- Transmission and reflection mode bright field imaging
- Motorized condenser module
- Magnifications for imaging:
- - 5x, 10x, 20x and 50x.
- - Eye piece gives 10x magnification.
- - Additionally, 1.6 x (pre-installed in the microscope)
- - Highest magnification possible: 800x
- Conoscopy module (for imaging the back focal plane of objective lens) with in-built Bertrand lens
- Removable polarizer and analyzer in both transmission and reflection geometries.
- Calibrated rotational sample stage with a resolution: 0.1o with vernier scale
- Aperture control for incident light, and transmitted / reflected light from the sample
- Simultaneous visual and imaging option.
- Polarizer and analyzer can be independently rotated by 360 o
- Provision to insert filters (2.5 cm dia) in the light path
- Z-axis positioning with coarse/ fine movement with a vertical resolution of 2 μm.
- X-Y direction movement: 40 mm x 40 mm with a resolution: 0.1 mm
- Replaceable light source; for. eg. Hg vapour lamp with compatible dimensions
- Imaging:
- - CCD camera (Leica- DFC 420C): 5 MP sensor; Image capture rate: 15 fps max; Peltier cooling.
- - Image acquisition software: Leica Application Suite (LAS)
- - Direct control of the microscope with LAS for intensity& aperture control and automatic scaling of captured images.
- - Image correction during live imaging for eg: hue, gamma and brightness control.
- - Image formats: tiff, jpeg, png and bitmap.
- Temperature controller:
- Hot stage: Mettler Toledo HS82 with Controller HS1
