Optical Design

VY Optoelectronics（VY）, a renowned provider of optical components, vy can provide a variety of infrared material products including germanium and silicon。IR materials are appropriate for applications such as electro-optic sensors, medical imaging,missile and rocket windows, spectroscopy, and thermal imaging.  Advantages of silicon materials： Cubic in nature and will not exhibit birefringence High environmental durability Silicon is lower in density making it ideal for weight-sensitive applications when compared to other popular IR materials such as germanium and zinc selenide Thermal stability More cost-effective for mid-wave applications than other IR materials Advantages of germanium material： Highest refractive index and lowest optical dispersion of commonly available IR-transmitting materials Germanium is relatively hard with high-density making it ideal for IR applications requiring rugged optics Generally, an anti-reflection coating is recommended on germanium windows for sufficient transmission in the region of interest Subject to…

An aspheric lens can be designed to minimize aberration by adjusting the conic constant and aspheric coefficients of the curved surface of the lens. The most notable benefit of aspheric lenses is their ability to correct for spherical aberration, an optical effect which causes incident light rays to focus at different points when forming an image, creating a blur. Spherical aberration is commonly seen in spherical lenses, such as plano-convex or double-convex lens shapes, but aspheric lenses focus light to a small point, creating comparatively no blur and improving image quality. Now we’d like to introduce roughly one way to manufacture a aspheric lens. ● Firstly, use aspherical milling equipment to grind the aspherical surface. The circular grinding wheel is installed on the above axis and rotates at high speed.…
