Features AR Coated for the 650 - 1050 nm Range Ø5 mm, Ø6 mm, Ø6.35 mm, Ø8 mm, Ø1/2", Ø1", or Ø2" Mounted Positive Visible Achromatic Doublets Engraved Threaded Housing on Lenses Ø1/2" and Larger Includes Part Number, Focal Length, and Coating Housing Enables Easy Integration into Thorlabs' Optomechanics Focal Lengths Available: 7.5 mm to 1000 mm Thorlabs' most popular cemented near IR achromatic doublets are available pre-mounted in engraved threaded mounts, making it easy to incorporate these optics into your setup. Choose from 7 diameters: Ø5 mm, Ø6 mm, Ø6.35 mm, Ø8 mm, Ø1/2", Ø1", or Ø2". Please see our Near IR Achromatic Doublets to purchase these lenses unmounted. The engraving on mounts 1/2" or larger in diameter clearly indicates the part number, focal length, and antireflection coating deposited onto the surface. The engraved arrow indicates the direction of light propagation to collimate a point source, and an infinity symbol denotes that this lens has an infinite conjugate ratio (i.e., if a diverging light source is placed one focal length away from the flat side of the lens, the light rays emerging from the curved side will be collimated). Mounts smaller than Ø1/2" are engraved with the part number only. These achromatic doublets, which are designed for use in the near IR spectral region (650 - 1050 nm), are optimized at infinite conjugate ratios. The design wavelengths are 706.5 nm, 855.0 nm, and 1015 nm.
