Semrock has launched the VersaChrome Edge range of tunable long- and short-pass filters. The new filters offer what the company says is virtually unlimited spectral flexibility for fluorescence microscopy, hyperspectral imaging, spectroscopy applications, as well as for filter prototyping.
The three new families of filters are designed to work together to create the equivalent of a single passband filter in the visible or near infrared. This allows researchers and instrument designers to not only create the bandpass they need, but also fine-tune edge positions and passband width to maximise brightness and contrast in real time within their measurement setup.
The ability to optimise the filter's spectral characteristics at the point of measurement has the potential to improve system performance and adapt rapidly to new fluorophores, as well as reduce the time needed to identify the optimal bandpass filter shape for a given application.
