Description
PM Fiber Optic Collimator for Fixed Working Distance
The PM Fiber Optic Collimator by Ysenser is engineered to deliver precision and reliability in optical applications. This collimator is designed to provide a fixed working distance, ensuring consistent performance across various operational environments. With a focus on precision, the collimator features a well-defined beam waist and divergence angle, making it an ideal choice for applications requiring exact beam alignment and stability. Manufactured with high-quality components, the collimator supports multiple wavelength options, including 633nm, 780nm, 850nm, 980nm, 1064nm, and 1310nm, each with a specific bandwidth tolerance. The product is optimized for minimal output loss and high return loss, ensuring efficient signal transmission and reception. The extinction ratio of ≥20dB further enhances the collimator's capability to maintain signal integrity, making it suitable for demanding optical systems. The collimator is packaged in a compact design with a standard Φ3.4mm*L14mm or Φ4.0mm*L20mm enclosure, depending on the model. Its robust construction is complemented by a range of working distances, from 100mm to 1000mm, catering to diverse application needs. The use of premium fiber types such as Nufern PM630, PM780, PM980, and Corning PM1300 ensures compatibility with a wide array of optical setups, enhancing the versatility and adaptability of the collimator in various technological fields.
