Air-Spaced Doublets

Thorlabs selection of air-spaced doublets offer diffraction-limited spot size, superior aberration correction, and higher damage thresholds than traditional cemented doublets. Our Laser-Line Air-Spaced Doublets have been optimized for best performance at either 532 or 1064 nm. Our Air-Spaced Achromatic Doublets have been designed for use across a broad wavelength range with minimal abberations. They are available for the 240 - 410 nm, 400 - 700 nm, 650 - 1050 nm, 3 - 5 µm, or 8 - 12 µm wavelength ranges.
