Photomultiplier Type
           
   Your choices are...         
   Side-on Photomultiplier       These detectors are more economical than end-on models, have the fastest rise times and are ideal for photometry and spectrophotometry applications. Their vertical configuration takes up less space than the end-on versions. They mount in the standard or pulsed housings. The main disadvantage of these tubes is their non-uniform sensitivity. 
   End-on Photomultiplier       Sometimes known as head-on photomultipliers, these detectors offer better spatial uniformity and photosensitive areas from tens of square millimeters to hundreds of square centimeters. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Active Area
   Active Area Diameter or Length:       The area of the active part of the detector.  The diameter of the active area if circular, the length of the active area otherwise. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Active Area Height:       If the active area of the detector is not circular, the height of the active area. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Photomultiplier Performance
   Spectral Response Range:       The spectral response range of incident light the photomultiplier tube detects, also called wavelength range. 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
   Sensitivity:       A measure of the effectiveness of a detector in producing an electrical signal at the peak sensitivity wavelength. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Rise Time:       The time necessary for a detector's output to go from 10% to 90% of its final value. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Applied Voltage:       The Anode to Cathode Voltage for the Photomultiplier Tube. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Gain:       The factor by which the current generated by a photon is increased before the signal is detected, also known as current amplification. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Photomultiplier Noise
   Dark Current:       The current associated with a detector during operation in the dark with an applied voltage. Increased temperature and applied voltage will result in increased dark current. Also, larger active areas will generally have a higher dark current. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Noise Equivalent Power (NEP):       The power of incident light, at a specific wavelength, required to produce a signal on the detector that is equal to the noise. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
