To the product series

  • Compact design: Ø 29 mm diameter compatible with camera size; lens total length < 42 mm
  • High resolution: Full FOV resolution up to 230 lp/mm; compatible with cameras of pixel size ≥ 2.2 µm and sensor format ≤ 2/3"(Ø 11 mm)
  • Wide spectrum range: 400–1,000 nm optical coating spectrum; compatible with VIS and NIR band
  • Low distortion: TV distortion < 0.2 %
  • High Relative Illumination: Chief ray angle < 5°. Matching with cameras enables to realize high evenness image.
