Outstanding Sensitivity and Linear Dynamic Range
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
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.
