Achromat 4 / 0.10 Microscope Objective

This fairly early achromat objective is engraved ‘Zeiss Winkel’ which would indicate a manufacture date shortly after the end of WW2. It is very good condition with a bit of wear to the crowns of the black lacquer on the attachment knurling. The magnification color band (red) is very strong and uniform � unusual for this vintage lens. The glass is in excellent condition.
