Achromatic Beam Expanders
SURREY, England, Sept. 13, 2013 — 
Optical Surfaces Ltd. has released achromatic beam expanders with off-axis mirrors to provide unobstructed output and efficient transmission for applications in high-power lasers, laser scanning, interferometry, lidar systems and remote sensing.
The devices increase the diameter of a collimated input beam to a larger collimated output beam to form a small spot at some distance from the laser, or to extend the collimation range for illumination, or to align distant objects.
Available in 5×, 10×, 15× and 20× fixed magnifications, or in customer-specified fixed or variable magnifications, the devices can operate from the UV to the far-IR without adjustment and offer better than λ/5 surface accuracy. They are supplied in aluminum housing, can be fixed to an optical table and include alignment aids to ensure correct beam pointing.

Glossary
- laser scanning
- Laser scanning is a technology used to create precise digital representations of physical objects or environments by capturing their surface geometry and appearance. It involves directing a laser beam over the object or scene and measuring the distance to points on the surface by analyzing the time it takes for the laser pulses to return to the scanner.
The process typically involves the following steps:
Laser emission: A laser scanner emits a laser beam directed towards the object or...
- lidar
- Lidar, short for light detection and ranging, is a remote sensing technology that uses laser light to measure distances and generate precise, three-dimensional information about the shape and characteristics of objects and surfaces. Lidar systems typically consist of a laser scanner, a GPS receiver, and an inertial measurement unit (IMU), all integrated into a single system.
Here is how lidar works:
Laser emission: A laser emits laser pulses, often in the form of rapid and repetitive laser...
- remote sensing
- Remote sensing is a method of data collection and observation where information about objects, areas, or phenomena on Earth's surface is gathered from a distance, typically using sensors onboard satellites, aircraft, drones, or other platforms. This technique enables the monitoring and analysis of Earth's surface and atmosphere without direct physical contact.
Remote sensing systems capture electromagnetic radiation (such as visible light, infrared, microwave, or radio waves) reflected or...
