The SL76.2BD Gimbal Optical Mount is a true gimbal mount for high-resolution azimuth and elevation adjustment of 3 inch (76.2 mm) diameter mirrors and beamsplitters. The fixed rotational axes intersect at the front surface of the optic, allowing simple, non-coupled rotation without translation. The gimbal design also greatly reduces beam wander and optical path-length changes. These mounts are designed for maximum clear aperture of the transmitted beam at a 45° incident angle. SL Mounts are designed for a single nominal optical diameter for positive, made-to-fit three-point mounting inside the gimbal body. The base plate can be mounted in two places which allows you to convert between right-hand and left-hand operation. SL Series Mounts are configured with a base plate and riser (if required) for a nominal 50 or 75 mm optical axis height. Riser blocks of 25 mm and 50 mm may be placed in any combination beneath the base plate to achieve any optical axis height (>75) which is a multiple of 25 mm. For continuously variable height adjustment we recommend the ECN-80 elevator base. For ten times higher positioning sensitivity this version includes BD Differential Micrometers.


SL76.2BD万向节光学支架是一个真正的万向节支架，用于3英寸(76.2 mm)直径的镜子和波束分离器的高分辨率方位角和仰角调整。固定的旋转轴相交于光学的前表面，允许简单的，不耦合的旋转没有平移。框架的设计也大大减少了光束漂移和光路长度的变化。这些支架是用于传输光束的最大光圈在45°入射角。SL支架设计成单公称光学直径，用于万向节阀体内的三点正安装。底板可以安装在两个地方，使您可以转换之间的右手和左手的操作。SL系列支架配置底座和提升管(如有需要)，标称光轴高度为50或75毫米。提升管块为25mm和50mm，可以任意组合放置在底板下方，以达到25mm倍数的任意光轴高度(>75)。对于连续可变高度的调整，我们推荐ECN-80电梯底座。对于十倍高的定位灵敏度，该版本包括BD差动测微计。
