Both Episcopic and Diascopic Illumination
A built-in 12V/100W halogen lamp light source, aperture diaphragm and LWD condenser give you the option of doing diascopic (transmitted light) observation as well as episcopic (reflected light) observation.
CFI60 LU/L Infinity Optical System
The L200 series of microscopes incorporate CFI60 LU/L Infinity Optics providing images with excellent clarity, high contrast and a minimum of flare.
Rigid, Stable Design
Using CAE (Computer Aided Engineering) Nikon has dramatically increased the rigidity of the L200 series making them extremely stable and resistant to vibration.
ESD Design
The bodies of these microscopes are finished with an ESD (electrostatic discharge) coating to prevent particles from adhering. The built-in motorized nosepiece uses a shielded center-motor that traps foreign particles inside, preventing them from falling onto the sample.
Tilting Trinocular Eyepiece Tube
The Tilting Trinocular Eyepiece Tube allows continuous adjustment of the tilt angle from 0-30 degrees.
Improved Illumination System
A new illumination system improves signal/background ratio and the sensitivity of these microscopes under darkfield observations to detect minute scratches and surface irregularities within the sample.
Focus Target
The addition of a focus target that easily moves in and out of the optical path allows for easier focusing on bright samples such as bare wafers.
Wafer Loading Compatability
The L200D has been designed to work with the NWL860 series wafer loaders.
