectric AR coating and a M-20X Microscope Objective. The effective focal length is 9 mm. This coupler is constructed of anodized aluminum and are sold without fiber chucks. The FPH-J four-jaw fiber chuck with Teflon liner for fibers less than 250 microns in diameter, and the FPH-DJ Delrin-jawed chuck for fibers 250 microns to 1 mm in diameter are the bare fiber chucks of preference. The FPH-S and FPH-S-2.5 slotted fiber chucks can also be used.
F-1015精密单模光纤耦合器采用转向透镜,在紧凑的封装中实现0.1微米分辨率。这种耦合器很容易使用。输入虹膜协助激光束居中。光束通过一个转向透镜,转向透镜安装在一个带有100个螺距调整螺钉的精密X-Y平移装置中。物镜将光束聚焦在纤维核上。转换转向透镜会导致聚焦光束在光纤端面上的二阶平移,提供0.1微米的光束定位分辨率,而光纤端面入射角的变化可以忽略不计。对于在可见波长范围内工作的自由空间激光器,F-1015有一个带有多层介质AR涂层的转向透镜和一个M-20X显微镜物镜。有效焦距是9毫米。这种耦合器是由阳极化铝制成的,销售时不含纤维卡盘。对于直径小于250微米的纤维,采用聚四氟乙烯衬里的FPH-J四爪光纤卡盘,对于直径在250微米至1mm的纤维,采用FPH-DJ dellin - jpeg - jpeg卡盘是首选的裸光纤卡盘。FPH-S和FPH-S-2.5开槽光纤卡盘也可以使用。
