New infrared lens product launch

New Product Launch | UltraOpto Infrared Lens: The Core Choice for Infrared Optical Path Control

UltraOpto newly launches laser-grade infrared lenses, which serve as the core optical path control components in infrared optical systems. Specifically optimized for mid- to far-infrared bands above 2μm, they feature comprehensive upgrades in substrate, precision, and performance, perfectly adapting to diverse high-end scenarios such as industrial lasers, infrared imaging, and precision detection!

Selected from four high-end infrared-specific substrates: germanium (Ge), zinc selenide (ZnSe), silicon (Si), and zinc sulfide (ZnS), they precisely cover the full infrared band of 1.2-22μm. Each substrate achieves high transmittance and low absorption in its adapted band without infrared photodarkening. Among them, the ZnSe substrate has a transmittance of >99% in the 10.6μm CO₂ laser band, and the Ge substrate has a transmittance of over 95% in the long-wave infrared band, which can meet different infrared application needs as required.

Manufactured in accordance with national standard laser-grade precision processing standards, they feature precise diameter/curvature radius tolerances, surface accuracy of ≤λ/10@633nm, central deviation of ≤3arcmin, and accurate focal length calibration, effectively suppressing spherical aberration and image aberration. Optional infrared-specific anti-reflection coatings or broadband anti-reflection coatings are available, with post-coating band reflectivity <1%. Germanium/silicon substrates can be coated with diamond-like protective films, achieving both excellent wear resistance and light transmittance.

The product boasts strong thermal stability and environmental tolerance. ZnSe/Si substrates have low thermal distortion coefficients, which can effectively suppress the thermal lens effect under high-power lasers and are compatible with stable output of kW-level infrared lasers. Each substrate has excellent mechanical properties, being impact-resistant and scratch-resistant, and can adapt to various working environments such as wide temperature ranges, complex outdoor conditions, and harsh industrial settings.

It covers mainstream structures such as plano-convex, biconvex, plano-concave, and meniscus lenses. Meniscus lenses can efficiently correct aberrations and shorten the optical path, adapting to different optical path design requirements. At the same time, it supports full-dimensional personalized customization of substrate selection, size specifications, focal length accuracy, and coating processes, providing one-stop matching for the optical path control requirements of various infrared optical systems.

It perfectly adapts to high-end scientific research and industrial scenarios such as infrared laser cutting/welding/micromachining, infrared thermal imaging/night vision/temperature measurement, gas leakage detection, Fourier transform infrared spectrometers, as well as national defense remote sensing and quantum optics experiments, providing high-precision, low-loss, and highly stable professional optical path solutions for infrared optical applications!
