FCI-InGaAs-XXX series with active area sizes of 75 µm, 120 µm, 300 µm, and 500 µm, exhibit the characteristics and need for Datacom and Telecom applications. Low capacitance, low dark current and high responsivity from 1100 nm to 1620 nm make these devices ideal for high bit rate receivers used in LAN, MAN, WAN, and other high speed communication systems. The photodiodes are packaged in 3 lead isolated TO-46 cans or with AR coated flat windows or micro lenses to enhance coupling efficiency. FCI-InGaAs-XXX series is also offered with FC, SC, ST and SMA receptacles.

One method for applying band-pass filters to images is to subtract an image blurred with a Gaussian kernel from a less-blurred image. This example shows two applications of the Difference of Gaussians approach for band-pass filtering.

Band-pass filters attenuate signal frequencies outside of a range (band) of interest. In image analysis, they can be used to denoise images while at the same time reducing low-frequency artifacts such a uneven illumination. Band-pass filters can be used to find image features such as blobs and edges.
