Prevention of destruction due to rapid heating and cooling! Glass filter that absorbs heat rays.
The "heat ray absorption filter" is a somewhat bluish filter glass that has a high transmittance in the visible range and absorbs heat rays (infrared rays). "HA-30" and "HA-50" are phosphate glasses that absorb heat rays emitted from light sources very well, making them particularly effective for slide projectors and various lighting fixtures. To prevent the breakage of filter glass due to rapid heating and cooling, we can also supply tempered glass using thermal strengthening methods. 【Features】 ■ High transmittance in the visible range and absorbs heat rays (infrared rays) ■ Used in slide projectors and various lighting fixtures ■ Prevents breakage due to rapid heating and cooling ■ Tempered glass can also be supplied *For more details, please refer to the PDF materials or feel free to contact us.
