61-6949-34 Near Infrared Achromatic Lens Focal Length: 50.2mm DL-15-50PNIR

特徴

  • By combining two lenses with different refractive index wavelength dispersion into a single lens, chromatic aberration and spherical aberration can be reduced compared to a single spherical lens.
  • It can be used as a condenser lens for near infrared LD or YAG laser (1064 nm).
  • Optimization by lens design results in little change in focal length in the near infrared.
  • The focal lengths of 700 nm, 880 nm, and 1100 nm match and are optimized to minimize aberration.
  • Since not only chromatic aberration but also spherical aberration is well corrected, it is ideal as a collimating lens for laser.
  • It is corrected not only for aberrations of the on-axis object point, but also for off-axis coma and astigmatism.
  • Air gap type condensing lens (NYTL/NYDL) for laser processing is also available.
  • * Use an achromatic lens when you want to focus an image at infinity or when you want to use a point light source that is parallel to the image.
  • Sufficient optical performance cannot be obtained when the camera is used for close-range imaging.
  • * The chromatic lens has an orientation that allows parallel light to enter the lens.
  • * This function allows parallel light to enter from the side of the face with a small radius of curvature (the face pointed to by the arrow).
  • * When parallel light is incident from the opposite side, chromatic aberration and spherical aberration occur, and the condensing spot becomes larger.
  • Chromatic aberration and spherical aberration increase when the camera is used in the visible range. Also, the transparency may be poor.
