1 www.hamamatsu.com apd module variable gain, stable detection even at high gain c10508-01 the c10508-01 consists of an apd, current-to-voltage converter, high-voltage power supply circuit as well as a microcontroller for compensating temperature with high stability on the basis of information received from the temperature sensor. the microcontroller contains coef cients according to the temperature characteristics of the apd. this allows highly stable apd gain over a wide temperature range even at high gain. the gain can be adjusted using a switch on the circuit board or commands from a pc. dc 10 100 1 k 10 k 100 k 1 m 10 m 100 m 1 g sensitivity (v/w) response speed (hz) 10 9 10 8 10 7 10 6 10 5 10 4 10 3 c12703-01 dc to 100 khz -1.5 10 8 v/w c10508-01 dc to 10 mhz 1.5 106 to 1.5 107 v/w c12703 series dc to 10 mhz 1.5 10 6 v/w c5658 50 khz to 1 ghz 2.5 10 5 v/w c12702 series 4 types available for different photosensitive areas and wavelengths 4 khz to 100 mhz -1 10 4 v/w gain temperature stability: 5 % or less (gain=250, ta=0 c to +40 c) adjustable gain the gain can be adjusted with a switch or commands sent from a pc. compact and lightweight easy handling: requires only a 5 v power supply. features apd evaluation optical power meters low-light-level detection applications block diagram sensitivity vs. response speed 5 v bnc connector microcontroller (temperature compensation circuit) voltage controller high voltage generator +200 v +5 v apd temperature sensor i/o high-speed current-to-voltage converter kaccc0360ea kaccb0355ea
