A compound microscope is an essential optical instrument widely used in educational, medical, and research laboratories. It allows users to view tiny objects and microorganisms that are not visible to the naked eye. Understanding its types, working principle, applications, pricing in India, and financing options helps institutions and professionals make informed investment decisions.
What is a compound microscope?
A compound microscope is a microscope with two or more lenses that magnify an object in succession. The objective lens produces a real image of the object, which is further magnified by the eyepiece lens to form a clear, enlarged image.
Key features:
- Higher magnification than simple microscopes.
- Multiple lenses for precision observation.
- Suitable for biological, medical, and industrial research.
- Typically includes a light source for better clarity.
Working principle of a compound microscope
The working of a compound microscope is based on optical magnification using multiple lenses:
Step-by-step operation:
- Illumination: Light from a built-in or external source passes through the specimen.
- Objective lens: The first lens collects light and forms a real, magnified image.
- Eyepiece lens: The second lens further magnifies the real image for the observer.
- Focusing: Coarse and fine adjustment knobs help focus the specimen for clarity.
Additional points:
- Modern compound microscopes may include LED illumination, digital imaging, and binocular viewing.
- Proper cleaning of lenses ensures high-quality images.
Types of compound microscopes
Compound microscopes come in various types depending on their design and application:
- Biological microscope: Used for studying biological specimens like cells, tissues, and microorganisms.
- Binocular microscope: Equipped with two eyepieces for comfortable viewing and reduced eye strain.
- Trinocular microscope: Includes an additional camera port for capturing and recording images.
- Phase-contrast microscope: Enhances contrast in transparent specimens without staining.
- Fluorescence microscope: Uses fluorescence to observe specific components of a specimen.
- Digital microscope: Offers computer connectivity and real-time image viewing.
Uses of compound microscopes
Compound microscopes are widely used across different sectors:
- Educational institutions: Teaching biology and microbiology to students.
- Medical laboratories: Analysing blood, bacteria, and tissue samples.
- Research centres: Observing microorganisms and conducting experiments.
- Industrial applications: Examining microstructures of metals and materials.
- Pharmaceutical industry: Quality control and drug testing.
Compound microscopes price in India
Prices of compound microscopes vary depending on features, type, and brand:
- Basic biological microscopes: Rs. 5,000 – Rs. 15,000
- Binocular microscopes: Rs. 15,000 – Rs. 40,000
- Trinocular microscopes: Rs. 40,000 – Rs. 1,00,000
