- A versatile microscope head typically used as an OEM product suitable for fitting to specialist machines, such as those designed for inspection and repair of semiconductor wafers using YAG (near-infrared, visible, near-ultraviolet, or ultraviolet) lasers.
- Compact microscope unit equipped with an eyepiece observation section.
- Usable in infrared optical systems. Applications: internal observation of silicon systems; spectral charateristics analysis using infrared.
- The inward facing turret and long working distance objective lenses maintain the high operability of the microscope.
