Reflective Microscope Objective 5mm Focal Length 40X

OBLR-40A

Skip to the beginning of the images gallery

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.

Details

◦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.

Name	Reflective Microscope Objective 5mm Focal Length 40X
Weight	0.5160kgs
Standard Coatings Available	No
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. WEB Reference Catalog Code/W4024
Remark	-
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%)
