This filter is an enhanced version of the AUR^®-92. It has added infrared absorption that the AUR^®-92 does not have.

The AGW^®-300 is a revolutionary new filter designed for hot glass workers that are working at the furnace doing gathers and gazing into firepots as well as scientific and artistic glassworkers who are doing work with clear borosilicate only. The AGW^®-300 is a one-piece, non-laminated filter with the same transmission characteristics of our original AGW^®-186 laminated filter. The filter has very good 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 high amounts of infrared radiation.

Lenses are available in plano (non-prescription) and single vision prescriptions only.

Specifications:

Maximum Visible Light Transmission: 77.6 %
Average (400 to 750 nm) Visible Light Transmission: 60.0% %
Average (751 to 3000 nm) IR Transmission: 3 %

NOTE: This lens should not be used with colored borosilicate and/or fuming. It does not provide sufficient color flare filtration. You must use additional filtration such as our 7520 Clip-on Flip-up.
