ELL6K Dual Position Optics Slider Kit Chapter 1: Introduction
Chapter 1 Introduction
The ELL6 dual position slider for SM1 optics is part of the Thorlabs series of piezoelectric resonant motor circuits
and bare modules for OEM applications. The resonant piezo design of these motors offers fast response times and
precise positioning, and are therefore particularly useful in scanning applications. These piezo motors also do not
include magnets like traditional motors, making them ideal for applications that are sensitive to electromagnetic
interference.
The high-speed digital signal processing (DSP) architecture supports a multi-drop serial communication protocol,
and a set of digital IO lines allows the user to control the movement and state manually by switching the lines high
(5V) or low (0V).
The slider features two mounting positions for SM1 optics. It can be post-mounted using our ER series cage system
rods and a CP02(/M) Cage Plate and is also compatible with 30 mm cage systems. It offers 31 mm (1.2") of travel
with 100 µm repeatability and a switching time of 180 to 270 ms. The module is powered via a 5V power connector
or via USB.
A hand-held controller is supplied with the ELL6K evaluation kit to allow manual switching between the two
positions. The unit can also be driven remotely via PC-based software, downloaded from www.thorlabs.com. A
compatible USB driver is included in the software download package.
