Achromatic Doublet Positive Lenses, AR Coating: 400 nm-700 nm, Unmounted — Model AD520-A

Operating wavelength 400 nm-700 nm, focal length 400.0 mm, Ø50.8 mm, substrate N-BK7/N-SF2.

Product Description

  • Small focal length shift across different wavelengths
  • High-precision design and manufacturing to meet diverse needs
  • Operating wavelength: 400 nm-700 nm (with anti-reflection coating)

The achromatic doublet lens significantly optimizes chromatic aberration and spherical aberration through composite optical materials, with optical performance far surpassing that of singlet lenses, meeting the demands of high-precision imaging and complex beam control. The LBTEK Achromatic Doublet Lenses employ a multi-wavelength optimized design, precisely matching three sets of core wavelengths for different anti-reflection coating systems: the wavelengths of 486.1 nm (F-line), 587.6 nm (d-line), and 656.3 nm (C-line) are selected for the 400-700 nm coating system; the wavelengths of 706.5 nm, 855 nm, and 1015 nm are selected for the 700-1100 nm coating system; the wavelengths of 1016 nm, 1330 nm, and 1550 nm are selected for the 1100-1650 nm coating system; the wavelengths of 488 nm, 707 nm, and 1064 nm are selected for the 400-1100 nm coating system. Multi-wavelength collaborative computation ensures that the lens's focal length shift within the design bandwidth is less than 0.5 mm, with stable performance across the entire spectrum. The LBTEK Achromatic Doublet Lenses are precisely manufactured and rigorously quality-controlled to guarantee the high-quality performance at a cost-effective price.
