Optic Design and specifications
Straight forward optical design from fluorescence microscopy resulting in
- Robustness
- High selectivity
- High aperture (light collection)
= Prerequisites for highest sensitivity
Excitation
- Two solid-state lasers (standard)
- 532 nm and 635 nm for Cy3, Cy5 and similar fluorescence labels
- Peltier-cooled laser modules for enhanced signal stability
- Compact and long lifetime due to solid-state technology
Emission
- Up to 6 emission filters
- Easy filter exchange with motorized filter wheel
- Standard 580 and 680 nm bandpath (for Cy3, Cy5 and similar fluorescence labels)
- Greyfilter for barcode reading (1D- and 2D- barcodes)
- Other emission filters upon request
Detection
- Low-noise Photomultiplier with highest sensitivity for optimal 'Signal-to-Noise'
- “Quantum efficiency-independent PMT-gain control” (proprietary DITABIS-Design)
- 16-bit dynamic range
- Linear over 4 decades
- Two data channels for up to 20-bit dynamics in one run (proprietary DITABIS-Design)
Scanning
Triaxial, motor X/Y/Z-Scan mechanics
- Pixel resolution adjustable 10 to 100µm
- Automatic focus adjustment
- One wavelength per scan for lowest crosstalk (Cy5 vs. Cy3-scan)
Flexibility
- Scanning up to four slides simultaneously
„Force-free“ loading of slides
ISO Slide Standard
- Min. width: 24.9 mm
- Max. width: 25.4 mm
- Length: 75-76 mm
- Scanning field: 23 x 76 mm
- Glass- or plastic slides (e.g. GBO-HTA)
