Key Takeaways: Hyperspectral camera lenses are crucial for capturing detailed spectral information. The objective lens of SWIR cameras in this case study covers a broad band (1000-2500 nm) in a compact design. High transmittance glass suits short-wave infrared applications. Good color correction and close-to-diffraction-limit design improve image quality. Consideration of heat dissipation ensures performance in […]
Read moreKey Takeaways: A wide-angle thermal imaging lens, unlike narrow-angle lenses, captures a broad field of view for comprehensive monitoring and detection. They convert infrared radiation into visible images which show temperature variations. This is essential for surveillance, firefighting, search and rescue, industrial inspections, and environmental monitoring. Avantier’s lenses enhance situational awareness and thermal data analysis.

Read moreKey takeaways: Aspherical lenses improve optical systems by reducing aberrations and enhancing quality, especially in infrared lens design using materials like chalcogenide glass and germanium. This case study for a wide field of view and long wavelength infrared lens that initially used spherical lenses found significant benefits by switching to aspherical design, expanding the field […]
