Diverging Objectives for High Powers

The microscope objectives are intended for beam expansion without focus. They consist of two lenses made from synthetic fused silica which are air spaced and thus can be used even for the highest laser powers. The objectives are not achromatic.

The microscope objectives are particularly suited for focusing of laser beams (e.g. in a spatial filter). Objectives contain an achromatic doublet lens with air gap, making them suitable for high laser powers. Compatible with standard microscope mounts (RMS). Lenses are coated with broadband antireflection layers for the visible spectral range.
