Denoted by a number (such as 0.17mm) the cover slip thickness is labeled on the objective to note the type of cover slip that should be used. A cover slip changes the way light is refracted from the specimen. Therefore, it is important to ensure that the right cover slip is used in order to produce a good quality image. Zero(0) denotes no coverslip to use. Dash(-) denotes use of coverslip or no cover slip, it does not matter.

A 3D body can be rotated about three orthogonal axes, as shown in Figure 3.8. Borrowing aviation terminology, these rotations will be referred to as yaw, pitch, and roll: A yaw is a counterclockwise rotation of about the -axis. The rotation matrix is given by (3.39) Note that the upper left entries of form a 2D rotation applied to the and coordinates, whereas the coordinate remains constant. A pitch is a counterclockwise rotation of about the -axis. The rotation matrix is given by (3.40) A roll is a counterclockwise rotation of about the -axis. The rotation matrix is given by (3.41) Each rotation matrix is a simple extension of the 2D rotation matrix, (3.31). For example, the yaw matrix, , essentially performs a 2D rotation with respect to the and coordinates while leaving the coordinate unchanged. Thus, the third row and third column of look like part of the identity matrix, while the upper right portion of looks like the 2D rotation matrix. The yaw, pitch, and roll rotations can be used to place a 3D body in any orientation. A single rotation matrix can be formed by multiplying the yaw, pitch, and roll rotation matrices to obtain (3.42) It is important to note that performs the roll first, then the pitch, and finally the yaw. If the order of these operations is changed, a different rotation matrix would result. Be careful when interpreting the rotations. Consider the final rotation, a yaw by . Imagine sitting inside of a robot that looks like an aircraft. If , then the yaw turns the plane in a way that feels like turning a car to the left. However, for arbitrary values of and , the final rotation axis will not be vertically aligned with the aircraft because the aircraft is left in an unusual orientation before is applied.

It is an angle of incidence. It is the most important parameter of a microscope. NA measures its ability to gather light. It’s an important factor to determine resolution, depth of focus, and the brightness of images. Objectives with a larger NA gather a wider range of light, resulting in brighter, higher resolution images.

The objective depth of field is the axial range, which enables you to focus an objective without any considerable change in image sharpness. This value varies radically from low to high numerical aperture objectives; it usually decreases as the numerical aperture increases.

The higher the NA, the smaller the distance between two objects. As we mentioned previously, choosing the right NA for your application is crucial in determining the resolution of your microscope system.

Optical correction such as achromatic, apochromatic, plan and semi-plan are often denoted on the objective in order to show the design of the objective. Plan and semi-plan objectives correct for field curvature. Field curvature often results in blurred images on the periphery and correction for this helps produce good quality images. Whereas plan objectives correct better, allowing for better display (over 80 per cent) of field flat, semi-plain objectives produce about 65 per cent.

The resolution of the microscope objective determines the smallest distance between two objects that can be observed. It is directly proportional to the illumination wavelength of light and inversely proportional to the NA.

On the objective, this is usually denoted by an X next to a numeric value (100X, 10X etc). On the other hand, objectives will also have a colored band around the circumference of the objective that indicates the magnification of the objective. For instance, a yellow band around the objectives (lower part of the objective) indicates that it is a 10x objective.

Each objective and eyepiece has a specific purpose or function. Objective lenses magnify the image that enters the objective and bring it to a sharp, clear focus. Eyepieces take the light that has been focused by the objective lenses and magnify it further so that you can see it. The magnification power is measured by objective magnification multiplied by eyepiece magnification.

In a finite conjugate design, the objective focuses light from the object into the focal plane of the eyepiece. An infinite corrected objective collects light from the object and forms a parallel beam that passes through a tube lens.  The advantage of this design is that additional optical elements, such as polarizers, filters, and wave-plates, can be placed in between the tube lens and the objective without interfering with the focusing of the beam. The infinite conjugate design is often used in fluorescence microscopes, which rely on filters.
