Breaking Down the Features of UNICO 10x Plan Phase Long Working Distance Objective 10/0.25 for IV950 series
Specifications
The UNICO 10x Plan Phase Long Working Distance Objective 10/0.25 for IV950 series is engineered for precise microscopy, specifically designed to work with the UNICO IV950 series of inverted microscopes. Its magnification is 10x, offering a substantial increase in detail over lower power objectives. The numerical aperture (NA) is 0.25, a figure that directly relates to the lens’s ability to gather light and resolve fine details.
Crucially, this objective boasts a Long Working Distance. This specification is vital for applications where physical space between the objective and the specimen is necessary, such as live-cell imaging or manipulation. The “Plan Phase” designation indicates it is a plan achromatic objective with phase contrast capabilities, meaning it corrects for chromatic and spherical aberrations across the field of view, and it’s designed to work with phase rings to enhance contrast in unstained samples.
These specifications translate directly into practical advantages in the lab. The 10x magnification is ideal for observing larger cellular structures or scanning tissue culture dishes for specific areas of interest. The NA of 0.25 contributes to good resolution, allowing for clearer visualization of cellular components.
The long working distance is perhaps its most significant feature for certain applications. It provides ample clearance for adding reagents, manipulating cells with micro-needles, or performing operations like laser microdissection without impacting the optical path. The plan correction ensures that the entire field of view is in focus simultaneously, which is a huge time-saver and prevents frustration compared to objectives that suffer from field curvature. The phase contrast capability is a game-changer for viewing unstained, transparent biological samples, bringing out details that would otherwise be invisible.
Performance & Functionality
The primary job of any microscope objective is to produce a clear, magnified image, and this UNICO optic excels at that. Its main task is to provide high-quality, detailed views of biological specimens, and it performs this flawlessly. The 10x magnification combined with the plan phase optics delivers sharp, contrast-rich images, making it easy to identify cellular morphology and track dynamic processes.
A significant strength is the image flatness provided by the plan correction; even at the periphery of the view, details remain sharp, which is essential for accurate measurements and analysis. The phase contrast functionality is particularly impressive, rendering unstained cells with remarkable clarity and revealing fine internal structures like nuclei and organelles with excellent definition. Its ability to gather sufficient light with an NA of 0.25 means that it works effectively even in lower light conditions, minimizing phototoxicity for live-cell imaging.
The only minor point of consideration, which is inherent to its design, is that objectives with longer working distances generally have lower numerical apertures compared to high-power immersion objectives. This means that while it offers excellent detail and contrast for its magnification, it may not resolve the absolute finest subcellular structures as a 40x or 100x oil immersion objective would. However, for its intended purpose of observation and manipulation at this magnification, its performance is outstanding.
Design & Ergonomics
The build quality of the UNICO 10x Plan Phase Long Working Distance Objective 10/0.25 for IV950 series is immediately apparent. The metal barrel feels robust and precisely machined, fitting securely into the microscope turret. The overall finish is professional and resilient, showing no signs of wear even after repeated mounting and dismounting.
Ergonomically, it’s designed for efficiency within a microscope system. The 10x magnification marking is clear and easy to read, allowing for quick identification of the objective in use. The long working distance design is not only a functional specification but also enhances usability by providing that critical physical clearance needed for manipulation and sample handling.
Practical design elements include the well-defined threading that ensures a stable connection, preventing any wobble or shifting during observation. The phase ring, if applicable, is integrated seamlessly, and the lens surfaces are easy to access for cleaning, provided one uses the correct technique. It’s a component that feels built to last and function reliably in a demanding laboratory environment.
Durability & Maintenance
Given its solid construction and the typical use case for such an objective, the UNICO 10x Plan Phase Long Working Distance Objective 10/0.25 for IV950 series is built for long-term durability.

Its design doesn’t incorporate complex moving parts that are prone to failure, making it inherently robust.
Maintenance is straightforward and consists primarily of cleaning the external lens surfaces. Standard microscopy lens cleaning procedures—using specialized optical cleaning solutions and lint-free lens paper or wipes—are sufficient. It’s important to avoid touching the lens with bare fingers, as oils and contaminants can degrade image quality and potentially damage the lens coatings over time.
The primary failure point for any objective is physical damage to the lenses, such as deep scratches or chips, or contamination of the internal optical elements, which is difficult to rectify without professional servicing. However, the long working distance design, by providing more space, inherently reduces the risk of accidental impact compared to shorter working distance objectives, adding to its practical longevity.
Accessories and Customization Options
This objective is essentially a standalone component designed for a specific microscope model, the UNICO IV950 series. As such, it doesn’t typically come with accessories in the way a consumer product might. Its functionality is self-contained, and it relies on the microscope’s existing components, such as phase rings and illumination systems, to operate as intended.
There are no inherent “customization options” for the objective itself in the traditional sense; its specifications are fixed. However, its compatibility with the UNICO IV950 system is crucial. The system requires specific phase contrast rings that match the objective’s NA and magnification to achieve optimal phase imaging. Ensuring you have the correct phase ring for this 10x objective is the only “accessory” consideration that directly impacts its performance for phase contrast microscopy.
If the objective were damaged or degraded, replacement would be the only practical solution rather than repair or modification, given the precision involved. It is designed to work within the established ecosystem of UNICO microscope accessories.
