Closing the iris diaphragm reduces the amount of light entering the lens, resulting in a darker image with decreased brightness. However, this reduction in light can potentially improve contrast by reducing any glare or overexposure in the image.
Opening the diaphragm under the stage of the microscope allows more light to pass through and brightens the image. Closing the diaphragm reduces the amount of light reaching the specimen, which can help reduce glare and improve contrast in the image. Adjusting the diaphragm is important for optimizing image quality and clarity.
Closing the diaphragm increases image contrast by reducing the amount of scattered light entering the camera lens. This helps to minimize unwanted glare and reflections in the image, resulting in clearer and more defined subject details. Additionally, it helps to improve the sharpness and overall quality of the photograph.
A diaphragm lever is a mechanical component that connects the diaphragm in a pressure system to a control mechanism. It is designed to translate the movement of the diaphragm into an action, such as opening or closing a valve, based on the pressure changes detected by the diaphragm. This helps regulate and control the flow of a fluid or gas in a system.
The effect of a cracked diaphram in transmission is that it reduces the efficiency of the system.

Closing the iris diaphragm reduces the depth of field, making it easier to distinguish between overlapping threads in the image. By decreasing the amount of light entering the microscope, you can increase contrast and resolution, improving visibility and making it easier to determine the thread order.
The optical characteristics of most lenses dictate that to obtain maximum optical quality, you ought to stop down at least 3 stops from maximum, as a general rule of thumb.
You would adjust the diaphragm in a microscope to control the amount of light passing through the specimen. Opening the diaphragm allows more light to pass through, while closing it reduces the amount of light.
