How To Focus A Barlow Lens. This causes the light to spread out, effectively lengthening the telescope’s focal length and increasing the image’s magnification. A barlow lens is a device you can use in a telescope before an eyepiece to increase the magnification you would normally get. They do this by decreasing. One end of the tube goes into the drawtube of the focuser. The barlow is a distance ‘d’ inside the primary focus and ‘s’ inside the secondary focus. There are three things that determine this (figure 3): A barlow lens uses a negative lens element to diverge the incoming light before it reaches the primary mirror or lens of the telescope. An eyepiece (or camera) goes into the other end (see figure 2). A barlow is never the last element in the optical train and what it does is to extend further outwards the cone of light from the part of the optical train that is before it, so that what comes after, typically the eyepiece or the camera sensor. Most barlows come in a configuration in which the lens is mounted in a tube with a 1.25” or 2” barrel. A barlow lens is a diverging lens that increases the effective focal length of the optical system. In simple terms, introducing a barlow lens into the light path of any type of telescope increases the effective focal length, resulting in an increase in magnification. Barlow lenses are optical elements that increase the magnification of your telescope.
