METICULAB Square Quartz Optical Cell for Spectroscopy
Square Quartz Optical Cell For Spectroscopy And Custom Research
Brand: METICULAB
Model Number: MTC-OPT-SQ01 (Custom series)
Product Description
The Square Quartz Optical Cell from METICULAB is a high‑precision absorption cell designed for UV‑Vis‑NIR spectroscopy, optical gas analysis, fluorescence measurements, and custom research applications. Fabricated
from high‑purity JGS1 far UV quartz glass (≥99.9% SiO₂), each cell provides ≥82% transmittance across 200‑2500 nm with an empty cell. All optical windows are double‑side precision polished to λ/10 flatness (≥λ/8) and 40/20 scratch‑dig (Ra ≤0.5
nm), ensuring minimal stray light scattering and accurate photometric data.
The cell is fusion‑sealed using high‑temperature glass bonding technology, guaranteeing no adhesive degradation or leakage over time. Standard configuration features two polished windows for straight‑through optical path (transmission/absorbance);
four‑way windows (360° illumination) are available for fluorescence or Raman spectroscopy applications.
Applications cover TDLAS gas sensors, FTIR spectrometers, UV‑Vis spectrophotometer absorption cells, fluorescence quartz cuvettes for dye or quantum dot analysis, flow‑through liquid cells for chemical reactors, and general teaching or R&D environments.
