The Edmund Optics 58430 1.0x Silvertel Telecentric Lens is an essential addition to any imaging system that demands high-quality, accurate, and precise optics. This telecentric lens boasts a working distance of 83mm and a closed aperture of 114mm, making it an ideal choice for applications where the image plane and the object axis need to be parallel.
The Silvertel telecentric lens is designed with a 1.0x magnification factor, meaning it produces an image that is the same size as the original object. This feature is particularly beneficial in applications such as metrology, machine vision, and inspection systems, where maintaining consistency in image size is crucial.
One of the most prominent features of this lens is its telecentric design. Telecentric lenses provide several advantages over standard lenses. They eliminate parallax errors, ensure that the entire object is in the plane of focus, and provide a larger depth of field. These features result in improved image quality and increased measurement accuracy.
The lens has a focal length of 6mm when closed, and it is suitable for applications where a short working distance is required. The lens barrel is manufactured from high-quality aluminum, ensuring durability and stability. The lens also features a C-mount threading, which is a common mounting standard for industrial imaging applications.
The Edmund Optics 58430 1.0x Silvertel Telecentric Lens is designed and manufactured to meet the highest standards of optical performance. It undergoes rigorous testing to ensure that it meets the required specifications for resolution, distortion, and other optical parameters. The lens is also coated with Edmund Optics' proprietary Silvertel coating, which provides excellent reflectivity and reduces stray light.
In summary, the Edmund Optics 58430 1.0x Silvertel Telecentric Lens is a versatile and high-performance optic that is suitable for a wide range of industrial imaging applications. Its telecentric design, short working distance, and excellent optical quality make it an ideal choice for metrology, machine vision, and inspection systems. The lens's robust construction, C-mount threading, and Silvertel coating further ensure that it can withstand the rigors of industrial use while delivering accurate and precise images.
a. Parallel rays: The rays of light from the object intersect at a single point behind the lens, ensuring parallel rays at the image plane.
b. Improved resolution: Telecentric lenses offer increased resolution and accuracy as they eliminate the effects of geometric distortion.
c. Consistent sensitivity: Telecentric lenses provide consistent sensitivity across the entire field of view, making them ideal for applications such as machine vision and metrology.
2. High Numerical Aperture (NA): With a high NA of 0.25, this lens can capture a significant amount of light, making it suitable for low-light applications.
3. Wide Field of View (FoV): The lens offers a wide field of view of 114mm, which is beneficial for capturing large objects or fields.
4. Compact Design: The lens has a compact design, making it suitable for applications where space is limited.
5. Affordability: The Edmund Optics 58430 1.0x telecentric lens is relatively affordable compared to other telecentric lenses from leading manufacturers.
6. Limited Working Distance (WD): The lens has a working distance of 83mm, which may not be suitable for all applications. Shorter working distances may limit the size of the objects that can be captured.
7. Manual Focus: The lens does not come with an autofocus mechanism, which may require additional manual effort to achieve the desired focus.
8. F-number: The lens has an f-number of f/6 when closed, which may result in a narrower depth of field, making it challenging to keep the entire object in focus.
9. Limited Coating Options: The lens may not offer advanced coating options, which could impact its performance in specific applications, such as high-contrast or high-reflectivity environments.
In conclusion, the Edmund Optics 58430 1.0x telecentric lens offers several advantages, including telecentricity, a high NA, wide FoV, compact design, affordability, and improved resolution. However, it also comes with some disadvantages, such as a limited working distance, manual focus, and a narrower depth of field (f/6 when closed).
Based on the pros and cons, the lens is recommended for applications that require telecentricity, a wide field of view, high resolution, and a compact design. It is also suitable for low-light applications due to its high NA. However, it may not be the best choice for applications that require a longer working distance, autofocus, or advanced coating options.
