Study Guide Lab Exam 1 LAB 1: Digital Microscopy of Live Cells 1. Compare and contrast brightfield, darkfield, and phase-contrast optics. Brightfield: background is brightly lit and only colored specimens that absorb light at particular wavelengths/reflect or refract other wavelengths produce any contrast; best used to view dead stained cells or live cells with naturally-occurring pigments (though most live cells are nearly transparent and lack sufficient contrast to be adequately seen ((with brightfield optics.)) Condenser should be lowered as much as possible. Darkfield: background is dark/black and only light from the outer edge of the light source (from a disc placed in the condenser) that surrounds the specimen, making it bright white, is
