    2021-6-1 · The S1133 is a ceramic package photodiode that offers low dark current. Ceramic package used is light-impervious, so no stray light can reach the photosensitive area from the side or backside. This allows reliable optical measurements in the visible to near infrared range, over a wide dynamic range from low light levels to high light levels.

  • Hamamatsu Avalanche Photodiodes | Edmund Optics

    Si APDs are used when light signals are too high for photomultiplier tubes and too low for conventional photodiodes. Si APDs are often used in high-speed applications since the excess noise from the avalanche process is still lower than the noise that would be generated in connecting an external amplifier to a conventional photodiode operated at high frequencies.

    Light is diffused by reflecting from or transmitting through an irregular (rough) surface. Typically, precautions are taken to remove diffusion in applications; however, diffusers can be utilized to introduce a specific amount of diffusion in order to create a desired effect (i.e. minimizing glare, homogenating a beam, removing speckle in a laser application, etc).
