Optical Shutter - With 5V or 3.3V direct drive, the LST-5VDC optical shutter provides the best value. In terms of package size to aperture size, it's compact 2" x 1" x 0.4" package offers the best balance between package and aperture size. The electrical drive becomes the most straightforward form when using a 5V or 3.3V direct drive. Thermal management becomes negligible with only 2.5W thermal power dissipation when holding open.
An optical shutter is a device that is used to control or regulate the amount of light that passes through an optical system. It is essentially a device that can selectively block or allow light to pass through an aperture or a lens, and is commonly used in various applications such as photography, microscopy, laser experiments, and other scientific research applications.
The function of an optical shutter is to selectively interrupt or allow the flow of light through an optical system. This can be achieved in several ways, including the use of mechanical or electronic shutters. A mechanical shutter works by physically blocking the light path using a movable component, such as a blade or curtain. An electronic shutter, on the other hand, uses an electronic signal to control the opening and closing of a light-blocking element, such as a liquid crystal display (LCD) or a polarizing filter.
Optical shutters are commonly used in cameras to control the amount of light that reaches the film or image sensor. In photography, the shutter speed determines the duration of time that the camera's shutter remains open, allowing light to reach the sensor or film. A fast shutter speed allows for a shorter duration of exposure, resulting in a freeze-frame effect that can capture fast-moving subjects without blurring. A slow shutter speed allows for a longer exposure time, resulting in a blurred motion effect that can be used to create artistic effects or capture low-light scenes.
