How to make abeamexpander

UniBET series beam expanders are developed for higher power (>100w) CO2 laser without water cool. It has a consistent outer dimension and connecting thread M30x1.

Motorized Zoom Beam Expander accounts for the short-fall of fixed beam expander by allowing the user to tune automatically to the required magnification factor, depending on various processes that is required. These beam expanders are also designed for high power applications where magnification adjustments may be required. The concept of zoom beam expander works on the internal translation stages and focusing mechanisms to adjust and account for the changes in magnification continuously. It also takes laser divergence into consideration and performs relative adjustments without affecting the overall housing length.

This jewelry cabinet is built with a full length mirror, large inside storage space and storage shelves on the back, making full use of the limited space. And the inside space is divided into lots of storage partitions with hooks, slots and more, which helps you organize jewelry and cosmetics well. The base is 360° rotatable so you don't need to be worried about taking items on the back storage shelves. More importantly, the mirror inside the cabinet is equipped with LED lighting that features 3 adjustable colors. And the folding acrylic table is convenient to placing makeup tools.

It’s important to note that laser safety should always be a top priority when working with lasers and laser beam expanders. Always wear appropriate protective eyewear and follow all safety guidelines and regulations.

Check the beam profile: Use a beam profiler or other measuring tool to check the spatial profile and divergence of the expanded beam. Adjust the beam expander as necessary to achieve the desired beam quality.

Beam expander in laser system development is utilized for calibrating various elements. The diameter of the laser beam at the laser system output is adapted to the required diameter at the input of the objective lens. The beam expander is also primarily used in laser-material processes. Fixed beam expanders are also designed for specific beam expansion applications such as laser engraving. They also feature anti-reflection coatings and high transmissivity to maximize the efficiency of the beam expansion and reduce losses. The disadvantage lies in the fixed magnification factor and applications that require tuning of the output beam size are unable to perform.

Beamdivergence calculator

A typical laser beam expander consists of two lenses placed a certain distance apart, with the distance between the lenses being equal to the sum of their focal lengths. The first lens diverges the laser beam to a larger diameter, and the second lens then collimates the enlarged beam to be parallel. The amount of expansion is determined by the ratio of the focal lengths of the two lenses.

Connect the laser: Connect the laser source to the input port of the beam expander. Ensure that the laser is properly focused and aligned.

Set up the laser beam expander: Mount the laser beam expander onto a stable platform or optical bench. Make sure the input and output ports are properly aligned and secured.

Zoom Beam Expander accounts for the short-fall of fixed beam expander by allowing the user to tune manually to the required magnification factor, depending on various processes that is required. These beam expanders are also designed for high power applications where magnification adjustments may be required. The concept of zoom beam expander works on the internal translation stages and focusing mechanisms to adjust and account for the changes in magnification continuously. It also takes laser divergence into consideration and performs relative adjustments without affecting the overall housing length.

A laser beam expander is an optical device used to increase the diameter of a laser beam. The purpose of a beam expander is to reduce the divergence of the laser beam, which is the tendency of the beam to spread out as it travels. By increasing the diameter of the beam, the beam expander reduces the divergence, allowing the beam to travel further without spreading out too much.
