Overview of Collimator Systems
Collimator Systems are optical assemblies designed to convert divergent light from a source or fiber into a parallel beam, or to efficiently focus a collimated beam into a small target or fiber core. On FindLight, Collimator Systems span free-space and fiber-coupled configurations for R&D labs, optical test benches, and OEM integration in photonics instruments.
Typical Specifications and Architectures
Most Collimator Systems are built around singlet, doublet, or aspheric lenses, often mounted in adjustable housings. Key parameters include:
- Wavelength range: UV (200–400 nm), visible (400–700 nm), NIR (700–1700 nm), and telecom bands such as 1310 nm and 1550 nm.
- Aperture and clear diameter: Determines beam diameter and maximum input NA.
- Numerical aperture (NA): Matching NA to the fiber or source is critical for low-loss coupling.
- Beam divergence / collimation quality: Specified as full-angle divergence or M² for laser beams.
- Working distance and focal length: Affects mechanical layout and achievable spot size at the target.
- Coatings: AR coatings optimized for single or multiple wavelength bands to minimize reflection losses.
- Fiber interface (if applicable): Connector type (FC/PC, FC/APC, SMA, etc.) and supported fiber type (SM, MM, PM).
Many Collimator Systems include focusing or tip-tilt adjustment, allowing alignment of the collimated beam relative to the mechanical axis. Some assemblies support interchangeable optics to adapt beam size or wavelength coverage.
Use Cases for Collimator Systems
Common applications include laser beam delivery, free-space to fiber coupling, optical metrology, interferometry, LIDAR test setups, and coupling light into spectrometers or detectors. Collimator Systems are also used in alignment telescopes, illumination modules, and prototype optical communication links.
Buyer Guidance on FindLight
When selecting Collimator Systems, compare wavelength range, NA, beam diameter, and mechanical interface against your source and downstream optics. Verify coating bandwidth, connector type, and adjustment features for your alignment tolerances. On FindLight you can review detailed datasheets for multiple Collimator Systems, shortlist suitable models, and request quotes from suppliers directly. No registration is required to contact vendors, enabling rapid sourcing and technical comparison for your optical design or experimental setup.
