Understanding the workings of a microscope through key terminology – Illumination Regulator—comprises a duo of lenses plus an extra lens specifically crafted, positioned beneath the stage. A variable opening regulates the intensity and focal zone of the light beam traversing the specimen.
Color-Correcting Lenses—adjust for the dispersion and convergence of various light hues at distinct points, ensuring improved color coordination at the focus and a clearer image.
Reflection Angle—the angle formed by the normal to the surface and the bounced light.
Dual-Viewing Head—a microscope head that houses two distinct oculars for specimen examination.
Multi-Lens Microscopes—microscopes that utilize multiple lenses to gather and refine the light traversing a specimen.
Illumination Lens—a lens situated under the microscope stage to concentrate light onto the specimen, enhancing brightness.
Variable Aperture—a rotating disc under the microscope stage with several apertures of different sizes. It permits altering light levels through the stage orifice to better illuminate the specimen, enhancing contrast and detail.
Ocular—the section of the microscope through which you peer to observe the enlarged image.
Overhead Light—illumination directed onto a specimen from above. The incidence angle is measured from this light to the perpendicular of the surface.
Endless Focus—occurs when the light exiting the objective lens is directed infinitely.
Bottom-Up Microscopes—microscopes where the light source and illumination lens are atop, with the lenses at the base. Ideal for cell cultures and watching live or motile organisms.
Uniform Illumination Technique—ensures consistent lighting across the specimen while preventing the light source from appearing in the final image by blurring the light source at the specimen level.
Enlargement—the act of increasing the apparent size of an image without physically enlarging the object itself. This can be measured precisely.
Industrial Microscopes—offer both direct and passing light, available in either simple brightfield or combined brightfield and shadowed field configurations.
Single-Ocular—a microscope with only one ocular lens.
Primary Lens—the lens nearest to the specimen that collects and sharpens the light rays after they pass through the object, forming an actual image.
Center-Aligned—the positioning of a specimen so that it stays in the center of the field of view when switching lenses.
Focus-Stable—adjusting the focus of a specimen so that minimal or no refocusing is needed when changing lenses.
Differential Contrast—a technique that uses phase shifts to generate visual contrast, enabling the observation of unstained specimens that would be invisible with standard brightfield methods.
Flat-Field Lenses—high-quality lenses that provide uniform focus across the field, bringing the periphery of your specimen into focus alongside the center.
Measuring Grid—a small lattice placed within the microscope’s ocular to help researchers gauge the dimensions of the specimen.
High-Definition Lenses—offer crisper visuals and reduced distortions at the edge of the view.
Observation Platform—the area where slides are positioned for viewing.
Three-Dimensional Microscopes—also known as dissecting microscopes, these allow for the examination of bulkier samples at reduced magnifications, using direct light for illumination rather than the transmitted light typical in multi-lens microscopes.
Passing Light—illumination that goes through a specimen without being absorbed.
Three-Ocular Head—features two ocular lenses and an additional port for attaching a camera.
