3x afocal attachment

H-3 Afocal Attachment allows to form a magnified image for better object observation. This attachment is used with JSC Katod Night Vision Devices over existing 1x Objective lens and magnifies the view by 3x (thus the field of view reduces from 40 to 10—11 Degrees). Such accessory is extremely useful in field conditions when the user needs to change the lenses rapidly without threading off the current lens. The attachment is filled with nitrogen, waterproof and fogproof.
