The best technological choices:<br />
Smart electronic design<br />
• New electronic board design<br />
• Only one control card<br />
• Fewer contactors, fewer<br />
connectors<br />
• Less background noise<br />
• Higher energy output<br />
Compact & High Perf. Mono chro mator<br />
• New design with small footprint<br />
• Holographic concave with 1200 lines/mm<br />

Halogen and Deuterium Lamps<br />
• Preadjusted lamps, no tools<br />
required for replacement or<br />
adjustment<br />
• Very continuous signal<br />
over wavelength<br />
for spectrum scanning<br />
efficiency<br />
Large Cell Compartment<br />
• More space for accessories<br />
settings<br />

Mono chro mator<br />
1200 l/mm<br />
holographic concave<br />
grating:<br />
• High energy<br />
• Low stray light<br />
Light Beam Chopper<br />
• Gives fixed light frequency<br />
• Eliminates stray light from<br />
other sources<br />
5 nm for the best energy, 2 nm for high-resolution applications<br />
For the best performances<br />
Linearity 0.99 % up to 3 Abs @ 250 nm and 540 nm<br />
