SMPX500 Series of Hybrid Detectors The SMPX500 series is a range of integrated photodiode amplifiers incorporating a 1.75mm² silicon PIN photodiode, operational amplifier and transimpedance circuitry. The devices provide a voltage output proportional to incident light. Features Incorporation of the photodiode and amplifier into a welded metal can minimises noise pickup, leakage current errors and stray capacitance normally associated with discrete designs. Gain and bandwidth options are available to suit a wide range of applications and the devices can be operated from single or dual rail supplies. Lens or Flat window can versions are available to suit the application, as well as optical filters to minimise unwanted signals. Applications These devices are especially suited to low-light level or applications where high sensitivity is required: • • • • • • • Medical instruments Document verification Laboratory instrumentation Position and proximity detectors Pollution/environmental monitoring Smoke/Gas detectors Complements SMPX600 range of Self-Monitoring Emitters Spectral Response Custom filters available on request 1 0.8 Unfiltered 0.6 Relative 0.4 Output BG18 RG850 0.2 U340 0 200 400 600 800 1000 1200 Wavelength (nm) Semelab Plc reserves the right to change test conditions, parameter limits and package dimensions without notice.
