XYZ Focusing Lens Assembly, Req. 38.1 mm Plano-Convex or Bi-Convex Lens

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).
