WAS IT ERIKSON'S DISCOVERIES MADE OR BENEFITS OF THE WORLD?

The non-optical telescope, primarily radio telescopes, were invented in the 1930s. One of the first and most notable radio telescopes was built by Karl Guthe Jansky in 1931.
There are telescopes used to detect radio waves and others to detect infrared radiation.
They don't. All earth bound telescopes, optical or not, must deal with a number of issues. But what do you mean by "better"? A radio telescope is better suited to pick up radio waves than an optical telescope, but an optical telescope is better for visible light. They each serve their purpose better than the other.
All types of lens that see parts of the electromagnetic spectrum other than light. E.g. infrared cameras
light is must for optical microscope while is not necessary for nonn optical one
No. The Hubble Space Telescope is an optical telescope of the reflective type. A 'non optical' telescope would be one that works on different portions of the electromagnetic spectrum below or above the optical wavelengths.
Optical measures visible light, Radio measures electromagnetic radiation in that part of the spectrum corresponding to radio waves. Same with X-ray telescopes and x-rays. Optical is the kind you look through.
silicon is opaque
See things that don't shine in the visible spectrum.
Visible light is a very narrow range of the electromagnetic spectrum. Even audible sound, at the very bottom, is part of this EM spectrum. Radio and other types of 'scopes are designed to 'see' these other ranges, often with surprising results. The space telescope employs more than visible light capabilities, as do many Earth and space-bound telescopes. Looking at Saturn in visible light is quite breath-taking, but in ultra-violet (UV) a remarkable geometric pattern is visible on one of its poles.
Those terms are most commonly used for optical telescopes. However, the same design can be used for non-visible frequencies; for example, radio telescopes of the "satellite dish" variety are essentially reflecting telescopes.
