The FP-8550 has been designed for demanding research applications and has the same functionality and advantages of the FP-8350, but also includes an optimized optical design for very low stray-light and enhanced spectral purity. Combined with the most thorough spectral correction, material engineers and researchers are assured of accurate measurements for the evaluation of advanced materials. The FP-8550 performs with the highest sensitivity for fast measurement of samples with low level fluorescence, whether they are challenging biochemical systems or low quantum efficiency materials. High-speed scanning of phosphorescent samples and 3D spectra enable fast acquisition of high-quality, high-density data.
The FP-8550 optical bench has been developed to take advantage of the wide range of sampling accessories and applications, such as temperature-dependent melting and kinetics, anisotropy, FRET, spectral correction, and quantum yields.

The high-throughput optical system and low noise signal processing of the FP-8050 series results in an extremely high signal-to-noise (S/N) performance up to 8,500:1 (RMS). In addition, the FP-8050 series has been enhanced to provide up to 7 orders of magnitude of linear dynamic range. As shown in the calibration curve for fluorescein, there is excellent linearity even for samples at very low concentrations.

Higher-Order Light Cut-Off Filters
In order to remove peaks originating from higher-order diffracted light, cut-off filters appropriate to the measurement wavelength should be used. The FP-8050 Series (excl. FP-8250) include cut-off filters that are matched to the wavelength range and switched automatically

Accurate Spectral Correction
Spectral correction should be made to any fluorometer that is used for defining accurate spectral data. All models in the FP-8050 Series can be spectrally corrected with a simple procedure that uses a range of calibration standards, including broad-spectrum standard light sources and Rhodamine B.
Auto Adjustment of Detector Gain and Sensitivity
The FP-8050 Series includes both Auto-Gain and Auto-Sensitivity Control System (SCS), which automatically adjust the detector gain and sensitivity for optimum measurement. Auto-Gain automatically adjusts the gain of the signal from the detector so that the S/N is optimized throughout the entire scan range for spectral measurement, and weak fluorescence spectral peak shapes can be observed against scattered light with a high S/N. The Auto-SCS allows the user to create calibration curves for a wide concentration range without having to manually change the instrument sensitivity settings.

Automatic Band-Pass Filter for Higher-Order Diffraction
The automatic band-pass filters remove peaks originating from higher-order diffracted light fr artifact-free spectral acquisition and analysis. The band-pass filters can also be used for spectral corrections, 3D measurements and quantum yield determination.
Automatic Accessory Recognition
Accessories are automatically recognized when installed in the instrument. Spectra Manager™ logs the accessory name and serial number; this information is saved in the data file for a complete record of the measurement.
Long-Life Light Source
Continuous output xenon arc lamps offer the greatest sensitivity. For the longest and highest performance, the FP-8050 series now includes a newly designed Xe arc lamp with prolonged lifetime. This new light source can be used up to 3x longer than previous lamps (maximum operating time: approximately 3000 hours), with long-term stable measurements, reduced maintenance and lower running costs.
Daily Monitoring of Instrument Performance
Validation program The Validation program includes a full suite of tests to validate the total instrument performance. When executed, simple prompts guide the user on how to perform the tests. All instruments in the FP-8050 series include a mercury lamp as standard for wavelength calibration.
Daily Check program
The Daily Check is a less comprehensive performance check can be made at any time for continuous performance monitoring. After starting the Daily Check program, a timer is activated, and sample measurement is executed automatically after a predetermined stabilization time. The results are collated over time and a batch display lets the user review the ongoing performance of their instrument.
Instrument Activity Log
The instrument activity log is a useful alternative to the paper log books found in multi-user facilities. A record is maintained of user, duration of operation and lamp usage.
