The 77259 X-Y-Z Focusing Lens Assembly is used to focus a collimated source onto a small target (slit, fiber, cuvette), This lower cost, stripped down version (no integral filter holder and shutter) has a larger clear aperture, 1.3 inch (33 mm), that gives you more than twice the throughput of the 77260. The 77259 uses only one lens. With a plano convex lens, the 77259 will focus a collimated beam, or collimate a diverging beam. With a bi-convex lens it will refocus a beam, but introduces a significantly higher level of spherical aberrations. The clear aperture of this assembly is 1.3 inches (33 mm), the size of the collimated beam from our 1.5 Inch Series Oriel Light Sources .Requires (1) 38.1 mm diameter Plano-convex or Bi-convex Lens (ordered separately).


77259 x y z聚焦透镜装配用于重点瞄准源到一个小目标(狭缝、纤维、试管),这种低成本,精简版(无积分滤光片夹和快门)有一个较大的光圈,1.3英寸(33毫米),给你两倍多的吞吐量77260。77259只使用一个镜头。用平面凸透镜，77259将聚焦到一个准直光束，或准直一个发散光束。使用双凸透镜，它将重新聚焦光束，但引入了明显更高水平的球面像差。这个组件的光圈是1.3英寸(33毫米)，这是我们1.5英寸系列Oriel光源的准直光束的尺寸。要求(1)38.1毫米直径的平凸透镜或双凸透镜(单独订购)。
