Sigma Optics Reflective Objective

The adjustment ring installed in the center of the lens barrel can be used to change the length of the lens barrel. By adjusting, it can be used for various microscope tubes ranging from 80mm to infinity in length.
Due to the MgF2 protective film on the aluminum film of the reflector, it is not easily aged and can be used for a long time.
◦objective lensThe installation thread adopts JIS standard M20.32 (P=0.706), which can be installed on many microscope barrels.
Due to the fact that there is no difference in the focal position or image size between visible light, ultraviolet light, and infrared light, the image of invisible light and the image of visible light can accurately overlap.

▶ We also undertake the manufacturing of aluminum free protective film coatings that can be expanded to vacuum ultraviolet wavelengths, or objective lenses with gold-plated films from near-infrared to far-infrared.
▶ There is also an adapter (OBLR-AMT) available for installation on the microscope converter. Please confirm with our company or microscope manufacturer if it is possible to install the adapter and reflective objective on the converter.
▶ There is also a fixed bracket (LHO-20.32) that can fix the reflective objective lens.

▶ Due to the obstruction of light near the optical axis by the reflective mirror, it cannot be used for laser processing.
▶ Depending on the microscope, some converters cannot be equipped with reflective objectives.
▶ The thickness scale ring of the cover glass cannot be adjusted. Please make the length scale of the barrel length adjustment ring point to the scale position of the thickness of the cover glass used.
▶ Due to the obstruction of light near the optical axis by the reflective mirror, when using a directional light source for observation, the received light amount may become extremely small or observation may not be possible.
▶ Due to the obstruction of the reflector (about 36%) or the reflectivity of the aluminum film (about 90%/1 surface), there will be a loss of more than 45% of light.
