AGL (조명용 비구면 콘덴서 렌즈)
  • AGL (조명용 비구면 콘덴서 렌즈)
  • 조명용 비구면 콘덴서 렌즈는 조명용의 빛을 큰 발산각(집속각)으로 조사할 수 있습니다. 고배율의 현미경의 조명계나 발산광원의 빛을 효율적으로 모으는 광학계에 사용됩니다.
Attention

▶When the parallel light is incident from the rear (side of plane or large spherical curvature), spherical aberration will not condense into a large point.
▶Aspheric condenser lens is used for illumination light source. It is not aberration-free for laser focusing.
▶Since the anti-reflection coating is not applied with the lens, the transmittance is about 90% due to the loss reflection of the front and rear surfaces of the lens.
