Figure 1: A schematic diagram showing how researchers can study radiation from the early universe using an infrared reflective filter with a moth eye structure created by a pulsed laser process.

According to Phillips, most astronomical telescope mirrors use aluminum for the reflective layer, despite the superior reflective properties of silver. “Silver is the most reflective material, but it ...

LASER COMPONENTS has developed highly reflective dielectric mirrors that enable optical telescopes to detect less luminous celestial bodies. The optics cover a wavelength range from 390 nm to 950 nm, ...
