适用于各种波长的可变扩束器

无限可调的扩束器可确保符合激光材料加工中所需的高精度要求。

扩束器产品系列

扩束器增加或减小激光光束的直径,可让光学系统的各类元件彼此校准。在激光输出处的激光光束的直径可根据物镜输入端所需的直径进行调整。扩束器主要用于激光材料加工。所有扩束器可与业纳的F-theta物镜集成至各种波束制导系统中。

1x-4x和2x-10x扩束器适用的激光波长为355、532和1030至1080 纳米。扩展的缩放范围使得10倍扩束成为可能。所有型号均可从最小系数无限扩展至最大系数。扩展和分散是分开调整的。这意味着扩束器可对整个光学系统进行聚焦校正。

扩束器结构非常坚实紧凑。镜片元件在更改设置的过程中不会发生旋转。这将确保极高的光束稳定性。扩束器采用衍射极限的设计:激光光束的直径仅受光的​​衍射的限制。缩放和聚焦刻度雕刻在扩束器的表面,因此可快速轻松地进行手动调节。

我们的扩束器得以进一步改进,更加精准和耐用

BEX 1x-4x steadfast的特点是新型的机械设计:线性制导移动光学元件。这减少了机械制造公差的影响,在改变放大倍率和/或发散时增加了光束方向的稳定性。扩束器实现小于1毫弧度的高辐射方向稳定性。

新设计的扩束器亦可用于锁定设置。这最大限度地减少了系统上的振动或加速度等的影响。此外,BEX 1x-4x steadfast易于安全处理,可将安装时间降至最低。

Variable Beam Expander - manual adjustment

Beam Expander 1x-8x - High Power Systems

The beam expander 1x-8x is part of the SilverlineTM high-power lens series and is designed for laser applications in wavelength ranges of 355 or 1030–1080 nanometers.

The optical system of the objective lens is designed in such a way that a diffraction-limited image quality is achieved across the entire expansion range. The optimized coatings ensure the highest transmission and minimal thermal effects in wavelength ranges of 355 and 1030–1080 nanometers. The use of full quartz guarantees a high damage threshold, so the lenses can withstand even high-power laser applications.

The innovative frame concept means that the construction of the beam expanders is extremely compact and robust. The lenses are ideally suited to the F-theta objective lenses in the SilverlineTM series. They are used in the production of microstructures, markings and inscription in different materials.

Beam Expander 1x-4x Steadfast - Very Robust Fused Silica Systems

The BEX 1x-4x Steadfast boasts an innovative mechanical design: The moving optical components are guided stably in a straight line. This reduces the influence of mechanical manufacturing tolerances and increases the beam stability when changing the magnification and/or divergence. The beam expander achieves a high beam stability of less than one milliradian.

It is also possible to lock the settings on the newly designed beam expander. That minimizes influences such as vibrations and accelerations on the system. Moreover, the BEX 1x-4x Steadfast is easy and safe to use, reducing set-up times to a minimum.

扩束器产品系列

The variable beam expanders 1x-4x for wavelengths of 355 nm, 532 nm and 1030–1080 nm offer high image quality along with their very compact length. All versions can be adjusted continuously between 1 and 4 times the expansion factor. The larger the expanded beam, the smaller the structures the F-Theta lens can generate.

A focusing ring enables targeted adjustment of the laser beam divergence and therefore compensation of the focal length tolerances in the overall system. It is also possible to change the position of the image plane according to the scanning system.

With their optimized construction design, the beam expanders are extremely robust and compact so the lenses do not rotate during a set-up change. That improves beam stability. The beam expanders have a diffusion-limited design and are tempered for the respective application wavelengths of 355 nm, 532 nm or 1030–1080 nm. The settings can be adjusted using the zoom and focus scales engraved directly onto the beam expander.

All the beam expanders are suitable for use in different beam guidance systems with Jenoptik's F-Theta objective lenses.

Beam Expander 2x-10x - Large Magnification Range

The variable beam expanders for wavelengths of 355 nm, 532 nm and 1030–1080 nm have a particularly large zoom range. All versions can be adjusted continuously between 2 and 10 times the expansion factor.

These beam expanders were specifically designed for applications where greatly expanded beam diameters are beneficial. The larger the expanded beam, the smaller the structures the F-Theta lens can generate.

Variable Beam Expander - motorized adjustment

Beam Expander 1x-8x Motorized - Automated Configuration Setting with Smart Beam Expander

New motorized beam expander 1x-8x simplifies production steps in laser material processing

The motorized beam expander 1x-8x marks a move by Jenoptik to adapt its portfolio to industry market requirements and to focus on the critical parameters of time, quality, and ease of handling. The beam expansion can be continuously adjusted from 1x to 8x using software commands.

The optimal spot size is adjustable during the running process. The divergence of the laser beam can be precisely adjusted to achieve tolerance compensation in the entire system, for example to compensate for thermal effects. Controlling the divergence also makes it possible to change the position of the working plane, for instance for 3D processing.

The lenses do not rotate while the laser beam is reduced or increased in size but are moved within a linear guide, resulting in excellent beam stability and constantly high quality. These features also reduce set-up time and increase the efficiency in production.

The motorized beam expander is a perfect match for Jenoptik's F-theta lenses in the SilverlineTM series and can be used in a large number of beam guidance systems. Thanks to the appropriate software interfaces, the new motorized beam expander can be easily integrated into any laser material processing system.
