Clear Transparent Optical Glass Lens Customized Shape Available 0.02mm Size
Optical Glass lenses are very common type of viewer lenses,they consist of two or more lense elements,which have been corrected for chromatic aberration with
respect to two selected wavelengths,the elements must be fixed in relation to one another by either mounting or cement.
Achromatic lenses are designed to specifically function within the infrared,visible,or ultra-violet wavelength ranges,and they are not symmetric devices.
