Introduction: Microscope and Objectives
A microscope is an essential scientific instrument that magnifies tiny objects beyond the capability of the human eye. At the core of its function are the objectives—the primary lenses responsible for magnifying and resolving fine details.
At Bote (www.bote.com.sg), we specialize in customized optical components, including lenses, prisms, and microscope objectives for advanced scientific, medical, and industrial applications.
What Is an Objective on a Microscope?
The objective lens is the most important component in a microscope. Positioned close to the specimen, it collects light and creates the initial magnified image.
- Objective microscope definition:
An optical lens system designed to magnify an object within a microscope. - What is an objective on a microscope?
It is the lens closest to the sample, providing the primary image that is further magnified by the eyepiece.
What Is the Function of Objectives in Microscope?
The function of objectives in a microscope includes:
- Magnification: Increases the apparent size of the specimen.
- Resolution: Determines how clearly two close points can be distinguished.
- Light Collection: Captures light from the sample and directs it to the eyepiece or camera.
- Contrast Enhancement: Specialized coatings and designs improve image clarity.
Without high-quality objectives, even the most advanced microscopes cannot deliver accurate or detailed results.
Common Types of Microscope Objectives
| Objective Lens Color Code | Magnification | Typical Use |
|---|---|---|
| Red Objective Lens | 4x (Scanning) | Overview of specimen, locating areas of interest. |
| Yellow Objective Lens | 10x (Low Power) | General viewing, structural analysis. |
| Blue Objective Lens | 40x (High Power) | Observing fine details like cells. |
| White Objective Lens | 100x (Oil Immersion) | Microbiology, bacteria study. |
- Red objective lens on a microscope:
Known as the scanning lens, it has the lowest magnification (4x) and is typically the first lens used to locate the specimen.
Advanced Microscope Objectives
Beyond standard objectives, modern microscopy uses specialized designs:
- Achromatic Objectives – Correct color distortion at two wavelengths.
- Plan Objectives – Provide a flat field of view across the specimen.
- Infinity-Corrected Objectives – Allow for additional optical components (filters, beam splitters) without degrading image quality.
- Fluorescence Objectives – Designed for use in fluorescence microscopy.
At Bote, we can provide custom coatings and high-precision optics for objectives that meet the requirements of medical imaging, semiconductor inspection, and scientific research.
