Transmissive Aspherical Lens Reflective Aspherical LensCut-off linear variable filter is an interference filter whose cut-off wavelength varies linearly with physical position. Continuous gradient based on film thickness, utilizing the interference effect of light to achieve wavelength selection. Continuous and adjustable spectral filtering is achieved through a single filter, greatly simplifying system design and serving as a powerful tool for miniaturization, integration, and dynamic spectral analysis of equipment. From miniature spectrometers to multispectral imaging, from industrial sorting to scientific research equipment, its applications can be found.
Wavelength (nm) | Peak transmittance (%) | Depth of cut-off | Pass band | Linear rate of variable (nm/mm) | NOTE |
400-800 | ≥85 | ≥OD3 | Short pass | 7 | Customized be met |
400-800 | ≥85 | ≥OD3 | Long pass | 7 | |
380-850 | ≥85 | ≥OD3 | Long pass | 22.3 |
