HEINE SIGMA® 250 Binocular Indirect Ophthalmoscope

Spectacle-mounted Ophthalmoscope – with LEDHQ illumination

The spectacle-mounted indirect Ophthalmoscope to suit any pupil size. Two separate controls for selecting the ideal setting of parallax and convergence guarantee completely illuminated stereo views in pupils up to 2 mm, as well as viewing in the periphery. The illumination beam can be adjusted by ±3º to eliminate reflexes.

  • NEW: Power Source mPack mini – compact and light power source with USB charging option. With a weight of just 95 g and dimensions of 44 x 23 x 101 mm, this mobile power source is now approx. 70 % smaller and lighter than its predecessor. Typ. 11 hours in continuous operation at maximum power. Please note: The SIGMA 250 is still compatible only with mPack mini.
  • Extremely light, 110 g without frame. Light and comfortable.
  • LED in HQ: The new standard in LED illumination defining optimal light intensity, homogeneity and colour rendering for the most accurate diagnosis. Red is red, blue is blue. Colour temperature: 4,500 K, Colour Rendering Index (CRI) > 90, special index for red colours (R9) > 75 on a maximum scale of 100.
  • Carbon fiber frame. Perfect combination of durability and light weight.
  • Illumination beam adjustable ± 3°. Eliminates reflexes.
  • Integrated red-free filter. Improves contrast.
  • Detachable blue and yellow filters. For Fluorescence Angioscopy.
  • Large and small apertures.
  • Dust proof. Maintenance-free.
  • PD selection from 47 to 72 mm. Suits any user.
  • Optics on swivel mount. Unrestricted view.
  • Optional clip-in correction frame for prescription lenses.

HEINE SIGMA 250 Adjustment

Synchronized Convergence and Parallax Adjustment System

The advanced One-Step Small and Variable Pupil Control maximizes stereopsis in dilated pupils and allows for the instant adjustment of the optical system to ensure fully illuminated, stereoscopic views through pupils as small as 1 mm in diameter.

  • Dilated Pupil. In the case of a dilated pupil, the HEINE Synchronized Convergence and Parallax Adjustment System adjusts the left and right observation paths as far apart as possible (large angle of convergence) providing for maximum stereopsis (depth perception). The illumination beam is automatically positioned as high as possible relative to the observation plane (creating a large angle of parallax) in order to maximise illumination and minimise unwanted reflections [01].
  • Undilated Pupils and viewing in the Periphery. In cases of pupils that can not, or should not be dilated, a binocular view with full illumination is not possible without adjustments of the optical system[02]. By adjusting the Small and Variable Pupil Control Lever located on the bottom of the OMEGA Series instruments, the angle of convergence between left and right observation paths is reduced and the angle of parallax (light path) is automatically reduced in one, simple step. The observer can now enjoy a fully illuminated, binocular view with excellent stereopsis [03] even through a pupil as small as 1 mm in diameter, or in cases where the pupil appears as an ellipse as a result of viewing the periphery.
