Microscope Objectives

Microscope Objectives

For close inspection of small components using infrared imagery, Janos has designed a line of microscope objectives for mid-wave thermal imagers. The line includes magnifications of 1x, 2.5x, 4x, and 5x. The front objective section is interchangeable with the same “eyepiece” that mounts to the camera. Every effort was made to maximize the distance from the lens to the object being inspected. These lenses interface with the bayonet mount.
