Eclipse When designing the housing, refer to the dimensional allowance as shown in the figure below. Basic Functions Spectral Sensitivity Characteristics Use the graph as a reference value. (We can not guaranttee these values.) This data is measured when the IR cut filter is removed and the characteristics of the lens and optical source characteristics are ignored. Eclipse of the Lens The eclipse phenomenon occurs with the FCBEX990D/EX990DP. This is because a sufficient amount of aperture is not available due to the CCD size and the lens structure of the FCB-EX990D/ EX990DP. However, it has been verified that the eclipse will not be visible in the case of a more than 90 % effective image. For your reference, see the following diagram. B/20=5% A/20=5% B/20=5% Vibration Specifications Test Method (Random vibration) • Fix the camera at the four fixation points of the base using M2 screws. • Perform the random vibration test under the following conditions in the X, Y and Z directions for 20 minutes in each direction. • The camera vibration specification is to have no malfunction after this test.
