What Is A Microscope Objective?
What is a Microscope objective
A microscope objective consists of a tube, with its specifications written on it. It also has a single lens or multiple lenses, depending on what the objective is designed for. The objective may or may not include a mirror. The purpose of the objective is to gather together Light while focusing it on a specific spot in order to magnify the sample that is being studied.
Strength of an objective
Microscopes come in different strengths. The objectives do as well. The strengths of magnification that the objective offers have three to four strengths. Compound microscope strengths are usually in powers of 4x, 10x, 40x, and 100x. Microscope Objectives can be custom made to fit common specifications. They can also be custom made to interchange between several microscopes.
Microscope objective specifications
Microscope objective have markings on the casings that identifies the properties of that individual objective. This markings are very easy to read, yet are very important. There are common engravings of the specifications that are necessary for the determination of proper use for the objective. Manufactures can offer a wide range of designs for microscope objectives. These different designs are made to meet the performance demands needed to achieve specialized image methods.
Objectives are used in specific group of tube lenses and are designed that way. The tube lenses or oculars are carefully placed to aid in the removal of remaining optical errors that may occur. A numerical aperture, part of the objective, is a critical value that determines the light gathering power. It also determines the resolution power and depth of the objective field.
