- Kowa’s Floating Mechanism design is incorporated into all HC-VIS-SW series models to
A key characteristic of near infrared (NIR) corrected lenses
is their ability to capture clear images while maintaining
sharp focus, even when wavelengths transition between
visible light and NIR light.
Unlike standard lenses that experience focus shift due to
refractive index variations caused by wavelength changes,
Kowa’s NIR corrected lenses are engineered with specially
manufactured extra low dispersion (XD) glass. This optical
technology ensures exceptional image quality and precise
focus across a broad wavelength range, providing reliable
performance for high-precision imaging applications.
