Choosing the Right Lens for Life Science Applications

Often overlooked in life science applications, the lens is crucial to machine vision systems. These systems, essential to life sciences, rely on the lens for medical imaging, research, microscopy, slide reading, pill counts, and pharmaceutical manufacturing and packaging quality control.¹

When selecting a lens for life sciences, one should consider the following key factors:

Application requirements

• Physical characteristics: The lens size, sensor size, mounting interface, and system compatibility.
• Resolution: High resolution, definition, and clarity are crucial for examining data and capturing precise and accurate information.
• Precise tolerances ensure consistency and reliability of the imaging results, reducing the likelihood of errors.  
• Aperture: What is the required aperture for the desired depth of field? Lenses with wider apertures (e.g., F1.4 or F2.8) offer greater creative control and perform better in dim lighting conditions.
• Coatings: Optical coatings can improve lenses' performance and functionality by modifying how they transmit, reflect, or polarize light. These coatings are applied to the lenses' optical components and can be customized to meet specific performance requirements.  
• Working Distance: Lenses with longer working distances can accommodate a broader range of sample sizes and geometries, making them suitable for diverse life science applications.

Environment

• Lighting: Are the specimens or subjects illuminated correctly? Consider the lighting when selecting the right lens for accurate observations and measurements. Whether using a microscope or imaging system, the quality and type of lighting can significantly impact your results.  
• Remote capabilities: Does the application require multiple adjustments or is the camera difficult to access? If the remote adjustment of the iris, focus, and zoom is required in the application environment using a plug and play lens like the Computar LensConnect series is essential.
• Durability and ease of maintenance: Lenses that are ruggedized and designed to withstand rigorous laboratory conditions can save time and resources. ¹

Budget

Budget constraints often play a critical role. Balancing cost with the required performance and features ensures that the selected lens provides the best value for the application's needs. Consider the long-term benefits of high-performance lenses against their initial cost, especially for critical applications.

Customization

Does the application require a custom or specialty lens? It is essential to work with a dependable manufacturer who can accommodate your specifications and produce a quality product with a low turnaround time. ²
