□ Equipped with 5X-50X professional infrared objective lenses, providing aberration correction from visible to near infrared wavelengths, suitable for conventional bright field and specialized infrared observation.
□ For high magnification numerical objective lenses with larger aperture, a correction ring is added, which can correct the aberration caused by the difference in thickness of the cover sheet, realizing high-definition and accurate detection in the near infrared wavelength band.
