Apochromatic Barlow Lenses
An apochromatic Barlow lens provides less or no effect of chromatic aberrations compared to much more common achromatic lenses. Here you can find all models from Levenhuk.
Magnification: 2.5x. Barrel diameter: 1.25"
Magnification: 5x. Barrel diameter: 1.25"
One quality Levenhuk Barlow lens instead of several telescope eyepieces
If you want to extend your telescope’s magnification range, but don’t want to spend money on several eyepieces, buying a telescope Barlow lens is the best solution. As you probably already know, Barlow lens is used to increase a telescope's focal length and, in turn, the magnification of any eyepiece used with it.
In some cases having just one Barlow lens is enough to obtain all useful magnifications of an optical instrument. You can buy Barlow lens with magnification of 2x, 3x, 4x and even 5x (depending on capabilities of your optical instrument), although 2x Barlow lens magnification is the most used among amateur astronomers.
If you buy telescope Barlow lens, you will get an instant increase in the power of your telescope. But remember that such an easy way of increasing magnification comes at a price. It’s a well-known fact that using a Barlow lens significantly affects image quality. Barlow lenses can be achromatic and apochromatic. Apochromatic Barlow lenses (gathered in this section) provide better correction of chromatic aberrations and, therefore, better image quality. Optical elements of these apochromatic lenses are covered with full multilayer coating. Levenhuk apochromatic Barlow lenses can be used for visual observations, as well as for astrophotography. Some Barlow lens models are threaded for optical filters; take a look at a model’s specification table for details. While you’re at it, don’t forget to check a Barlow lens barrel diameter to find out whether it is compatible with your telescope model.
