Cons:1. Price: Splan objectives are relatively expensive compared to other objective types.
2. Weight: The apochromatic design and high-quality glass used in these objectives make them heavier than other objectives.
Olympus APO4 Objectives: Pros:1. High resolution: The Olympus APO4 objectives provide excellent resolution and image quality, comparable to the Splan series.
2. Compact design: These objectives are more compact than the Splan series, making them easier to handle and transport.
Cons:1. Field of view: The field of view is slightly narrower compared to the Splan series.
2. Limited options: Olympus APO4 objectives are available in fewer magnification levels than the Splan series.
DPlan Objectives: Pros:1. Affordability: DPlan objectives are less expensive than Splan and Olympus APO4 objectives.
2. Wide field of view: DPlan objectives offer a wider field of view compared to the Splan and Olympus APO4 objectives.
Cons:1. Resolution: The resolution and image quality of DPlan objectives are not as high as the Splan and Olympus APO4 objectives.
2. Chromatic aberrations: DPlan objectives may have more chromatic aberrations due to their lower price point.
APO10 Set: Pros:1. Cost-effective: The APO10 set provides a more affordable solution for users who need a variety of objectives for different applications.
2. Compatibility: The APO10 set is compatible with various microscope brands and can be a good choice for users who need flexibility.
Cons:1. Resolution and image quality: The individual objectives in the APO10 set may not match the resolution and image quality of the Splan, Olympus APO4, or individual high-end objectives.
2. Lack of specific objectives: The APO10 set does not include some specific objectives, such as the 60x oil immersion, which may be necessary for certain applications.
Conclusion:Each objective type has its strengths and weaknesses. If budget is not a concern, the Splan AP020 and Splan APO40 objectives offer excellent resolution and image quality, making them suitable for detailed research and imaging. For users who prioritize compactness, the Olympus APO4 objectives are a good choice. For those on a tighter budget, the DPlan objectives offer a more affordable solution with a wider field of view. The APO10 set provides a cost-effective and flexible option for users who need a variety of objectives for different applications but may not require the highest resolution and image quality.
Recommendation:If resolution and image quality are the top priorities, the Splan AP020 and Splan APO40 objectives are the best choice. For users who prioritize compactness, the Olympus APO4 objectives are recommended. If budget is a concern, the DPlan objectives are a more affordable option. The APO10 set is recommended for users who need a variety of objectives for different applications but do not require the highest resolution and image quality. Ultimately, the choice will depend on the specific requirements and budget of the user.
These objectives are for olympus microscope, they appear to be in good cosmetic condition and doesn't appear to have optical obstruction.
They do have normal wear marks and scratches but nothing gross. I look through them in daylight and they look good. No crack or scratches. Please see pictures.
