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 here are based on 180 mm monochromator with standard 1200 grooves/mm grating blazed at 330 nm. Other gratings are available.

Resolution: 0.2 nm

Accuracy

0.5 nm

Speed

150 nm/s

Range

0–1300 nm mechanical range; throughput based on grating’s blaze

Bandpass

Set automatically (0–30 nm single-grating, 0–15 nm double-grating)

Sample Compartment

All reflective optics sample compartment with single cuvette sample compartment tray for quick replacement with variety of optional sample hold- ers. Reference photodiode for excitation correction from 240–1000 nm. Optional front-face detection for highly turbid samples in solution. Optional T-Format detection to allow optional second emission-detection channel.

Emission Imaging Spectrograph

iHR320, for multi-channel acquisition, with triple-grating turret. Can be configured with one or two exit ports each for multi-channel or single channel detectors. Equipped with 150 grooves/mm grating for multi-channel detection of entire emission spectra with a single acquisition.

Resolution

0.2 nm

Accuracy

0.3 nm

Range

0–1500 nm mechanical range (using a 1200 grooves/mm grating and single channel detector)

Multichannel Detectors

Choice of up to two of the following:

• SymphonyTM IGA, 512 pixels, 800 to 1,700 nm, LN-cooled
• Symphony Extended IGA, 512 pixels, 1,100 to 2,200 nm, LN-cooled
• SyncerityTM CCD, 1024 x 256 pixels, TE-cooled (-60oC)
• Synapse PlusTM CCD, 1024 x 256 pixels, 200 to 1,100 nm, TE-cooled (-80 oC)
• 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)
• TE-cooled PMT housing with R2658 (185 to 1,050 nm)
• TE-cooled PMT housing with H10330-45 (950 to 1,400 nm) or H10330-75 (950 to 1,700 nm)
• LN-cooled PMT housing with R5509-43 (300 to 1,400 nm) or R5509-73 (300 to 1,700 nm)
• LN-cooled IGA (1.7) detector, 800 to 1,550 nm
• LN-cooled extended IGA(1.9) detector, 1,000 to 1,750 nm
• LN-cooled extended IGA(2.1) detector, 1,000 to 2,000 nm
• LN-cooled extended IGA(2.6) detector, 1,000 to 2,400 nm
