Quantum efficiency: The number of carriers (electrons or holes) generated per photon. Responsivity: The output current divided by total light power falling upon the photodetector. Noise-equivalent power: The amount of light power needed to generate a signal comparable in size to the noise of the device.
A vestibule is composed of an ACBM ring (1) mounted to a flanged bulkhead (3) and a PCBM ring (2) mounted to a flanged bulkhead or barrel section (4). The rings, both machined from 2219 Aluminum forgings, mate at a "molded seal" (5); each ring is sealed at its inboard end by a pair of concentric o-rings (6).
Opto-isolator VTL2C1 with LED input and photoresistor output. Resistive opto-isolator (RO), also called photoresistive opto-isolator, vactrol (after a genericized trademark introduced by Vactec, Inc. in the 1960s), analog opto-isolator [notes 1] or lamp-coupled photocell, [1] is an optoelectronic device consisting of a source and detector of light, which are optically coupled and electrically ...
A double DIN 1.6/5.6 bulkhead jack connector, crimp type, for 75 Ω coaxial cable A Type N connector (male), right-angled solder-type for semi-rigid coaxial cable with a diameter of 0.141-inch. 4.1-9.5 connector, standardized as DIN 47231 (in 1974) and IEC 60169-11 (in 1977) 4.3-10 connector, formerly known as DIN 4.3/10, now standardized as ...
A keystone module is a standardized snap-in package for mounting a variety of low-voltage electrical jacks or optical connectors into a keystone wall plate, face plate, surface-mount box, or a patch panel. Keystone modules have a rectangular face of 14.5 mm wide by 16.0 mm high and are held in place with flexible tabs.
Three photoresistors with scale in mm Large CdS photocell from a street light. A photoresistor is less light-sensitive than a photodiode or a phototransistor. The latter two components are true semiconductor devices, while a photoresistor is a passive component that does not have a PN-junction. The photoresistivity of any photoresistor may vary ...
The aft pressure bulkhead is the white circular component; its web-like structure led a NASA technician to attach a large model spider to it for comedic effect. The aft pressure bulkhead or rear pressure bulkhead is the rear component of the pressure seal in all aircraft that cruise in a tropopause zone in the Earth's atmosphere. [ 1 ]
The coupling has a 5 ⁄ 8-24 UNEF thread. Amphenol suggests tightening to a torque of 15 inch-pounds (1.7 N⋅m), [2] while Andrew Corporation suggest 20 inch-pounds (2.3 N⋅m) for their hex nut variant. As torque limit depends only on thread quality and cleanliness, whereas the main operational requirement is good RF contact without ...
