| Photosensor Modules H8249 Series The H8249 series photosensor modules incorporate a 28-mm (1-1/8") diameter side-on photomultiplier tube, a high-voltage power supply circuit and a low noise amplifier. Two types of amplifiers are available with a current-tovoltage conversion factor of 1 V/A or 0.1 V/A and a frequency bandwidth of DC to 20 kHz or DC to 200 kHz. Three types of photomultiplier tubes are provided as standard lineups for general applications in the visible range, UV to visible range requiring low-noise, and UV to near IR range. Product Variations Type No. Spectral Response Current-to-Voltage Frequency Bandwidth Features Conversion Factor For general applications in visible range H8249-001 300 nm to 650 nm For general applications in UV to visible range H8249-011 185 nm to 680 nm 1 V/A DC to 20 kHz High sensitivity in UV to near IR range. Uses photomultiplier H8249-101 185 nm to 900 nm tube with meshless grid for excellent uniformity. For general applications in visible range H8249-002 300 nm to 650 nm For general applications in UV to visible range H8249-012 185 nm to 680 nm 0.1 V/A DC to 200 kHz High sensitivity in UV to near IR range. Uses photomultiplier H8249-102 185 nm to 900 nm tube with meshless grid for excellent uniformity. Specifications Parameter Suffix Input Voltage Max. Input Voltage Max. Input Current Max.
