Alignment Techniques Using Piezo Stages
Piezo stages are often used to perform raster scans in alignment set-ups aimed at finding optical power peaks. Flexure-based piezo stages have the advantage of frictionless scanning which enables higher scanning speeds without wear. The nPoint LC.400 controllers and GUI offer a variety of capabilities aimed at reducing the time that it is required to […]
How Piezo Stages React to Temperature Variation
Qualitative analysis Flexure-based piezo stages are essentially blocks of metal with flexure patterns that create a moving platform suspended from static frame via flexures. The sketch below shows a simplified flexure stage that moves in one direction when the piezo expands or contracts. A capacitive sensor is used as the feedback sensor and a preload […]
Piezo Stage Load vs. Settling Time
To maximize the capabilities of piezo stages, it is important to understand how different factors contribute to the performance of the system. For many applications, the resonant frequency and settling time of a stage are of primary interest. In this blogpost we explore how the resonant frequency and settling time are affected by the load […]
Choosing a Controller Interface
There are several interfaces available for the LC.400 series, each providing a unique way to interact with the nPoint controllers. First we will cover the interfaces that come with every standard LC.400 series controller, and then we will describe the optional interfaces that can be added. Standard Interfaces USB Port – All nPoint controllers are […]
