Standard on all Brightfield and Polarizing models is a C-BF spherically corrected Abbe, N.A. 1.25 condenser. Its main aspherical lens and additional swing lens make the Brightfield extremely effective with both low- and high-power objectives. It has a built-in aperture diaphragm, and its swing-out filter holder (Ř33mm) accepts an array of filters. |
