Crystal Lens technology represents an absolute breakthrough in welding optics, achieving a world-record brightness level of 2.0. With a light transmission of 31% in the inactive state, the image seen through the filter is virtually identical to looking through a clean glass. Combined with the True-Color filter, this technology provides a crystal-clear, high-contrast and color-faithful view of the welding pool. This enables precise observation of the metal melting process, which is crucial in demanding methods such as TIG welding. An investment in CLT 2.0 is an investment in the highest possible quality and control of the welding process.

ShadeTronic® technology is an intelligent system that completely automates shade level selection, freeing the welder from the need for manual adjustment. Advanced sensors continuously measure the intensity of the welding arc and adjust the shade level in real time, in a fraction of a second, from 4 to 12 DIN. The system also allows for individual calibration within ±2 DIN to adjust its performance to personal preference. This allows the welder to concentrate fully on precise torch guidance, confident of optimal protection under all conditions. This is a direct result in higher productivity and less mental fatigue while working.

FadeTronic® is a patented technology that controls the filter brightening process after the welding arc is extinguished. Instead of an abrupt transition from dark to bright, the system provides a smooth, gradual brightening in an adjustable range of 0.1 to 2.0 seconds. Such a mechanism significantly reduces fatigue and stress on the eyes, allowing them to gently adapt to the change in light intensity. This is especially noticeable during tack welding or when frequently striking and extinguishing the arc. It’s a fundamental investment in long-term visual health and daily working comfort.

The True-Color filter, which is standard on Optrel’s advanced models, uses a special coating that transmits a much wider color spectrum than traditional filters. This eliminates the characteristic green tint, providing a natural, high-contrast, full-color image of the environment. In practice, this means being able to flawlessly read color LED indicators on the welder panel or distinguish material markings without lifting the visor. This increases not only comfort, but also productivity and safety on the job site.

The silver shell of the crystal 2.0 visor has been coated with a specialized paint with thermal insulating properties. This advanced coating effectively reflects a significant portion of the thermal radiation emitted by the welding arc, especially when working with high currents. As a result, the temperature inside the visor remains perceptibly lower, which directly affects the welder’s comfort. This is a key feature during prolonged work or in hot environments, reducing fatigue and maintaining concentration.
