This 400nm + Infrared dual bandpass filter is a glass-based, precision
optical coating lens designed for optical instruments and imaging systems.
It selectively transmits short-wavelength light around 400 nm together
with a defined infrared band, while effectively blocking
the unwanted visible spectrum in between.
• Stable spectral performance with multi-layer dielectric coating
• Advanced optical thin-film coating for high durability and long-term stability
• Optional round or square formats
