Description of Meade Series 4000 2x Apochromatic Barlow, 1.25" Mount
The most advanced Barlow lens yet developed for commercial telescopes, the Meade #140 2x Apochromatic Barlow includes a 3-element, air-spaced telenegative lens unmatched in image resolution, contrast, and color correction. Used with any telescope, refractor, reflector, or Schmidt-Cassegrain equipped with a focuser accepting standard 1.25" barrel-diameter eyepieces, the #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 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 availableTelescope Accessories
