SLCFU (불화칼슘 평면 볼록렌즈)
  • SLCFU (불화칼슘 평면 볼록렌즈)
  • 불화칼슘(CaF₂)는 자외(200nm)에서 근적외(8μm)의 넓은 파장역에서 뛰어난 투과특성을 가진 결정입니다. 이 CaF₂를 사용한 평면오목렌즈입니다.

▶It may be broken and be cleavaged by a sudden temperature change and shock. CaF2 has low hardness and scratch upon contact with a metal and glass. Please use very carefully.
▶There is not the anti-reflection coating on the surfaces. By the loss of surface reflection (3% per surface), the transmittance is about 94%.
