The 9848 Optical Delay Line Mirror Mount is an easy-to-use, versatile fixture for creating an optical delay line. It has two orthogonal surfaces for mounting standard mirrors, allowing an input optical beam to be reflected back, parallel to itself. This low-cost mount simplifies the assembly of an optical delay line by virtually eliminating the time-consuming task of mirror alignment, owing to the precision orthogonal surfaces (30 arc sec., identifiable by the hatched pattern). Notwithstanding, the 9848 is a significantly less expensive alternative to the wavelength-bound retroreflector. Retroreflectors exist typically as solid glass (prohibitive for most delay lines) or with metallic coating, which have substantial losses. A key advantage of this mount is that you can use any mirror coating, including dielectric. The 9848 is versatile because it holds various sizes, shapes and thicknesses of mirrors and allows variable spacing between the input and output beams up to 2 in. (50 mm). Guide lines set at 0.5 in. (12.7 mm) increments are provided to assist in setting beam spacing. The 9848 can be mounted directly to a translation stage via a centralized hole counterbored for 1/4-20 (M6) cap head screws or pedestal-post mounted on a SR- or PS-series post.
9848光学延迟线镜安装是一个易于使用,多功能夹具创建光学延迟线。它有两个正交的表面用于安装标准镜子,允许输入光束被反射回来,与自身平行。这种低成本的安装简化了光学延迟线的组装,由于精确的正交表面(30弧秒,可由阴影模式识别),实际上消除了耗时的镜像校准任务。尽管如此,相对于波长约束反射器,9848要便宜得多。反射镜通常以固体玻璃的形式存在(对于大多数延迟线来说是禁止使用的),或者带有金属镀层,这样会造成很大的损失。这种安装的一个关键优点是,您可以使用任何镜像涂层,包括介质。9848是多功能的,因为它有各种大小,形状和厚度的镜子,并允许可变间距之间的输入和输出光束多达2英寸。(50毫米)。指导线设置在0.5英寸。(12.7 mm)增量用于帮助设置梁间距。9848可以通过1/4-20 (M6)帽头螺钉或安装在SR-或ps -系列柱上的基座柱上的中心孔钻直接安装到转换台上。
