Glass Shaping Tools and Accessories
Small or Large Safety Plastic frames and includes the pictured case and glasses holder.
The large frames fit over most personal eye glasses.
AV 2000 filters out more of the sodium flare than ordinary didymium filters, while enhancing the blue, green and red spectrums. The Red colour spectrum is particularly valuable when judging the temperature of glass by its amount of red glow. Additionally, AV 2000 filters out most ultraviolet and considerably more of infrared than didymium lenses.
The clip-ons come in various styles and sizes. The frames are metal with glass lenses (economy lenses above have plastic lenses). Very high quality.
