Where is the substage condenser on a microscope?

A microscope condenser, also called a substage condenser when it’s not above the stage (as in an inverted microscope), is defined as an optical lens which renders a divergent beam from a point source into a parallel or converging beam to illuminate an object.

What is the function of the condenser condenser lens?

A condenser is a glass lens or lens system located within or below the stage (sub-stage) on compound microscopes. Its basic function is to gather the light coming in from the illuminator and to concentrate that light into a light cone onto the specimen.

What is the purpose of the condenser on a microscope?

On upright microscopes, the condenser is located beneath the stage and serves to gather wavefronts from the microscope light source and concentrate them into a cone of light that illuminates the specimen with uniform intensity over the entire viewfield.

How do you adjust the condenser on a microscope?

Most compound light microscopes have a small knob (2) to raise and lower the condenser holder. Lower this holder so the condenser can slide into the holder below the stage. Once you have inserted the condenser, tighten the set screw (3) to hold the condenser in place.

What is substage condenser?

The substage condenser gathers light from the microscope light source and concentrates it into a cone of light that illuminates the specimen with uniform intensity over the entire viewfield.

What is the substage of a microscope?

Definition of substage : an attachment to a microscope by means of which accessories (such as mirrors, diaphragms, or condensers) are held in place beneath the stage of the instrument.

How do you regulate a substage condenser?

Locate beneath the stage the lever with knurled knob that controls the substage condenser focus (Figure 7-1). Notice that rotating this lever throughout its inclined groove makes the substage condenser move up and down.

What is a substage condenser?

Why does the substage condenser lens have an iris diaphragm?

The opening and closing of this iris diaphragm controls the angle of illuminating rays (and thus the aperture) which pass through the condenser, through the specimen and then into the objective.

What is a substage?

What 2 Adjustments can be made to the condenser?

going from low-power to high-power into oil immersion.

What is substage in medical?

[sub´stāj] the part of the microscope underneath the stage.

Substage Condensers. The substage condenser gathers light from the microscope light source and concentrates it into a cone of light that illuminates the specimen with uniform intensity over the entire viewfield.

How does an Abbe condenser work?

A simple two-lens Abbe condenser is illustrated in Figure 1. In this figure, light from the microscope illumination source passes through the condenser aperture diaphragm, located at the base of the condenser, and is concentrated by internal lens elements, which then project light through the specimen in parallel bundles from every azimuth.

How do you portray Augustine’s relationship with the concubine?

Given that he loved the concubine so deeply, as evidenced by his terrible grief after she is sent away, I portrayed their relationship as a deep, erotic friendship. As for Augustine’s faults: well, I do portray him as continuously restless and dissatisfied. This must have been very hard on X. He was also prone to bouts of depression.

How did Augustine come closer to accepting the Christian faith?

Now that he has solved the problem of evil, Augustine has come closer than ever to accepting the Christian faith. He already feels a love for God, but has not yet “settled down” to enjoy God. “I had now found the priceless pearl,” he says, “and I ought to have sold all that I had and bought it – yet I hesitated.”
