This filter is an enhanced version of our exclusive True Didymium™. It has added infrared absorption that True Didymium™ does not have.
The AGW™-300 is a revolutionary new filter designed for hot glass workers working at the furnace doing gathers and gazing into firepots and scientific and artistic glassworkers who are doing work with clear borosilicate only. This is also an excellent filter for the metalworker who needs high visible light transmission coupled with excellent infra-red (IR, heat energy) filtration and sodium flare filtration. Finally, soft glass workers will also find this filter useful to remove the heat energy you are exposed to while working with large torches and/or large pieces.
The AGW™-300 is a laminated filter with the same transmission characteristics as our original AGW®-186 filter. It comprises a base lens of Blue Didymium and a thin layer of our exclusive lightly tinted IR filter glass. This filter has excellent visible light transmission, averaging 60 to 70%, with excellent absorption of the sodium flare.
Suggested uses are High-pressure torches and temperature applications on hard glasses like Pyrex®, and Vicor®, where high visible acuity is required along with filtration of considerable amounts of infrared radiation.
The AGW-300 filter is only available in non-prescription form.
Thickness Advisory: This filter is thicker than normal lenses. In non-prescription form, it is approximately 5 mm thick.
