There is no objective lens for reading the data.

The objective lens of a microscope is the one at the bottom near the sample.

Reflected in the mirror is the image from the second objective lens (C).

Its job is to enlarge the central part of an image obtained by the objective lens.

He switched the objective lens, adjusted the focus, and off we went through several more slides.

See the full list of 3 objective lens videos in this playlist.

The first portrait objective lenses were rather small and had a diameter of 2.6 cm.

They have objective lenses that are approximately in line with the eyepieces.

After the electrons have left the sample they pass through the electromagnetic objective lens.

So, with two objective lenses one can collect from every direction (solid angle ).

The objective lens or mirror collects light and brings it to focus creating an image.

Starting with an eye-piece of 10X, he rotated the objective lenses.

It represents the distance at which the mirror or objective lens will cause light to converge on a single point.

She moves the slide around under the objective lens as Eise looks on, somewhat interested.

The objective lenses required for cathodoluminescence must have long working distances, so choice is often limited and prices high.

This would denote 10 times magnification with a 50 mm objective lens.

Microscopes were first developed with just two lenses: an objective lens and an eyepiece.

A specimen is placed above the magnetic objective lens, which produces a magnified image.

The objective lens of the periscope is concealed in a roof ventilator.

Light from an origin point O is collimated (made parallel) by a high quality objective lens.

Binoculars have a focusing arrangement which changes the distance between ocular and objective lenses.

Light of the excitation wavelength is focused on the specimen through the objective lens.

In the ideal case each objective lens can collect light from a solid angle of .

The worst that can happen is for the front objective lens to break, which usually occurs when the telescope is dropped.

They had 100mm objective lenses, and were fitted with 45 degree eyepieces for more convenient use while on a mount.
