Our 77258 is a simple lens holder, frequently used for focusing the output of a collimated source onto a monochromator. It features precise 2 mm X and Y adjustments, has a large 1.38 inch (35 mm) clear aperture, and has a 1.5 Inch Series female flange for direct coupling to Oriel instruments. It was designed as an alternative for those who don’t need a lens holder with focus adjustment or an integral filter holder and manual shutter, like the 77260 and 77330 Focusing Assemblies.
