glycerinobjektiv
Glycerinobjektiv, also known as glycerin-filled or glycerin-immersion objectives, are specialized microscope objectives designed to enhance resolution and contrast in optical microscopy. These objectives utilize a glycerin (glycerol) medium between the specimen and the lens to reduce light refraction and scattering, thereby improving image clarity. Glycerin has a refractive index (1.47) that closely matches that of many biological tissues, minimizing optical aberrations compared to air or water immersion objectives.
The primary advantage of glycerinobjektiv lies in their ability to minimize spherical and chromatic aberrations, particularly
These objectives are typically used in conjunction with a matching immersion medium, ensuring consistent optical performance.
Glycerinobjektiv is often employed in fluorescence microscopy and phase-contrast imaging, where high contrast and resolution are
