What is a Barlow Lens?
A Barlow is a negative (diverging) lens that is placed between the objective lens (or primary mirror) and the eyepiece of a microscope. It increases the effective focal length of an objective lens, thereby increasing the magnification. The idea is that 2 eyepieces and a Barlow will give you the flexibility of magnification of 4 eyepieces, and will give higher magnifications with less powerful eyepieces.
Features:
Aluminum alloy body with black anodized surface is precision machined, stable and durable for a long-time use.
2X magnification with 23.2mm interface increases the magnification of any 23.2mm eyepiece and also can provide comfortable viewing.
Easy to use： simply insert the eyepiece into Barlow lens, and then insert the Barlow lens into the microscope.
