VPF-S (간섭필터)
  • VPF-S (간섭필터)
  • 45mm이상의 큰 유효경으로 사용가능한 대역 통과 필터 입니다. 대역 통과 필터를 통과한 두꺼운 콜리메이터 빛을 시료에 집광시키고 싶을 때나 한점에서 발산하는 빛을 조준해서 유효경이 큰 대역 통과 필터를 통과시키고 싶을 경우에 사용합니다.

▶Heatproof temperature at 80°C (Celsius) as maximum, please avoid using it to high temperature light-source.
▶The filters are heat absorptive, therefore they are not fit to use with high power laser and high energy pulsed laser.
▶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 experiment.
▶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.
