MODULE Photosensor amplifier C9329 Digital output function, current-to-voltage conversion amplifier for amplifying very slight photocurrent with low noise C9329 is a current-to-voltage conversion amplifier used to amplify very slight photocurrent from a photodiode with very low noise. Three ranges of photocurrent detection sensitivity level (H, M, L) are selectable to match the input signal. C9329 operates on the built-in dry batteries so it can be easily used anywhere. C9329 can be directly connected to a personal computer through the RS-232C interface allowing you to acquire highresolution (16-bit) digital output signals and use the data logger function.

When you use a photodiode metal package, use an insulator to electrically insulate and also hold the package in a shield case as shown in the figure at right. Connect the anode to the shield case. Any single-element photodiode with a terminal capacitance below 5000 pF can be used. Using a photodiode with anode grounded is recommended. Using a photodiode with a BNC connector (S2281 series) allows you to easily make measurements because it connects to C9329 with a BNC-BNC plug coaxial cable.

Photodiode, coaxial cable with BNC-BNC plug and RS-232C cable are not supplied with C9329. You will need an RS-232C cable (straight cable terminated with a D-sub 9 pin female connector at both ends) available from electronics supply houses. 2 PHOTODIODE Si photodiode S2281 series Si photodiode with BNC connector S2281 series photodiodes are sealed in a metal package with a BNC connector and designed to connect to C9329 photosensor amplifier. Two different spectral response ranges are provided. The large active area makes S2281 series suitable for optical power meters. A variant type S9219 with a visual compensation filter is also available.Hamamatsu also provides E2573 BNC-BNC coaxial cable (length: 1 m) as an option. ■ G e ne ra l ra ting s P a ra m e te r A ctive a re a size A ctive a re a P a ck a g e W in d o w m a te rial S2281 φ1 1 .3 100 S 2 2 8 1 -0 1 φ1 1 .3 100 M e ta l w ith B N C c o n n ec to r Q u a rtz g la s s S 2 2 8 1 -0 4 φ7 .9 8 50 U n it mm 2 mm - S2281 S 2 2 8 1 -0 1 5 -1 0 to + 6 0 -2 0 to + 7 0 S 2 2 8 1 -0 4 U n it V °C °C ■ A b solu te m axim um ra ting s P a ra m e te r R e ve rse vo lta g e O p e ra tin g te m p e ra tu re S to ra g e te m p e ra tu re S ym b o l V R M a x.
