The retina lens is a crucial optical tool in ophthalmic diagnosis, used in indirect ophthalmoscopes or slit lamp microscopes for examinations. Through a high light-transmitting design and specific refractive power, it provides wide-angle, high-resolution fundus imaging for doctors, covering the retina, optic nerve, and macular area.
Optical performance optimization: High light transmittance, low distortion.
Disinfection and Safety: Tolerance to Alcohol and Hydrogen Peroxide Disinfection.
