  • A bright idea for the operating room
    . Reflectors injection-molded from Ultem 1000 PIE, in combination with aluminum metallization, produce what's called a cold mirror -- it directs visible light downward while radiating infrared heat upward toward the top of the lamp and away from the patient. Another benefit of Ultem PIE is its ability
