Excitation Sources

Choice of:

• 450 W xenon short-arc lamp housing with off axis ellipsoidal collector and optional pulsed xenon lamp enhancement (for time resolved phosphorescence)
• 75 W xenon PowerArcTM lamp housing with enveloping ellipsoidal collector.

Note: The Sensitivity Specification listed below is the same with either the 450 W xenon or the 75 W xenon due to the enhanced collection efficiency of the PowerArc!

Excitation Monochromators

Choice of:

• 180 mm Czerny-Turner monochromator with kinematic gratings and all-reflective optics in either single or double

monochromator configuration (the 360 mm focal length double monochromator is recommended for the highest stray-light rejection and sensitivity).

• iHR320 triple-grating turret 320 mm spectrometer with one or two entrance ports.

Note:Specifications hereare basedon 180mm monochromator withstandard 1200grooves/mm gratingblazed at 330nm. Othergratings areavailable.

• Symphony CCD, 1024 x 256 pixels, LN-cooled

Optional T-Side Emission Monochromator for Single Channel Detectors

Specifications are the same as excitation monochromator above1

Single Channel Detectors

Choice of:

• Room temperature PMT housing with R928 (185 to 850 nm) or R13456 (185 to 950 nm)
