SparkFun Opto-isolator Breakout
-
This is a board designed for opto-isolation. This board is helpful for connecting digital systems (like a 5V microcontroller) to a high-voltage or noisy system. This board electrically isolates a controller from the high-power system by use of an opto-isolator IC. This IC has two LEDs and two photodiodes built-in. This allows the low-voltage side to control a high voltage side.

Phototransistors
-
Phototransistors are photodiode-amplifier combinations integrated within a single silicon chip. The phototransistor can be viewed as a photodiode whose output current is fed into the base of a conventional transistor. These photodiode-amplifier combinations are put together to overcome the major limitation of photodiodes: unity gain. The typical gain of a phototransistor can range from 100 to over 1500.

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.

Photometers & Colorimeters
-
Instrument Systems Optische Messtechnik GmbH
A photometer is used to measure the photometric quantities of illuminance (lx), luminous intensity (cd), luminous flux (lm), and luminance (cd/m²). The integral method and the fast response time of silicon photodiodes means that photometers can achieve an outstanding measuring speed. They are therefore ideal for performing fast goniophotometric measurements. We take great care in the development and production of photometer heads and use innovative amplifier technologies.

PIN photodiodes convert light to current – without a bias voltage having to be applied. Silicon is commonly used as an inexpensive detector material in the Vis range. For higher demands, InGaAs is used; it covers the widest spectral range from the Vis to the NIR. We offer silicon carbide as a “solar-blind” detector specifically for the UV range.

Optical Power And Energy Meters
-
Thorlabs' expanding line of optical power and energy meters includes power meter consoles, a large selection of sensor heads, a wireless power meter with a built-in photodiode sensor, and a fiber optic power meter designed for use in the field. The consoles (PM100, PM400, and PM300 Series) when paired with our extensive line of power and energy sensors provide calibrated (NIST traceable) measurements across a broad range of powers, energies, and wavelengths. The console(s) and sensor(s) can be purchased individually or as bundles based on our most popular console and sensor pairings. The sensor calibration data is stored in the sensor head and is automatically read by the console, which allows the user to use multiple sensors with the same console. Compatible sensors are easily identified by the red c-series connector. All of our old A/B-Type sensors are available with the new connector; plus, we have continued to expand our power and energy sensor product lines.

Avalanche Photodiodes
-
These avalanche photodiodes (APDs) are silicon photodiodes with an internal gain mechanism. As with a conventional photodiode, absorption of incident photons creates electron-hole pairs. A high reverse bias voltage creates a strong internal electric field, which accelerates the electrons through the silicon crystal lattice and produces secondary electrons by impact ionization. The resulting electron avalanche can produce gain factors up to several hundred.

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.
