In general, ten-element transmission trap detector consists of 6- and 4-element photodetectors mounted optically in series. Our design yields in extremely low output beam - 100000 times less optical power than in input beam. By rotating the device around horizontal axis, the optical power in the transmitted beam can, additionally, be attenuated about 20 times. The predicting and interpolation capabilities of the transmittance and the responsivity are well-maintained due to use of quality photodiodes in the device. The 10-element photodetector is useful for measurements of optical power where high attenuation and analysis of transmitted beam are required
