Aspherical measurement CGH
In the use of CGH, it is important to correctly align the CGH itself!
We provide custom CGHs that have recently begun to be utilized for shape measurement of aspheric and freeform surfaces, as well as for high-precision alignment of complex optical systems. Based on your objectives and usage environment, we will design and manufacture a CGH that generates the desired wavefront with the necessary precision. Even if you are not familiar with CGHs, please feel free to consult with us. Our experienced technicians will propose appropriate methods for you. 【Specifications】 ■ Usable wavelength range: 360nm to 2000nm ■ Substrate size: 100mm x 100mm to 500mm x 500mm ■ Substrate materials: Synthetic quartz, blue plate glass ■ Minimum pattern pitch: 0.5μm *For more details, please download the PDF or feel free to contact us.
