Description

  • Wavelengths: 257 nm, 266 nm, 343 nm, 355 nm, 515 nm, 532 nm, 1030 nm, 1064 nm
  • Focal length: 200 mm
  • Entrance pupil: φ 11.0 mm
  • Image field size: φ 24.0 mm
  • Weight: 0.055 kg

Guide:

  • Compatible with infinity-corrected objectives.
  • Specified magnifications cannot be obtained when using with Olympus objectives.
  • External M32 x 0.5 threading.

Attention:

  • Please use with infinity-corrected objectives. They are not compatible with finite conjugate objectives.
  • These tube lenses must be used by inputting collimated light from the end without threading. Inputting collimated beam from the threaded end results in large focusing spot size and blurred image due to large chromatic and spherical aberration.
  • Operating at unspecified wavelengths might result in large aberration and low transmittance.
