High-Power Focusing Objective / HPOBL
An air gap type objective lens with a parfocal distance of 45mm that does not use adhesive to bond the lenses. They use synthetic fused silica, which has high transmittance in the UV range, and CaF2 material for UV for lenses. They can be used for focusing and collimating high power lasers.
