2. Describe two methods of locating a slide for viewing on the SI V-Scope.
3. List the steps that must be completed before selecting a slide for viewing on the SI V-Scope.
4. What would occur if an unfocused slide image was downloaded?

Answer 1

The coarse focus knob on the SI V-Scope has two functions: large-scale movements for focusing and quick focusing with lower magnification lenses. Two methods of locating a slide include moving it using the mechanical stage knobs and scanning it with the high-power objective lens. Before selecting a slide, you need to place the specimen on a glass slide, secure it on the stage, and position it over the light. An unfocused slide image would appear blurry and lack detail.

Step-by-step explanation:

• The coarse focus knob on the SI V-Scope has two main functions:

It is used for large-scale movements when adjusting the focus of the microscope.

It is primarily used with lower magnification objective lenses, such as the 4x and 10x, to quickly bring the specimen into focus.

• There are two common methods to locate a slide for viewing on the SI V-Scope:

Using the mechanical stage knobs, the slide can be moved on the surface of the stage to position the specimen over the light, allowing for easy viewing.

By scanning the slide left to right and up and down using the high-power objective lens, all the cells on the slide can be viewed.

• Before selecting a slide for viewing on the SI V-Scope, the following steps must be completed:

Place the specimen on a glass slide.

Secure the slide on the stage of the microscope.

Use the mechanical stage knobs to position the specimen over the light.

• If an unfocused slide image was downloaded, the image would appear blurry and lacking in detail. It would be difficult to accurately observe and study the specimen.

Answer 2

1. Functions of the coarse focus knob include:

(1) that it raises and lowers the microscope stage

(2) it is used to originally focus on low power. Prior to choosing a new slide, always lower the stage.

2. To locate a slide for viewing, select from slide library or viewing panels. The slide library has titles to select or can locate by using search bar.

3. the steps that must be completed before selecting a slide for viewing on the HOL V-Scope are:

• Prior to selecting a slide for viewing: Locate and select the coarse focus knob. Prior to choosing a new slide, always lower the stage by sliding the ruler indicator to "0."
• Locate and select the illuminator on/off switch. Turn the illuminator on by toggling the switch to the "ON" position.
• Locate and select the turet–Toggle the turet control to choose the lower power (4x)objective lens

4. Since downloaded images represent the images seen in the viewing panel, the downloaded image won’t be focused either

So, the coarse focus knob on the SI V-Scope serves two primary functions It allows for a quick and rough focusing of the slide at low magnifications to bring the image into a generally clear state.
