Optical practices, dispensing opticians, optometry practices, and ophthalmology clinics use the LM-600P wherever spectacles are checked with the wearer present. At the dispensing counter,r it confirms a finished pair against the prescription before it is collected, and in pre-test it reads the patient's current spectacles before the eye examination. Contact lenses are checked on the same instrument, on the dedicated nosepiece supplied with it.
The wearer's experience is where the LM-600P earns its place. A reading can take as little as 0.09 seconds, the lens type is detected without any choice from the operator, and the thermal printer cuts a 58 mm printout that can go home with the patient. Tinted and sun lenses that pass 10% of light or more can be read too, so a wearer's tinted pairs can be checked in the same visit. On the UV version, two lenses' UV-A results appear side by side, which helps explain the protection a pair gives.
For the practice, the details serve the same visit. Ink dots stay clear on lenses with a water-repellent coating, so newly coated lenses can be marked for fitting, and a prism layout function supports lenses prescribed with prism. Green light at 535 nm gives precise values on high-index lenses, with an Abbe number from 20 to 60 available when wanted. Readings can travel onward through RS-232C, USB or an optional Eye Care card, which carries them from pre-test to the refraction room.
At 3.9 kg and 194 mm wide, the instrument fits a dispensing counter or a pre-test bench, and it runs on any mains supply from 100 to 240 V.
