產品系列說明

Designed to Give Increased Resolution and Smaller Spot Sizes for NIR Wavelengths (750-1100nm)
單色光源的球面像差更小(不足2μm)
Broadband AR Coating has <1% Reflectivity Between 750–1550nm

TECHSPEC® Near-IR (NIR) Achromatic Lenses are designed to provide the smallest spot size possible for polychromatic light between 750 and 1100nm. By utilizing our NIR doublets instead of standard doublets designed for the visible, RMS spot diameter can be reduced from 43μm to 22.5μm, for example, when using polychromatic light. Spot size will be smaller when focusing monochromatic sources. Near-IR doublets also reduce spherical aberration and have superior performance when used with a monochromatic source up to 2μm in wavelength. Typical applications for these doublets include: imaging lenses for the near infrared, focusing and expanding of NIR lasers, and focusing/collimating lenses for fiber optics and NIR LEDs.
