AGL-15/AGL-20 (비구면평면 볼록렌즈)
  • AGL-15/AGL-20 (비구면평면 볼록렌즈)
  • 조명용 비구면 콘덴서 렌즈는 조명용의 빛을 큰 발산각(집속각)으로 조명할 수 있습니다. 고배율의 현미경의 조명계나 발산광원의 빛을 효율적으로 모으는 광학계에 사용됩니다.
Attention

▶When input the parallel light from the back surface (flat), the spherical aberration is not condensed on one point largely.
▶Since an aspheric plano convex lens is a single lens, the focal length will change depending on the wavelength.
▶Since there is not the anti-reflection coating on the lens, by the reflection loss of the front surface and the back surface, the transmittance is 90% or less.
