Fluorescence instrument teaching skeleton

荧光仪器教学骨架

Explore a static 3D optical bench, grating-driven monochromators, and a simplified synthetic trace.

从激发单色器、样品池、90° 发射收集到检测输出,用一个克制的教学骨架理解荧光分光光度计的工作链路。

Conceptual model only. Not real instrument control. Not calibrated measurement.
仅为概念模型,不是真实仪器控制,也不是校准测量。

1. Choose a mode / 选择模式 Pick a scan channel. 选择扫描模式,先看哪一路通道在变化。

2. Move one control / 移动控制项 Watch the trace respond. 移动一个控制项,观察合成谱线如何响应。

3. Inspect a mono / 查看单色器 Click Ex or Em mono, then drag the grating. 点选激发或发射单色器,然后拖动光栅。

Fluorescence spectrophotometer conceptual light path / 荧光分光光度计概念光路 A simplified right-angle layout showing the light source, excitation monochromator, sample cell, emission monochromator, detector, and spectrum output. 简化的 90° 光路布局,展示光源、激发单色器、样品池、发射单色器、检测器和谱图输出。 Light source / 光源 Ex mono / 激发单色器 Sample / 样品池 Em mono / 发射单色器 Detector / 检测器 Spectrum / 谱图 Ex path / 激发光路 90 deg Em arm / 90° 发射臂 90 deg / 90° Fixed / 固定 Scanning / 扫描

Primary path: click Ex mono or Em mono, drag the pale grating face or glowing handle, then watch the split rays, wavelength, beam color, diagnostics, and synthetic spectrum update.
主要路径:点击激发或发射单色器,拖动浅色光栅面或发光手柄,再观察分光线束、波长、光束颜色、诊断和合成谱图同步变化。

Optical path notes / 光路说明 Keep the main view focused; open for geometry caveats. / 保持主视图聚焦,需要时展开几何边界。

Blue excitation axis / 蓝色激发轴 Light reaches the sample through the excitation monochromator; the straight-through residual excitation is shown entering a beam stop, not the detector. 光经激发单色器到达样品;直通方向的剩余激发光进入光束终止器,而不是进入检测器。

Cyan 90° collection arm / 青色 90° 收集臂 Fluorescence is collected from the side path through the emission monochromator before detection. 荧光从侧向路径被收集,经过发射单色器后再进入检测器。

Beam stop / 光束终止器 The straight-through excitation direction enters an absorbing stop, so it is not read as reflected light or detector collection. 直通方向的激发光进入吸收终止块,避免被误解为反射光或检测光路。

Signal output line / 信号输出线 The fine line after the detector represents a processed display signal, not another optical beam. 检测器之后的细线表示处理后的显示信号,不是另一束光。

Controls / 控制面板

Explore the scan model / 探索扫描模型

Mode / 模式
Advanced geometry: detector angle / 高级光路:检测角 Source offset + 80-100 deg detector arm / 光源偏移 + 80-100° 检测臂

Select source in the 3D scene, then drag the blue Z-axis handle for a bounded entrance offset. The sample cell stays fixed in the holder; select detector to reveal the cyan arm handle. These geometry changes affect intensity and diagnostics, not selected wavelength.
在 3D 场景中选择光源,可拖动蓝色 Z 轴手柄做受限入口偏移;样品池固定在样品架中。选择检测器可显示青色检测臂手柄。这些几何变化只影响强度和诊断,不改变选通波长。

Sample cell is fixed in this model, matching the usual cuvette-holder workflow. 样品池在此模型中固定,贴近常见比色皿架的使用方式。

Light source / 光源

Provides broadband or selected excitation energy before the path is shaped by the excitation monochromator. 光源提供宽带或选定的激发能量,随后由激发单色器塑造光路。

Select source in the 3D view, then drag the blue Z-axis handle or use Source offset. Alignment changes intensity, not wavelength. 在 3D 视图中选择光源后,可拖动蓝色 Z 轴手柄或使用光源偏移;对准只改变强度,不改变波长。

Corrections & artifacts / 校正与伪影

Why source spectra are not directly comparable / 为什么谱图不能直接比较

These cards turn trusted instrument guidance into visitor-facing caveats. They are teaching notes, not corrections applied by this website.
这些卡片把可信仪器资料转成访客可读的注意事项;它们是教学说明,不代表本站已执行校正。

Detector response / 检测器响应 Different instruments can reshape the same spectrum. / 不同仪器会改变同一谱图的表观形状。

Detector responsivity and optical throughput vary with wavelength, so uncorrected shapes should be read cautiously. / 检测器响应与光学通量会随波长变化,未校正谱形只能谨慎解读。

Excitation flux / 激发通量 Changing excitation wavelength also changes source power. / 改变激发波长也会改变光源功率。

An excitation scan is not just a material response unless source intensity is accounted for. / 激发扫描若未考虑光源强度变化,就不能只当作材料本身响应。

Slit bandpass / 狭缝带宽 Wider slits trade resolution for signal. / 狭缝变宽会用分辨率换取信号。

The simulator shows this qualitatively; it does not reproduce a certified instrument function. / 模型只定性展示信号与分辨率的取舍,不复现认证仪器函数。

Scatter bands / 散射带 Rayleigh and Raman features can appear in EEMs. / EEM 中可能出现瑞利和拉曼特征。

They are optical artifacts or solvent-related signals, not automatically sample fluorescence peaks. / 它们可能是光学伪影或溶剂相关信号,并不自动等同于样品荧光峰。

Inner-filter effect / 内滤效应 Optically dense samples can suppress or distort fluorescence. / 光学较厚的样品会压低或扭曲荧光。

Absorption and reabsorption can change intensity and apparent shape before any material conclusion. / 吸收与再吸收会先改变强度和表观谱形,不能直接推出材料结论。

Linearity & saturation / 线性与饱和 Too much signal can stop being proportional. / 信号过强时可能不再保持比例关系。

Detector linear range matters for quantitative work; this page avoids quantitative comparison. / 定量工作需要考虑检测器线性范围;本站避免做定量比较。

Reference context / 参考背景: NIST correction standards and USGS fluorescence field guidance. No NIST or USGS data are plotted here. / 本页未绘制 NIST 或 USGS 数据。

Sample & geometry boundaries / 样品与几何边界

The 90° model is useful, but not universal / 90° 模型有用,但并非适用于所有样品

The current bench teaches a common right-angle fluorescence geometry. Real samples may require different geometry, dilution, or correction strategy.
当前光学台用于讲解常见的直角荧光采集;真实样品可能需要不同几何、稀释或校正策略。

Right-angle / 直角采集 Best as the default mental model for clear dilute samples. / 它最适合作为透明稀溶液的默认理解模型。

Excitation passes through the sample, while fluorescence is collected from the side to reduce direct excitation light. / 激发光穿过样品,荧光从侧向采集,以减少直射激发光干扰。

Front-face / 前表面采集 Useful concept for dense, turbid, solid, or surface-like samples. / 对浓稠、浑浊、固体或表面样品更需要考虑这种概念。

This is noted as a boundary only; the current 3D simulator does not implement front-face optics. / 这里只作为边界提示;当前 3D 模型未实现前表面光路。

Sample environment / 样品环境 Solvent, pH, temperature, and quenching can alter fluorescence. / 溶剂、pH、温度和猝灭都会改变荧光表现。

Material interpretation needs sample context; this page only shows cautious examples. / 材料解释需要样品背景;本页只展示谨慎的教学示例。

Future data gate / 后续数据门槛 New material examples need source, license, axes, and claim boundaries. / 新材料示例必须先明确来源、许可、坐标轴和声明边界。

USGS DOM or EVOO EEM subsets are candidates only after provenance review. / USGS DOM 或 EVOO EEM 子集只有经过来源审查后才适合加入。
