• Plan-achromatic design for flat field of view and color correction
• Long working distance options for versatile applications

Description of the Module The Microscope Objective is a critical optical module used in microscopes to magnify and focus light from a specimen to form a clear, detailed image. This lens system is designed to collect light from the specimen and focus it to produce an enlarged image for observation. The quality of the microscope objective directly influences the resolution, contrast, and overall quality of the microscopic image.

Microscope objectives are typically composed of multiple lens elements arranged in a specific configuration to correct for various optical aberrations, such as spherical and chromatic aberrations. These lenses are usually mounted in a metal housing that is precisely engineered to maintain the correct alignment and spacing of the optical elements. The objective lenses may include special elements, such as aspheric lenses, to further enhance image quality and provide a flat field of view.

General Specification, Manufacturing Tolerances, and Limitations

What is the Module Composed of? And What’s the Classification?

• Optical Glass Elements: High-quality glass lenses designed to correct various optical aberrations.
• Aspheric Elements: Used to correct spherical aberration and improve image quality.
• Metal Housing: Provides structural integrity and precise alignment of optical components.
• Coatings: Anti-reflective, UV, and infrared coatings to enhance light transmission and protect the lens.
• Spring-loaded Mechanism: In some objectives, to protect the lens and specimen during focusing.

Classification

• Achromatic Objectives: Corrects chromatic aberration at two wavelengths and spherical aberration at one wavelength.
• Plan-Achromatic Objectives: Provides a flat field of view with color correction for high-quality imaging.
• Apochromatic Objectives: Corrects chromatic aberration at three wavelengths and spherical aberration at two wavelengths, offering superior image quality.
• Long Working Distance (LWD) Objectives: Designed for observing specimens with more space between the lens and the specimen.
• Oil Immersion Objectives: Utilizes immersion oil to increase numerical aperture and resolution.

What’s the Key Components?

• Lens Elements: Multiple elements to correct aberrations and focus light precisely.
• Housing: Metal housing to maintain alignment and protect the optical components.
• Coating: Multi-layer coatings to maximize light transmission and reduce reflections.
• Spring-loaded Mechanism: Optional feature in high-power objectives for specimen protection.

What’s the Critical Specs?

• Numerical Aperture (NA): Determines the resolving power of the objective.
• Magnification: The extent to which the image is enlarged.
• Working Distance: The distance between the objective and the specimen.
• Field of View: The area visible through the microscope when using the objective.
• Parfocal Distance: Ensures that the focus remains when switching between objectives.

How to Evaluate the Performance? Or What’s the Methodology How to Check the Performance? Performance evaluation includes:

• Resolution Test: Measuring the objective’s ability to resolve fine details in the specimen.
• Contrast Test: Assessing the contrast level provided by the objective in brightfield or darkfield microscopy.
• Field Flatness Evaluation: Ensuring a flat field of view across the entire image.
• Transmission Efficiency: Measuring the amount of light transmitted through the objective.

How to Select the Module Selecting a Microscope Objective involves:

• Application Needs: Consider the type of microscopy (e.g., brightfield, fluorescence) and the specimen type.
• Magnification Requirements: Choose based on the required magnification for your application.
• Numerical Aperture (NA): Higher NA for better resolution and light-gathering ability.
• Compatibility: Ensure the objective is compatible with your microscope’s tube length and mounting system.
• Special Features: Consider objectives with features like long working distance, oil immersion, or plan correction for specific applications.
