2010年6月17日 - Numerik Jena提供套件L4编码器，一个最小配置为长度测量系统，用于安装空间有限的使用。这种极其扁平的编码器，允许异常广泛的安装公差和可选机械框架中预先调准的测量模块，为用户提供用户友好安装。

              
L4编码器典型的应用领域是用于一下领域的仪器和机械，如微电子产业，XY和压电式，精密仪器及医疗系统等等。该套件是以Numerik Jena和刻度尺的，小型化和多功能EPIFLEX测量模块为基础的。该刻度尺接受反射光的扫描。                         

该Numerik Jena套件L4编码器提供高分辨率（达50 nm），高测量速度（10米/秒）和高绝对精度（每平方米1微米）。尤其值得注意的是，机械安装以后，电子信号调整是可以优化测量模块输出的。这可能导致插值误差和激活功能储备的减少。

June 17, 2010 - Numerik Jena offers the Kit L4 encoder, a minimum configuration of a length-measuring system for use in situations where installation space is limited. This extremely flat encoder allows for unusually wide mounting tolerances and a pre-alignment of the measuring module in an optional mechanical frame for user friendly installation.

Typical fields of application for the Kit L4 are instruments and machines used in the microelectronic industry, X-Y and Piezo stages, precision devices and medical systems, to name a few. The kit is based on the miniaturized and multifunctional EPIFLEX measuring module from Numerik Jena and on graduated scales. The scales are scanned in reflected light.

The Numerik Jena Kit L4 encoder offers high resolution (up to 50 nm), high measuring speed (10 m/s) and high absolute accuracy (1μm per m). It is especially noteworthy that after mechanical installation, electronic signal adjustment is possible to optimize measuring module output. This can result in a reduction of the interpolation error and activation of functional reserves.

The scale tape of the Kit L4 is available in two patented versions: a SINGLEFLEX scale tape used in more basic applications where thermal expansion behavior is the same as steel (20 micron tape with self-adhesive tape) or a DOUBLEFLEX scale tape for applications with higher accuracy requirements and measuring lengths longer than 100 mm. The DOUBLEFEX system allows for mechanical isolation of the scale tape from the tape carrier resulting in a well defined thermal behavior.

The Numerik Jena Kit L4 is available in a wide variety of frames, as well as custom options. Signal interfaces offered are TTL or 1 Vpp.
