◆Focal length: ≤20mm ◆Various AR coatings across UV-IR ◆Optics can be mounted on the front connector
● All lenses come with AR coating. Coupling efficiency ≤ 80% ● Converts radial output from optical fibers into parallel light with high stability ● Operates as a fiber coupler with incident light from the reverse direction ● Ideal for guiding Gaussian beams into single-mode and polarization-maintaining fibers ● For multi-mode collimation, compatibility will be confirmed based on fiber specifications and radiation characteristics ■ Lens Type for Collimators The coupling lenses from S+K are corrected for spherical aberration, leading to diffraction-limited performance in focusing and collimation. Three types of lenses with different characteristics are available for selection. - Aspheric: Aspherical lenses are designed for single-wavelength applications and correct spherical aberration. This lens type is also suitable for UHV (ultra-high vacuum) applications. - Manacromat: Designed for single-wavelength coupling/collimating, corrected for spherical aberration. - Apochromat: Optimized for multi-wavelength coupling/collimating by minimizing focal shift due to chromatic aberration in the wavelength range of 400nm to 660nm.

basic information
■Explanation of the coupling axis The standard specification of the coupler/collimator provided by S+K features an FC/APC connector with a pre-angled coupling axis. This specification is standardized based on the company's many years of expertise and minimizes the reduction in coupling ratio and adverse effects on the collimated light profile. ■Elimination of the impact on beam profile using the pre-angled coupling axis The APC connector from S+K is designed with a coupling axis that corrects beam deflection, ensuring that the incident beam passes through the center of the lens. This minimizes aberrations caused by the beam path. Schafter + Kirchhoff GmbH is a long-established optical design manufacturer in Hamburg, Germany, with a history of 60 years. After classical lens design and custom manufacturing of optical components, the company has shifted to its current business model, which includes PM fiber-related products, line lasers, and line scan cameras. As evidenced by its long-standing track record, the company's products are characterized by excellent optical and mechanical precision. Custom products beyond the listed items are also available.
