Product Detail
The 0.58 N.A., 15X Fixed Cassegrain Objective has a working distance of 15 mm. Objectives are available with three compensation configurations - zero, 1 mm, and 2 mm. The zero compensation objective is optimized for transmission/reflectance measurements when no window material is above the sample, the 1 mm compensation objective is optimized for measurements when a 1 mm thick window is above the sample, and the 2 mm compensation objective is optimized for a 2 mm window above the sample.
