ABSTRACT:
An objective lens for microscope of low magnification is of a two-group structure and is composed, in the order from the object side, of a converging front lens group having a meniscus lens component convex toward the object and a converging rear lens group including a positive lens component having a stronger curvature at the image side and a biconvex lens component. The meniscus lens component in the front lens group is composed of a biconvex positive lens and a biconcave negative lens adhered together at an adhered interface convex toward the image side. The lens surface at the object side of the meniscus lens component of the front lens group is convex toward the object side and has a positive refractive power, while the lens surface at the image side of said meniscus lens component is concave toward the image side and has a negative refractive power.
