VPF-C(214.0nm~647.1nm/간섭필터)
  • VPF-C(214.0nm~647.1nm/간섭필터)
  • 1nm에서 40nm까지의 스펙트럼 폭(반직폭)로, 지정파장만을 투과시키는 필터입니다. 휘선램프에서 특정 스펙트럼만을 골라낼 경우나, 다파장발진하는 레이저에서 특정 파장만을 골라낼 경우에 사용합니다.

▶The filters characteristic depends on the angle of incident. If the angle of the light axis inclines, the center wavelength switch to short-wavelength side and the transmittance may decrease too. More the selected spectrum width is precise more the inclination tolerance is small. Make sure that the incident angle is set at 0 degree for an efficient xperiment.
▶The filters usage temperature of environment is set at 23℃ (Celsius), more the temperature is high more the center wavelength switch to the long-wavelength side.
▶Therefore a high precision set up is required for obtaining an efficient experiment each filter thickness is different.
▶Interference filters are heat absorptive, therefore they are not fit to use with high power laser and high energy pulsed laser.
