Components
Overview
Presented below is a compilation of smaller components that have been completed as side projects alongside our primary product development. These projects have arisen either in response to specific customer demands or as essential elements required for our main instruments, but not readily available from commercial suppliers. Please feel free to assess their relevance to your research application and inform us if we can help.
Electrical probes
Most test and measurement probes with magnetic bases are able to provide micrometer-level alignment, but they are often relatively large. It became evident to Open Instruments that excessively high alignment precision is typically unnecessary, and prioritizing compactness and cost-effectiveness holds greater significance. As a response to this, we developed a compact magnetic base probe featuring spring-loaded voltage and current contact pins, as shown here. Vertical probe adjustment is accomplished using a micrometer adjuster; horizontal alignment is performed by manually translating the unit. SMA connectors ensure a dependable and detachable connection to a source-measure unit (SMU). Feel free to contact us if a modified version is of interest to you.
Pyroelectric detector
Pyroelectric detectors can serve as excellent spectral references in optical lock-in experiments. Detectors are available that display an extremely flat spectral response from the ultraviolet (UV) to infrared (IR). We required a unit featuring analogue output and the capability to accommodate chopping frequencies of up to 1 kHz. While this project is work in progress, we encourage you to reach out to us if it aligns with the needs of your research endeavours.
