Application and principle of high contrast color powder in high contrast lenses

High contrast lenses are professional functional lenses designed to enhance visual clarity in harsh lighting environments. It is mainly used in low light, foggy, rainy, foggy, dusk, and low contrast scenes. The core optical principle lies in the intelligent management of the incident light spectrum through the built-in high contrast color powder (functional optical dye/pigment). Due to their high energy properties,

Application of blue light absorbers in anti blue light lenses

Blue light absorbers are the core of anti blue light technology, which achieve protection by selectively absorbing blue light; Anti blue light glasses are their most popular application products, and when purchasing, attention should be paid to the barrier rate, transmittance, and color cast, and scientifically choose according to their own usage scenarios. However, it should be noted that anti blue light glasses are only auxiliary tools. Reasonable use of eyes and control of electronic device usage time are the fundamental ways to protect vision.

What is the thermal Fuse?

thermal fuse or thermal cutoff is a safety device which open circuits against overheat. It detects the heat caused by the over-current due to short circuit or component breakdown. Thermal fuses do not reset themselves when the temperature drops like a circuit breaker would. A thermal fuse must be replaced when it fails or is triggered.Unlike electrical fuses or circuit breakers, thermal fuses only react to excessive temperature, not excessive current, unless the excessive current is sufficient to cause the thermal fuse itself to heat up to the trigger temperature.

Combination of Two Minerals Can Explain Mysterious UV Absorber in Clouds of Venus

The clouds of Venus are believed to be composed of sulfuric acid and minor constituents including iron-bearing compounds. Respective concentrations of these compounds vary with height in the thick atmosphere of our neighboring planet. In a new study, researchers at the University of Cambridge synthesized iron-bearing sulfate minerals that are stable under the harsh chemical conditions in the Venusian clouds. Their spectroscopic analysis revealed that a combination of two minerals, rhomboclase and acid ferric sulfate, can explain the mysterious ultraviolet (UV) absorption feature in the Venusian atmosphere.
