In the field of light sensor applications, Morrison Optoelectronics provides Ambient Light Sensor, Proximity Sensor, and also provides a variety of different light bands (for example: Multi-channel Band Pass Filter, IR Pass Material, Color Filter). Applications are integrated on the same chip, which not only could greatly reduce the overall cost of wafer manufacturing and packaging, but also because the vertical integration is completed by Morrison Optoelectronics, in addition to shortening the overall process time, it also improves the Quality control capability.
Time of Flight (ToF): Near-infrared light (NIR) is emitted through a light-emitting source (LED or laser), reflected on the surface of the object, and measured through a near-infrared light image sensor. The time when the depth position reflects back, and the distance between different positions of the object can be calculated using a simple mathematical formula. The key is to have a narrow band pass filter in order to accurately receive the light only contains the 940nm band (because this band is not easily affected by nature). In addition to providing this filter film, our company can also integrate semiconductor lithography patterning process and Micro lens manufacturing technology, which greatly helps to improve the sensing performance and extensive use of ToF sensors.
In the field of image sensor applications, Morrison Optoelectronics provides IR absorbing glass applications such as infrared light absorption filters, dual-band absorption filters, etc., which are respectively used in the lens modules of smart phones and notebook computers. We also provide customized theater-grade optics for specific customers.
Morrison Optoelectronics can complete customized multi-spectral integration graphics services on wafers and glasses, including space-grade filters and black matrix with high penetration and low reflection for vehicles.
MOE cooperated with domestic semiconductor manufacturers to develop a digital gradient filter for advanced semiconductor exposure machines, which was adopted by domestic and foreign semiconductor manufacturers. Applicable to ASML PAS5500/ 550 or 700 (DUV), 200 or 400 (i-line).
