On the other hand, with the P-incidence structure used by Matsusada Precision, the generated carriers from the light incidents near the surface enter the avalanche layer with 100% certainty. There are no lattice defects in the crystal, resulting in a low-noise device. Furthermore, since a stable P layer can be formed, the variation in the avalanche voltage of each device can be suppressed.

K2 and X1 are Kodak (Wratten) type indicators. These letter andnumber combinations date back to the first filters and have littlerational basis. Other filter manufacturers used other letter andnumber designators (although some adopted the Wratten system), like Y2for K2, lists can be found in many old handbooks. Some filter makerssimply named the filters, i.e. Medium Yellow. The number only system became a standard about the mid seventiessometime. Other systems continued to co-exist for many years. Thenewer system is consistant amoung manufacturers so a #11 is the samething regardless of who makes it. That is not to say the quality orexact spectral transmission will be the same but it will be a mediumGreen filter and not something completely different. There have been a tremendous number of filters offered commerciallyover the years including a great many special purpose filters and somepretty close duplications. Many of these have disappeared due tolittle volume or the use of un-stable colorants. The most commonly used filters for B&W are:Old Wratten No. New type no.

An Avalanche Photodiode (APD) is a type of photodiode in a photodetector. An APD applies a high voltage to increase the photosensitivity compared to a normal photodiode. The application of a high voltage causes an avalanche phenomenon, which amplifies the signal. This makes it possible to obtain signals with high sensitivity even in weak light.

The greatest feature of Matsusada Precision's APDs is that they use a P-incidence structure. Most of the other companies use an N-incidence structure, and especially with short-wavelength light, the carriers are generated before the avalanche layer without reaching the depletion layer, so the avalanche effect is not 100% achieved and the sensitivity drops.
