Seiwa 1.2 inches HR Telecentric LensSeiwa introduces New FHL series telecentric lenses which support 25MP with C-Mount. This FHL series has a high-resolution design that supports sensors with a pixel of less than 3 um, and we offer five models according to the magnification. The New FHL series telecentric lens is compatible with the BU2409M series USB3 Vision CMOS Camera. Sensors in Machine Vision Cameras are trending toward high resolution and image size within the C-Mount standard due to the miniaturization of pixel size. BU2409M series use the latest Sony "Pregius S" sensor (IMX540) to achieve a high resolution of 24.5MP with a C-Mount standard camera while having a pixel size of 2.74 um square pixels.

By adopting backside illumination technology, this sensor achieves the same sensitivity as the conventional sensor with a pixel size of 3.45 um. With the backside illumination technology, until the light entering from the on-chip lens chip reaches the photodiode, there is no obstruction by the wiring layer unlike the conventional structure, and the distance can be shortened, so the light can be taken in efficiently and the pixel size can be reduced. It is possible to obtain sufficient sensitivity even in the trend of pixel size miniaturization. The image size of the BU2409M series is as large as 1.2 inches.
