The goal was to design an instrument that would provide the most precise examination with exceptional comfort. With a weight of 110 g and precision HEINE optics with LED HQ illumination for crisp, high resolution images, the SIGMA250 exceeds our initial goals. Endless flexibility and compact design: The new, high performance power source HEINE mPack mini offers freedom from cables that tie the users to desk, wall or static power sources. With a weight of just 95 g and dimensions of 44 x 23 x 101 mm, this mobile power source is now approximately approx. 70 % smaller and lighter than its predecessor.
