The Coherent 34-3517-000 25.4mm Diameter Calcium Fluoride Plano Convex Lens (PCX, 75mm Focal Length) is a precision-engineered optical component, designed for applications requiring exceptional clarity, high transmission, and excellent thermal and chemical stability.
This lens, with a diameter of 25.4mm, offers a large aperture, allowing for maximum light gathering capabilities. The plano-convex (PCX) design ensures a flatter surface at the front (plano) and a curved surface at the back (convex), which is ideal for use as a collimating or focusing element in various optical systems.
The lens features a 75mm focal length, making it suitable for telephoto applications. It is crafted from calcium fluoride (CaF2), a material known for its ultra-low dispersion properties, which significantly reduces color fringing and chromatic aberrations, resulting in superior image quality.
The Coherent 34-3517-000 lens is manufactured to rigorous standards, ensuring the highest levels of optical performance. Its surface quality is excellent, with a low scatter coefficient to minimize light loss. The lens is also resistant to thermal shock and various chemicals, making it durable and reliable for use in demanding environments.
In summary, the Coherent 34-3517-000 25.4mm Diameter Calcium Fluoride Plano Convex Lens (PCX, 75mm Focal Length) is an excellent choice for applications requiring high transmission, low dispersion, and exceptional thermal and chemical stability. Its large aperture, plano-convex design, and telephoto focal length make it versatile for a wide range of optical applications.
1. High-Quality Material: The lens is made of Calcium Fluoride, known for its excellent optical properties, including high transmission over a broad spectral range, low dispersion, and high thermal stability. This makes it suitable for applications that require high-quality optics.
2. Large Diameter: With a diameter of 25.4mm, this lens allows for a larger aperture, which can result in increased light gathering capabilities, better image brightness, and shallower depth of field in certain applications.
3. Long Focal Length: The 75mm focal length provides a relatively narrow field of view, making it ideal for applications that require a high degree of magnification or a more focused image.
4. Flat Surface: The plano convex design ensures that one surface of the lens is flat, which can simplify the optical system design and reduce the number of lens elements required.
Cons:1. Specific Application: Due to its specialized properties, this lens may not be suitable for all types of applications. It might be overkill for general-purpose use, leading to potential over-spending.
2. Limited Supplier: As it's a specific product from Coherent, it may not be easily available from other suppliers, potentially limiting options for price comparison and availability.
3. High Cost: Calcium Fluoride lenses are generally more expensive than other types of lenses due to the cost of the materials and the specialized manufacturing process.
Conclusion:The Coherent 34-3517-000 25.4mm Diameter Calcium Fluoride Plano Convex Lens (PCX 75mm Focal) is a high-quality lens suitable for applications requiring a large aperture, high magnification, and excellent optical properties. However, its specificity in terms of application and high cost may make it a less ideal choice for general-purpose use or for those on a tight budget.
Recommendation:If you are in need of a lens for a specific application that requires high-quality optics, a large aperture, and high magnification, this lens could be a good fit. However, it is recommended to compare prices and consider alternative options to ensure you are getting the best value for your money. If general-purpose use is your primary concern, you might want to consider less expensive options that are widely available from various suppliers.
