Unico DIN Semi-Plan Objective

Yes, these Unico DIN Semi-Plan Objectives are precision optical components designed for demanding professional, clinical, and research environments. They are supplied in Factory New condition to ensure optimal performance.

Key features that make them suitable include:

• DIN Standard: Engineered to meet DIN specifications for standardized use.
• Compatibility: Designed for use with Unico G380/G390 and H600 Series Microscopes.
• Versatile Magnification: Available in a full range of laboratory powers: 4X, 10X, 40X, and 100X.
• Protection: The 40X and 100X objectives feature a retractable front lens mechanism to prevent damage to the objective or specimen slide during focusing.
• High Resolution: The 100X objective supports oil immersion (N.A. 1.25) for detailed high-power analysis.

These DIN Semi-Plan Objectives are specifically designed for optimal optical performance and seamless integration with the following Unico microscope series:

• Unico G380/G390 Series
• Unico H600 Series

These DIN Semi-Plan objectives provide a versatile range of magnification settings for compatible Unico microscopes, spanning from low-power scanning to high-resolution detail:

• 4X (N.A. 0.10)
• 10X
• 40X (N.A. 0.65)
• 100X (N.A. 1.25)

For enhanced protection, the 40X and 100X objectives feature a retractable front lens mechanism to help prevent damage to the slide or the lens during focusing. The 100X objective is specifically designed for oil immersion to maximize resolution.

The protective retractable front lens mechanism is a specialized feature included on the higher-magnification objectives in this series. This mechanism is crucial for preventing damage to both the lens and the specimen slide during focusing, especially at high power.

The objectives equipped with this feature are:

• 40X (N.A. 0.65)
• 100X (N.A. 1.25), which is the oil immersion objective.

Yes, oil immersion is required specifically with the highest magnification objective to achieve maximum resolution and the highest Numerical Aperture (N.A.). This practice is essential for detailed analysis at high power.

• The 100X objective (N.A. 1.25) is the only objective in this series designed for oil immersion use.
• The 4X, 10X, and 40X objectives are intended for dry use.
• For enhanced protection during focusing, the 40X and 100X objectives feature a retractable front lens mechanism.

Yes, the 100X Unico DIN Semi-Plan Objective features a high Numerical Aperture (N.A.), which is essential for maximizing resolving power and clarity in high-magnification viewing.

Key specifications include:

• Numerical Aperture (N.A.): 1.25
• Required Use: This objective is designed for oil immersion to achieve optimal performance and resolution.

The 10X Unico DIN Semi-Plan Objective features a Numerical Aperture (N.A.) of 0.25.

This specification provides excellent resolution and light-gathering performance suitable for high-quality medium-power observation in laboratory settings.

The Numerical Aperture (N.A.) for the 4X Unico DIN Semi-Plan Objective is 0.10.

This low-power objective is specifically designed for:

• Scanning and orientation of samples.
• Compatibility with Unico G380/G390 and H600 Series Microscopes.

As a Semi-Plan objective, it also helps enhance the resolving power and field flatness of your compatible microscope system.

Yes, the specialized high-power objectives include a retractable front lens, which is a crucial safety feature. This design minimizes the risk of damage to the objective lens or the specimen slide during focusing.

• 40X Objective (N.A. 0.65)
• 100X Objective (N.A. 1.25 Oil Immersion)

This feature is particularly valuable when using the 100X objective with oil immersion due to its close working distance.

The 40X Unico DIN Semi-Plan Objective has a Numerical Aperture (N.A.) rating of 0.65.

Since this is a high-power objective, it also incorporates a key safety feature:

• Retractable Front Lens: This design is crucial for preventing damage to the objective or the specimen slide during focusing, offering enhanced protection during high-magnification use.
