In order to ensure the photon detection in the solar blind region, the design work of optical receiving and conversion has several important links need to carefully .

First, as the ultraviolet optical system in front of the sensor, in view of the ultraviolet lamp band  or ultraviolet led strip is special,The work of design requires special consideration.

Second, the UV lamp filter is blind and realize photon detection portal, Big enough to consider that maximum suppression of background and the maximum signal via tradeoffs. Since the optical receiving surface is large, the molding.requirements is low than band rough filter radiation suppression.
