Optrel 5000.300: Inner Cover Lens 107x51mm (1 pc.)
Genuine Optrel inner cover lenses (cat. no. 5000.300) are a key consumable, designed to protect the most valuable part of the helmet, the auto-darkening filter (ADF). The lens, cut precisely to 107 x 51 mm and fitted with a dedicated metal mount, gives an exact fit and reliable protection in the e640, osc, OSE and b600 series. Replacing this lens regularly is the basis for keeping optical quality high and for significantly extending the life of the whole protective system.

Technology details
Reliable Protection of the Auto-Darkening Filter (ADF)
The inner cover lens is the first and most important barrier protecting the delicate inner surface of the auto-darkening cartridge. It is constantly exposed to dust, sweat and the fine mechanical scratches that appear during normal use and maintenance of the helmet. Made of high-quality polycarbonate, the lens absorbs these hazards and prevents permanent damage to the far more expensive ADF. Replacing a worn lens regularly is a key part of preventive maintenance. It is a simple and very economical way to protect the heart of the helmet and avoid costly repairs or replacement of the whole ADF cartridge.
Keeping Optical Quality Intact
Even the smallest scratch, haze or dirt on the surface directly in front of the welder's eyes scatters light and degrades vision. It affects colour perception, sharpness and overall comfort, and leads to faster eye fatigue. A clean, new inner lens ensures that the full potential of the filter optics, such as True-Color View, is actually used, giving you an image free of distortion and artefacts. Regular lens replacement is an investment in precise work, less eye strain and full use of the advanced optics in your Optrel helmet.
