Neitz has poured its 50 years of medical optics expertise into the NSI-III to produce a versatile, high-powered illuminator for ophthalmic examinations or surgical operations with the BL line of loupes. The NSI-III achieves the perfect combination of adaptability and affordability without sacrificing quality.
