◦Chromatic aberration is corrected in the visible range (400 − 700nm).
◦Two types of parfocal distance are available, 45mm and 90mm.
◦This parfocal 95mm lens has a long working distance and a corrected field curvature. Its natural observation image is obtained to the periphery of the visual field.
◦ It is possible to improve the response speed in the driving mechanism of the 45mm parfocal objective lens (SFS-OBL/ SFAI-OBL); with a lightweight auto focusing solution.
