Did You Know?

The word "collimate" derives its origin from the Latin verb collimare, which is a misreading of collineare, meaning "to direct in a straight line’’. Going back to the history, it was Henry Kater who, in 1825, invented the world’s first collimator, which had applications in practical astronomy. Optical collimators are now widely used as instruments for calibration and alignment in gunsights, fiber optics and various telescopic devices. The primary function of a collimator is to make light beams parallel, so that the spread is minimized upon propagation.

Frequently Asked Questions

A fiber collimator contains an objective lens that can focus the beam to a small spot or expand it. When the source is placed at the focal point of the lens, the lens will increase the diameter of the beam and the rays will come out parallel. On the other hand, if the incoming beam is already collimated, then the lens will focus it at the focal point.

Fiber Optic Collimators: Precision Beam Control for Fiber-Coupled Systems

Fiber optic collimators are key components in photonics systems that transform the divergent light emerging from an optical fiber into a parallel (collimated) beam. These versatile devices are widely used in fiber optic communications, laser systems, spectroscopy, and sensing applications. On FindLight, you can explore a broad selection of high-precision fiber collimators designed for single-mode, multi-mode, and polarization-maintaining fibers, from trusted global suppliers.

What Are Fiber Optic Collimators?

A fiber collimator typically consists of a fiber connector aligned to a precision lens—often an aspheric or GRIN (graded-index) lens—housed within a rigid metal barrel. The lens focuses the diverging light emitted from the fiber core into a parallel beam, allowing for efficient free-space propagation, optical coupling, or interaction with other components.

Collimators are crucial when integrating fiber optics with bulk optics, such as mirrors, beam splitters, or interferometers. They’re also essential in minimizing signal loss and preserving beam quality in systems requiring free-space transmission over short distances.

Key Features and Benefits

  1. Highly Collimated Output: Delivers parallel light beams with minimal divergence, essential for accurate optical alignment.

  2. Low Insertion and Return Loss: Designed for optimal optical performance, ensuring efficient light coupling and minimal signal reflection.

  3. Multiple Wavelength Options: Available for telecom wavelengths (1310 nm, 1550 nm), visible light, and even mid-IR applications.

  4. Customizable Design: Offered in various lens types, working distances, beam diameters, and connector formats (FC, SC, LC, SMA, and more).

  5. Robust Construction: Housed in precision-machined barrels for long-term reliability in laboratory and industrial settings.

Common Applications

Fiber optic collimators are used in a wide variety of optical systems, including:

  • Fiber-to-free-space coupling

  • Laser beam delivery systems

  • Wavelength division multiplexing (WDM)

  • Fiber optic sensing

  • Optical alignment and testing

  • Interferometry and spectroscopy

They are often employed as input/output ports for circulators, isolators, and other bulk optic devices requiring high alignment precision.

How to Choose the Right Collimator

Selecting the right fiber collimator depends on:

  • Wavelength Range: Ensure the lens and coating are optimized for your operating wavelength.

  • Beam Diameter: Choose a size based on how tightly or broadly you need to collimate the beam.

  • Working Distance: The optimal distance over which the beam remains collimated.

  • Connector Type: Match with your existing fiber connector (e.g., FC/APC for low back-reflection).

  • Fiber Type: Available for single-mode, multi-mode, and PM fiber configurations.

At FindLight, you can filter by these specifications to quickly identify the most suitable product.
