Unico DIN Achromat Objective

These Unico DIN Achromat Objectives are factory new.

These objectives utilize the DIN Standard thread mount, which means they are mechanically interchangeable with many other microscopes adhering to the same standard.

However, for guaranteed performance, these objectives are specifically designed and optically optimized for seamless integration with Unico microscope systems. They are intended for the following series:

• M250
• M280
• G380/G390
• G500
• H600
• IP730

To ensure the best optical results, using them with these designated Unico models is recommended.

Yes, select higher magnification objectives in the Unico DIN Achromat series are equipped with a retractable front lens mechanism.

This design serves as a crucial safety feature, preventing potential damage to the objective tip or the specimen slide during high-power focusing maneuvers.

The retractable feature is typically available on the 40X, 60X, and 100X objectives, depending on the specific Unico microscope series configuration (e.g., M250, M280, G380, G500, H600, IP730).

Note: The 100X objective is specifically designed for use with immersion oil to achieve its maximum Numerical Aperture.

These DIN Achromat Objectives are engineered for wide compatibility and standardized performance across several Unico microscope platforms.

They are compatible with the following Unico series:

• M250
• M280
• G380/G390
• G500
• H600
• IP730

Adherence to the DIN Standard ensures reliable mechanical and optical interchangeability within these systems.

Yes, many of the high-magnification objectives are equipped with a retractable front lens.

This safety feature is designed to protect both the delicate objective element and the specimen slide from accidental damage during close focusing, which is common when viewing samples at high powers.

Retractable lenses are generally included on the following objectives, though specific configurations depend on the chosen microscope series:

• 40X
• 60X
• 100X (This objective also requires oil immersion for optimal performance.)

The highest magnification objective, the 100X (N.A. 1.25), requires the use of immersion oil. This is standard for high-power microscopy as oil immersion is essential for achieving maximum resolution and light collection at this numerical aperture level.All other magnifications in this series (4X, 10X, 20X, 40X, and 60X) are designed for dry use only.

The objective that requires immersion oil is the highest magnification option, the 100X DIN Achromat Objective (N.A. 1.25).

Using immersion oil with this objective is critical to:

• Maximize the Numerical Aperture (N.A.) for optimal light gathering.
• Achieve the highest possible resolution and clarity needed for high-power observation.

Yes, these Unico DIN Achromat Objectives provide clear, reliable optical performance suitable for a variety of laboratory and educational applications. These components are designed as essential upgrades or replacements for several Unico microscope platforms (M250, M280, G380/G390, G500, H600, IP730 Series).

Image clarity and detail are ensured by:

• Achromatic Correction: The DIN Achromat design corrects chromatic aberrations, resulting in sharp contrast and accurate color fidelity for microscopic observation.
• High Resolution Range: The objectives offer Numerical Apertures (N.A.) ranging from 0.10 (4X) up to 1.25 (100X), maximizing the visibility of fine specimen details.
• Immersion Use: The 100X objective requires immersion oil to achieve its maximum N.A. (1.25) and highest resolution potential.

The Unico DIN Achromat Objectives are offered in a comprehensive range of magnifications, suitable for diverse laboratory applications, from low-power scanning to high-resolution immersion work. All objectives utilize DIN Standard Achromat correction for sharp, clear imaging.

Available Magnification Options

Special Features:

• Retractable Lenses: High-power objectives (40X, 60X, and 100X) in select configurations (e.g., M250, M280, H600 series) feature a retractable front lens mechanism to help prevent accidental damage to the objective or the slide.
• Oil Immersion: The 100X objective specifically requires the use of immersion oil to reach its maximum Numerical Aperture (N.A. 1.25) for optimal resolution.

The Numerical Aperture (N.A.) for the 4X objective is 0.10. This lower N.A. is standard for this power, as the 4X objective is typically used for general viewing and rapidly locating a specimen on the slide.
