Hot Sale Different Sizes of Doublet Optical Achromatic Lens

"When a beam of light parallel to the main optical axis passes through a convex lens and intersects at a point, this point is called the focal point. The plane passing through the focal point and perpendicular to the optical axis is called the focal plane.". There are two focal points. The focal point in the object space is called the "object focal point", and the focal plane there is called the "object focal plane"; On the contrary, the focal point in the image space is called the "image focal point", and the focal plane there is called the "image focal plane.".

Lens is the most basic optical element that constitutes the optical system of a microscope. Components such as objective lens, eyepiece, and condenser lens are composed of a single or multiple lenses. According to their different shapes, they can be divided into two categories: convex lenses (positive lenses) and concave lenses (negative lenses).
