Spectral Response
The quantum efficiency of the PMT module is compared in the following graphs. Quantum efficiency is the conversion ratio of photoelectrons per photon and is a very important factor that determines the S/N characteristic.It is essential to select a PMT module having high quantum efficiency on the wavelengths of light to be measured. To obtain a lower detection limit with a good S/N ratio in low-light-level measurement, the dark current and dark count must also be considered as well as the quantum efficiency.

Precautions
Safety precautions
|
|
|
 |
Subject to local technical requirements and regulations, availability of products included in this promotional material may vary. Please consult with our sales office.
Some products listed in this catalog generate a high voltage internally. Be sure to observe the following safety
measures and take sufficient precautions to prevent possible electrical shocks.
Always turn off the power before moving, installing and inspecting the products or connecting/disconnecting the cables and connectors.
Do not modify any part of the product and do not open the housing case. Malfunctions or electrical shocks might result and the products might overheat, smoke or catch fire. |
Handling precautions
Take the following precautions when handling PMT modules.
Do not expose the photocathode of PMT modules to excessive light such as sunlight. If exposed, noise will increase and photocathode sensitivity will deteriorate.
Do not touch the light input window with bare hands. Dirt and grime on the window causes loss of optical transmittance. If the window becomes soiled with dirt or grime, wipe it clean using alcohol.
Helium will penetrate through silica (quartz) glass windows and increase noise. Avoid using or storing those PMT modules in an atmosphere where helium is present.
Carefully check that the power supply output voltage and polarity are correct.
Do not apply strong vibrations or impacts to PMT modules.
Do not apply a strong tightening force to localized sections.
Do not let moisture or dust penetrate inside.
Consult with us if you must take special countermeasures against tough conditions such as high temperatures, high humidity or strong magnetic fields.
When designing equipment using or incorporating products listed in this catalog, install safety interlocks (breakers, etc.) to prevent accidents from electrical shocks or excessive light input, etc.

Warranty
Hamamatsu PMT modules and related products are warranted to the original purchaser for a period of one year after delivery. The warranty is limited to repair or replacement of defective products due to defects in workmanship or materials used in their manufacture.
Even if within the warranty period, the warranty shall not apply to failures due to misuse, mishandling, modification by the customer, or accidents such as natural or manmade disasters.
The customer should inspect and test all products as soon as they are delivered. |
