様々な波長に向けた可変ビームエキスパンダー

無限調節が可能なビームエキスパンダーはレーザー加工に必要とされる高レベルの精度を実現します。

ビームエキスパンダー製品グループ

ビームエキスパンダーはレーザービームの径を大小させることが出来るため、光学系の様々な要素をお互いに校正することが出来ます。レーザー出力時点でのレーザービーム径は対物レンズ入力に時点で必要とされる径に適合させることが出来ます。ビームエキスパンダーは主にレーザー加工に使用されます。あらゆるビームエキスパンダーは広範囲のビーム誘導システムにおいて、Jenoptik 製Fθ対物レンズに統合することが出来ます。

1x-4x および 2x-10x ビームエキスパンダーは 355, 532 および 1030 ~ 1080 ナノメートルのレーザー波長にてご用意しています。.ズーム範囲の伸長により、最大10倍のビーム拡大が達成できます。すべてのバージョンは最小から最大のビーム拡大率で無限調節可能です。エキスパンションとビーム開きは別々に調節します。そのため、ビームエキスパンダーで光学系全体の焦点補正が出来ます。

ビームエキスパンダーは極めて堅牢な設計であり、コンパクトなハウジングを備えています。設定の変更時にもレンズ要素を回転することはありません。そのため、際立って高いビームの安定性が得られます。ビームエキスパンダーは回折限界に到達しています:レーザービームの径は光の回析によってのみ制限されます。ズーム及びフォーカスのゲージはビームエキスパンダーに刻印されているため、手動での調節も素早く簡単に行うことが出来ます。

精度と耐久性をさらに高めるため、ビームエキスパンダーはさらに発展しています

BEX 1x-4x ステッドファストの特徴はその新しい機構設計にあります:可動光学要素が直線的に動きます。そのため、倍率および/またはビーム開きの変更時の機構的な製造上の公差における影響を低減し、ビーム方向における安定性が向上されます。ビームエキスパンダーは1ミリラジアン未満の照射方向における高い安定性を達成することが出来ます。

新しく設計されたビームエキスパンダーはまた、設定のロックにも使用できます。ロックすることで、システムの振動または加速による影響を最低限に抑えることが出来ます。また、BEX 1x-4x ステッドファストの取り扱いは簡単かつ安全なので、設定時間を最低限に抑えることが出来ます。

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.

ビームエキスパンダー製品グループ

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.
