The M-LCM-2 Self-Centering Lens Mount reliably centers and securely holds 3.2 to 60.3 mm diameter round optics and cylindrical objects. It is particularly useful when different-sized lenses must be interchanged while keeping the optical axis height constant. Model M-LCM-2 accommodates optics up to 50.8 mm diameter and has metric threads. It is oversized to provide easy finger access for inserting and removing optics. The optic is held by non-marring Delrin rods that have modified V-groove tips to grip the edges of thin lenses and flat shoulders for registration of thicker optics. These lens mounts are based on a familiar coaxial-ring concept designed so the mechanism is completely enclosed for ruggedness. A conveniently positioned actuator lever rotates a spring-loaded inner ring, which pivots the three optic support rods radially to provide automatic centration. LCM Series Mounts can mount on SP Series Posts for easy adjustment of vertical height and azimuth angle. Alternatively, pedestal posts provide a selection of convenient, fixed optical axis heights and direct tie-down to tables and breadboards.

该m - lc -2自定心透镜安装可靠的中心和安全的持有3.2至60.3毫米直径的圆形光学和圆柱物体。在保持光轴高度不变的情况下，当不同尺寸的透镜必须互换时，这种方法特别有用。模型M-LCM-2可容纳直径50.8 mm的光学元件，并具有公制螺纹。它是超大的，提供方便的手指访问插入和删除光学。光学是由非marring的Delrin杆持有，这些杆有改进的v型槽尖端，以抓住薄透镜的边缘和平的肩膀，以注册较厚的光学。这些镜头安装是基于一个熟悉的同轴环的概念设计，所以机构是完全封闭的强度。一个方便的定位执行机构杠杆旋转一个弹簧负载的内圈，它旋转三个光学支撑杆径向提供自动居中。LCM系列支架可安装在SP系列支架上，方便调整垂直高度和方位角。此外，基座柱提供了一个方便的选择，固定的光轴高度和直接连接到桌子和面包板。
