Rapid heating at approximately 50°C/sec using focused light heating method, with the possibility of rapid cooling when the heating lamp is turned off. Compatible with various atmospheres.

【Other Features】 ○ The emitted infrared radiation light is efficiently reflected and concentrated, further enhancing high heating capability. ○ With a low heat capacity heating lamp and a cooled high-reflectivity mirror, the furnace's heat capacity is minimal, allowing for rapid heating and cooling. ○ Due to its vacuum airtight structure (patent pending), direct radiation heating is possible, enabling clean and rapid heating and cooling. ○ High-temperature microscopic observation can be easily performed. 【Product Lineup】 ○ IR-HP (6 Parabolic Surface Radiation) → Rapid heating and cooling from six directions significantly expands the temperature distribution area compared to conventional heating furnaces. ○ IR-QP (4 Elliptical Shared Concentration) → Rapid heating and cooling from four directions doubles the temperature distribution area and rapid heating compared to conventional heating furnaces. ○ IR-TP (2 Elliptical Shared) → Rapid heating and cooling from two directions enables microscopic observation compared to conventional heating furnaces. ● For more details, please contact us or refer to the catalog.
