Probe domestic double-head probe 038-BB-5.7L The shape of the two ends of the needle is outside the pointed needle
Vacuum tubes are also present and useful in certain applications, such as in this continuous wave transmitter. This circuit was built on a wooden vintage breadboard. The old watch radio is a good source of this circuit part. V3 is used as a ballast resistor, and a 75Ω or 100Ω 5W resistor can be replaced.
Right angle prisms are usually used to turn the optical path or deflect the image formed by the optical system by 90 °. According to the different orientation of the prism, the imaging can be consistent from left to right and reversed from top to bottom, which is different from left to right. Right angle prism can also be used in image combination, beam offset and other applications.
Right angle prism: it is one of the basic functions of right angle prism to efficiently reflect the incident light inside by using the characteristics of critical angle.
