Can one make a fiber optic cable lighting pen using infrared light by oneself?
Theoretically, it is possible to make such products by oneself, as long as they are not products that require special qualifications for production due to regulatory constraints, and one is able to create products whose performance and functionality meet the required standards. However, this price doesn’t seem to be that high either, and ordinary users generally don’t need much of it – is it really necessary to make it oneself?
