Reflective Microscope Objective
These reflective Microscope objective lenses are optimized for chromatic aberration over a bandwidth of 350nm to 7um. They are mainly used in microscope-spectrometry and failure analysis in the semiconductor industry.
Adjustable for use with various types of microscope tubes with focal length ranging from 80mm to infinite
The reflection mirror is strengthened with aluminium coating and MgF2 protective layer.
The RMS (M20.32 P0.706) mounting thread conforms to JIS standard and is compatible with all major microscope tubes.
The focus point and image size of visible, UV and IR wavelengths shows no difference and precise matching of the images is possible.
