• Microscopy ergonomics

    Upon walking in o a busy laboratory it isn't unusual to see microscopes sitting on books, tilted at odd angles, and otherwise precariously supported in a variety of positions to accommodate their users.

  • Reflected Light Microscopy

    Reflected light microscopy is often referred to as incident light, epi-illumination, or metallurgical microscopy, and is the method of choice for fluorescence and for imaging specimens that remain opaque even when ground to a thickness of 30 microns.

  • Anatomy of the Microscope - Microscope Stages

    All microscopes are designed to include a stage where the specimen (usually mounted onto a glass slide) is placed for observation.

  • Anatomy of a Microscope - Substage Condensers

    The substage condenser gathers light from the microscope light source and concentrates it in o a cone of light that illuminates the specimen with uniform intensity over the entire viewfield.

  • Anatomy of a Microscope - Field Curvature

    Curvature of field in optical microscopy is an aberration that is familiar to most experienced microscopists. This artifact is the natural result of using lenses that have curved surfaces.

  • Anatomy of a Microscope - Optical Aberrations

    Lens errors in modern optical microscopy are an unfortunate problem caused by artifacts arising from the interaction of light with glass lenses.
