Wayho LCTF-N20
Liquid crystal tunable optical filterLCTF control software · USB · C/C++ SDKLCTF-N20 is a tunable filter that selects wavelengths using the electro-optical properties of liquid crystals. Its 450–950 nm spectral range, electronic control and modular optics enable hyperspectral imaging systems to be built with lenses and sensors.
Select the wavelength. Separate optical data.
Electronic wavelength selection
Define start and end wavelengths, step intervals and scanning times in the control software.
Modular optics
Combine the filter with suitable lens and sensor components to suit your application.
Software integration
USB control and a C/C++-compatible SDK support custom imaging system development.
Optical planning with model-specific values
FWHM for this model is listed as 10 nm at 550 nm. Spectral range, bandwidth and response time should be evaluated together.
Applications and use cases
- Hyperspectral system development
