摘要:
To provide a near infrared cutoff filter glass which is excellent in optical properties such that the transmittance of visible light is high, and the transmittance of near infrared light is low. A near infrared cutoff filter glass comprising components of P, F, Al, R (R is at least one member selected from Li, Na and K), R′ (R′ is at least one member selected from Mg, Ca, Sr, Ba and Zn) and Cu, wherein (Cu+/the total amount of Cu)×100[%] is within a range of from 0.01 to 4.0%.
