Telecentric Lens with Focus Shift Correction
Visible - SWIR
Focus shift correction in wide wavelength band from Visible to SWIR
- Focus shift correction in wide wavelength band from Visible to SWIR
- Clear images in visible light and transmitted images in SWIR can be captured without focus adjustment
- Possible to capture differences and defects that cannot be seen in visible ray
