VersaChrome Edge™ Tunable Long-wave and Short-wave pass Filters

Tunable Long Pass Filter: Angle tuning of this filter allows for adjustment of long pass edge. Passband range is ~12% of edge.

Tunable Short Pass Filter: Angle tuning of this filter allows for adjustment of short pass edge. Passband range is ~12% of edge.

Full Spectrum Blocking Filter: This filter provides high blocking over a wide spectral range.

Maximize Flexibility Within Instrument Design

By utilizing a combination of VersaChrome Edge tunable long-wave pass and short-wave pass filters, a bandpass filter as narrow as sub 5nm FWHM or as wide as 12% of the center wavelength within the visible and near-infrared wavelength ranges can be created.

Until now, customers unable to find an off-the-shelf bandpass filter to meet their needs had to choose between using a suboptimal filter or purchasing a prototype run of a custom filter specification at significant cost. With the VersaChrome Edge Tunable Filters, Semrock is offering an alternate way to create unlimited bandpass configurations. Our three families of filters (TLP, TSP, and Full Spectrum Blocking) 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 alike to not only create the bandpass they need, but also fine-tune edge positions and to maximize brightness and contrast/signal-to-noise in real time, within their instrument.

Determine which tunable edge filters and full spectrum blocking filter to select to make your own unique passband using the VersaChrome Calculator.
