The diaphragm has a non-negligible role in the optical system, in the optical system, the diaphragm can limite the beam, which is mainly used to control the light intensity, reduce aberration and increase the depth of focus and other purposes. Through reasonable design and use of the diaphragm, the imaging quality and performance of the optical system can be improved to meet the needs of different application scenarios.
The smaller the aperture of the diaphragm, the smaller the aberration, and the greater the depth of field, the clearer the image, but the brightness will be reduced, so the diaphragm control is particularly important when using the diaphragm. CoreMorrow N61.R5E rotation stage can be applied to diaphragm control, which can effectively control the diameter of the hole in the diaphragm to adjust the light transmittance through the hole.
N61.R5E Piezo Motor Driven Rotation Stage
N61.R5E piezo motor driven rotation stage is a stepping motor which is directly driven by piezo ceramics. It adopts special mechanical structure design, to convert the linear micro-displacement generated by piezo ceramics into the macroscopic angular rotation motion of the mechanical plane, which can produce 360°rotating motion. The small size makes it very easy to integrate. It has a very high rotation resolution, equipped with incremental encoder, it’s motion is more accurate. Use CoreMorrow E53.D1E piezo controller, we can realize the speed and stroke control through computer software.

N61.R5E Piezo Motor Driven Rotation Stage Applied to Diaphragm Switch
The diaphragm is installed on the rotating moving table of N61.R5E stage, and the E53.D1E piezo controller is operated by software to control the rotation direction and rotation angle of the N61.R5E rotating piezo motor, so as to drive the diaphragm adjusting handle to rotate, and change the diameter of the middle hole of the diaphragm, to finally achieve the purpose of adjusting the light transmission through the hole.
As a diaphragm switch, N61.R5E piezo motor driven rotation stage can be used in semiconductor technology, medical biomicroscopy equipment, image processing and optical equipment manufacturing. In addition to the application of improving the imaging quality in optical systems, in the semiconductor field, with the change of the aperture of the diaphragm, the amount of light transmission changes, which can affect the conductivity of the semiconductor, typical such as photoelectric materials, solar cells belong to a photoelectric material. Due to the photo effect, light interacts with matter, and the change in illumination will change the transformation of its light energy into electrical energy.
