Meade Series 4000 #140 2x Apochromatic Barlow Lens (1.25") 07277-1: The most advanced Barlow lens yet developed for commercial telescopes, Meade #140 2x Apochromatic 1.25" Barlow Lens #07277-1 includes a 3-element, air-spaced telenegative lens unmatched in image resolution, contrast, and color correction.

Used with any Telescope Accessories - refractor, reflector, or Schmidt- Cassegrain - equipped with a focuser accepting standard 1.25" barrel-diameter eyepieces, Meade #140 Barlow doubles the telescope's effective focal length, thereby doubling the effective eyepiece magnification. With a diagonal mirror or prism placed between the Barlow and an eyepiece (e.g., in applications with refractors or Schmidt-Cassegrains), effective eyepiece magnification is approximately tripled. The #140 optically complements Meade Series 4000 eyepieces, while enhancing the performance of other eyepieces as well.

Mechanical components are of machined aluminum and brass. Lens diameter is 28mm; clear aperture is 26mm. The multi-coated optics of the #140 Barlow Meade 1.25 " Lens provide maximum light transmission and image contrast.

Thousands of these Meade Barlow systems are now in use by advanced amateurs worldwide. There is no finer Barlow available.
