Experience enhanced visual clarity and resolution with the High-Quality 4.2mm Microscope Objective (NA0.65/1.25/0.25) from a renowned manufacturer, available through SPI (16mm 43). This objective lens is specifically designed for applications that demand exceptional optical performance and precise detail in imaging.
The objective lens features a numerical aperture (NA) of 0.65, 1.25, and 0.25, allowing for versatile imaging in various lighting conditions. The high NA of 1.25 offers superior resolution and brightness, while the low NA of 0.25 provides a wider field of view with reduced aberration. The 4.2mm focal length enhances the ability to capture fine details, making it suitable for observing samples at intermediate magnifications.
Constructed with premium materials, this objective lens ensures durability and long-lasting performance. The lens element is coated with advanced multi-layer coatings to minimize reflection and maximize light transmission, resulting in brighter, clearer, and more accurate images. The lens barrel is designed for easy handling and compatibility with a wide range of microscope setups.
Measuring 16mm in length and 43mm in diameter, this microscope objective is a perfect fit for most standard microscopes. The compact design ensures portability and ease of use, making it an ideal choice for researchers, educators, and enthusiasts alike.
In summary, the High-Quality 4.2mm Microscope Objective (NA0.65/1.25/0.25) offers exceptional optical performance, versatility, and durability, making it an essential tool for anyone seeking precision imaging in their research or study. Choose SPI (16mm 43) for this high-quality objective lens and elevate your microscopic observations to new heights.
1. High Numerical Aperture (NA) of 1.25: This high NA value allows for increased resolution and light gathering capacity, making it suitable for high-magnification, low-light applications.
2. Diverse Usage: The 10x magnification provides a balance between field of view and resolution, making it a versatile choice for various microscopy tasks.
3. Short Working Distance (WD) of 4.2mm: A shorter WD means the objective can be placed closer to the sample, which can be beneficial for observing thick or delicate samples.
4. Compatibility: This objective is designed to fit standard microscope bodies, ensuring compatibility with a wide range of microscopes.
Cons:1. Not Ideal for Low-Magnification Work: With a maximum magnification of 10x, this objective may not be the best choice for large field-of-view applications or low-power observation.
2. High Cost: Due to its high-quality components and advanced features, this objective may be more expensive compared to other objectives with lower specifications.
3. Potential Chromatic Aberration: The presence of two different NAs (0.65 and 0.25) might lead to chromatic aberrations, causing colored fringes around the edges of objects. However, this can be minimized with proper microscope setup and adjustments.
Conclusion:The NA0.65 1.25 NA0.25 10 4.2mm Microscope Objectives (SPI 16mm 43) offer advanced features such as high resolution, light gathering capacity, and a short working distance, making them suitable for high-magnification, low-light applications. However, their relatively high cost and potential chromatic aberration should be considered.
Recommendation:If you require high-magnification, high-resolution observations and are willing to invest in a high-quality objective, this product could be a good choice for your microscopy needs. However, if you need a more versatile objective for various tasks or a lower-cost option, you may want to consider objectives with a lower magnification or different specifications. Always ensure the objective is compatible with your microscope and that you have the necessary equipment to minimize any potential chromatic aberration.
