1.3Spectral bandwidth: excitation1 nm；2.5 nm；5 nm；10 nm；20 nm 5档

launch1 nm；2.5 nm；5 nm；10 nm；20 nm；5档

1.4Wavelength indication error: excitation wavelength ±2 nmEmission wavelength ±2 nm；

1.5Wavelength repeatability: excitation wavelength≤1 nmEmission wavelength≤1 nm；

*1.6Signal to Noise Ratio:RMS≥1200:1；RMS（BG）≥15000:1; UseR928Photomultiplier tube test(Testing conditions: Testing time)10min，EXbandwidth5nm；EMbandwidth5nm，PMTgain700V）；

*1.7Visual wavelength feedback function, the external indicator light of the host can provide real-time feedback on the operation status of the grating through color changes (grating operation status indicator light), and provide proof materials;

*1.8Integrated cast aluminum base (optical path stabilizer), all optical components are fixed on the integrated cast aluminum base to ensure the stability and collimation of the instrument's optical components;

*1.9Large capacity sample chamber, with reserved openings on the outside of the chamber for easy coupling of high-power light sources (such as lasers);

*1.10The instrument host and light source (xenon lamp) power switch are two in one, with one click power on/off (to avoid motherboard burnout caused by incorrect switching sequence of the host and power);

*1.11Excitation side spectral correction function: The excitation side uses real-time dynamic subtraction of the background signal of the light source for the entire frequency band;

1.12Maximum wavelength scanning speed30000nm/min，30, 60, 240, 1,200, 2,400, 12,000, 30,000 nm/minSeven adjustable levels;

1.13 Scanning interval:0.2-10.0 nm；
