Comparison Between Day/Night Lens and Conventional Lens (Diagram)
Without correction for the near infrared light wavelengths, the conventional lens produces focus shift and the image deteriorates due to multiple wavelength in light transmission.

Day/Night varifocals with their optical arrangement, minimizing discernible focus shift across all focal lengths from visible to near infrared light wavelengths, producing clearer images during the day and at night.

Applications
Surveillance of shops, financial institutions, office buildings, etc.
