Adjustable Range Reflective Photoelectric Sensor
EQ-30
-
Panasonic Industrial Devices Sales Company of America
The compact EQ-30 Adjustable Range Reflective Photoelectric Sensor is only 68 x 20 x 40mm but delivers amazing performance. Normal Reflective Type Sensors operate by sensing the variation in the amount of incident beam. However, the Adjustable Range Reflective Sensing Type Sensors, incorporate a 2-segment photodiode to sense variation in the incident beam angle. Thus, the output is activated according to the distance of the object from the Sensor. This system helps the EQ-30 Series to be unaffected by object color or a background, enabling stable sensing. The robust housing offers IP67 protection allowing the EQ-30 Sensor to be used in the most demanding industrial environments.

Low Input Bias Current Op Amps (≤100 pA)
-
Low input bias current op amps are required whenever the difference of currents or voltage is small and needs to be measured accurately. These op amps are used so that the signal is not loaded down by the input of the op amps. Low input bias current op amps are critical for interfacing sensors in applications from photodiodes, pH meters, or other electrometer related functions to downstream electronics. Analog Devices has many precision op amps that fit the definition and range of these applications.

Streak Camera
OptoScope S3C-1
-
The S3C-1 is a streak camera based on a semiconductor sensor. Like tube-based streak cameras, the S3C-1 captures changes in light along a line and records the change over time. To record the intensity values, they are sampled and stored with up to 2 GSamples/sec. The line is 65 µm wide and consists of 200 elements along its 5 mm length. Each element consists of a sensitive photodiode with a downstream amplifier.A new and special camera feature is continuous recording. This makes it possible to take recordings of events for which precise information about the time of their occurrence only becomes available after they have taken place. This "post-triggering" simplifies or allows certain applications.

PIN Photodiode
-
PIN photodiode is a kind of photo detector, it can convert optical signals into electrical signals.This technology was invented in the latest of 1950's. There are three regions in this type of diode. There is a p-region an intrinsic region and an n-region. The p-region and n-region are comparatively heavily doped than the p-region and n-region of usual p-n diodes. The width of the intrinsic region should be larger than the space charge width of a normal p-n junction. The PIN photo diode operates with an applied reverse bias voltage and when the reverse bias is applied, the space charge region must cover the intrinsic region completely. Electron hole pairs are generated in the space charge region by photon absorption. The switching speed of frequency response of photo diode is inversely proportional to the life time. The switching speed can be enhanced by a small minority carrier lifetime. For the photo detector applications where the speed of response is important, the depletion region width should be made as large as possible for small minority carrier lifetime as a result the switch speed also increases.
