WDF reflection monochromator

First, WDF reflection monochromator experiment content:

1. Understand the structure principle of reflective prism monochromator;

2, master the monochromator calibration and use methods;

3, the use of monochromator to measure the spectral transmittance of the filter.

Two, the main technical parameters:

1. The instrument is composed of incident collimation system, dispersion system and exit concentrating system;

2, wavelength: prism: 400-706.5nm, wavelength accuracy: 1nm;

3, resolution: R=982 can be separated sodium D double line (0.6nm);

4, the monochromatic degree of the instrument (for sodium D line) : when the slit is 0.1mm wide △λ≤5nm;

5, when the slit is infinitely narrow: △λ≤0.6nm;

6, reflecting spherical objective: focal length (f) = 344.4mm;

7, the relative aperture (D/F) ≈1:7;

8, slit working characteristics: working range: 0 ~ 3mm;

9, reading drum value: 0.01mm;

* 10, high pressure mercury lamp power supply (inductance) : The heat dissipation hole distance of 45° on both sides of the case shell is ø3*15*18, the surface sand black process has no noise and good stability. No fuse, with short circuit protection device;

11, optical triangle guide rail (cast iron) 1 m;

12, double glued lens group: F: 150mm, ø40mm;

※13, with the support made of plexiglass plate spectrum line table.

14, fused quartz prism wavelength: 185.4-3200nm (optional)
