Optrel Crystal 2.0: replaceable auto-darkening filter (ADF)
The Optrel Crystal 2.0 auto-darkening filter (ADF) is the heart and brain of the most advanced Optrel welding helmets.

With Crystal Lens Technology 2.0, the ShadeTronic® autopilot and compatibility with many shells from the Sphere series, this filter takes your view and the automation of your work to the top level. It suits professionals who want to update their Optrel helmet with the latest optical technology without replacing the whole shell.

Technology details
Crystal Lens Technology 2.0, a crystal-clear view
Crystal Lens Technology (CLT 2.0) sets a new standard for what a welder can see, with a light state of 2.0 when the filter is inactive. With 31% light transmission and a True-Color filter, the view through the filter is almost undistorted, with natural colours and very high clarity. You can prepare the material, position the torch and inspect the weld after welding without lifting the helmet. CLT 2.0 gives you better work quality, less eye strain and full control over the welding process.
ShadeTronic®, intelligent shade autopilot
ShadeTronic® works like a personal assistant that looks after your eye protection in real time. A set of advanced sensors continuously measures the intensity of the welding arc and adjusts the shade automatically, without any input from you, in the range from 4 to 12. Whether you change the welding process, the current or the working angle, the system keeps the shade at the right level. This means uninterrupted work and maximum safety, so you can concentrate fully on the precision of the weld.
FadeTronic®, smooth brightening for eye comfort
FadeTronic® is a patented technology for a smooth transition from the dark to the light state after the arc goes out. Instead of a sudden flash of brightness, the filter lightens gradually over an adjustable time from 0.1 to 2.0 seconds, giving your eyes time to adapt comfortably. This small detail matters a great deal for welders who make hundreds of welds a day, because it greatly reduces fatigue and strain on the eyes. It supports long-term eye health and comfort, which helps you stay focused and productive during long shifts.
Modularity and compatibility: upgrade instead of replace
This auto-darkening filter is designed for the modular Optrel system, which is one of its biggest advantages. It is fully compatible with many helmet shells, including the crystal 2.0, vegaview 2.5, e684, e680, e670 and e650 models. This gives you a way to bring an older but still serviceable helmet up to the latest optical standard without the cost of a completely new unit. It is a smart and economical way to access current technology while extending the life of the equipment you already own.
