Step 1 — Choose

Which spectrometer do you actually need?

Three questions. The answer names the model, shows the manufacturer figures behind it, and hands the choice straight to the port builder and the grating planner.

1. What are you measuring?
2. What matters more?
3. How close is the signal to an intense line?

  • Raman needs enough dispersion to separate bands a few cm⁻¹ apart without starving the detector.
  • 2.29 nm/mm dispersion gives 0.08 nm with a PMT and 0.173 nm on a CCD.
  • At f/4.2 it collects 1× the light of the 320 mm reference.

Also consider Omni-λ500i: Roughly 1.5× the dispersion when bands are still merging.

Stap 2 — Vergelijk

Resolutie of licht. Beide kan niet.

Elk model hier is hetzelfde optische ontwerp met een andere brandpuntsafstand. Langer spreidt het spectrum verder uit, en kost u fotonen.

Imaging corrected spectrometers

Omni-λ Series

Omni-λ Monochromators and Spectrographs

The Czerny-Turner monochromator and spectrograph line the rest of the spectroscopy range is built around, in 200, 320, 500 and 750 mm focal lengths. Every model ships pre-aligned and pre-calibrated, and the 320 mm and longer models take an interchangeable triple grating turret so UV, visible and NIR gratings can be swapped under software control.

Hoe het werkt

Eén ontwerp, twee instrumenten

Licht komt binnen via een spleet, een gebogen spiegel collimeert het, en een tralie scheidt het naar hoek. Een tweede spiegel focusseert het resultaat. Wat aan de uitgang zit bepaalt wat u heeft.

Als monochromator

Een smalle uitgangsspleet laat één golflengteband tegelijk door. Het draaien van de tralie stemt deze af — een scannende, afstembare bron.

Als spectrograaf

Een cameraflens vervangt de uitgangsspleet en het hele gespreide spectrum landt in één keer op een CCD- of sCMOS-array.

De tralie bepaalt het bereik

De brandpuntsafstand bepaalt hoever het spectrum zich spreidt; de tralie bepaalt waar het ligt en hoe efficiënt. Revolvers houden er twee of drie, zodat u van UV naar NIR schakelt zonder het instrument te openen.
