◦NA 0.1 or below (ETL model NA 0.25) can be focused to the diffraction limit.
◦ No adhesive or heat absorption materials are used to produce these lenses and they show high resistance to ultra-violet light.
◦These are not achromatic corrective but offers correction on spherical and comatic aberration.
