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.

Guide

▶There is no protective layer in aluminium coating for the vacuum ultra-violet spectrum and gold layer coating for near infrared is available as an option.
▶An adapter for the objective lens turret is available (OBRLR-AMT). Check with our International Sales Division or your microscope manufacturer for compatibility and the use of reflective microscope objective lenses.
▶Specific holder for microscope objective lenses (LHO-20.32) is available. W4024

Attention

▶These objectives are not to be used for laser processing due to light axis shielding of the reflective mirror.
▶ There are microscopes that cannot be used with a turret.
▶ The cover glass is not mobile. Use the adjustable correction collar to adjust the focal length and the cover glass thickness.
▶The center reflective mirror shields the center of the light axis. For direct light experiments, a low intense light in the center is expected.
▶The light intensity loss if expected to be around 45%. (The center mirror shielding 36% and the aluminum reflectivity 90%)
