IdealPhotonics' near-infrared lens is an optical imaging component optimized for the 700-1700nm near-infrared band. It employs special coatings (such as broadband anti-reflection coatings) and low-dispersion materials (such as calcium fluoride) to ensure high transmittance and image quality correction, making it suitable for night vision, semiconductor inspection, and biological tissue imaging.Parameters including near-infrared transmittance (>90%@specific bands, such as 850nm/1550nm), material dispersion characteristics (such as CaF₂ low dispersion), coating anti-reflection bandwidth (700-1700nm), aberration correction (wavefront error <λ/4), and thermal stability (temperature drift <0.01%/℃) collectively determine its image sharpness and environmental adaptability.
