DQPro 16-bit TE-Cooled Fiber Optic Spectrometer_OC

Introduction

DQPro is a deeply TE-cooled fiber optic spectrometer with a cooling temperature down to -25 ℃. It features a compact structural design and a configurable spectral range. The spectrometer offers high resolution, reaching up to 0.1 nm, and low stray light of approximately ~0.5%. With excellent spectral response stability and reproducibility, it is well suited for a wide range of industrial on-site measurements, including laser measurement, plasma emission spectroscopy, color measurement, absorbance measurement, and Raman measurement.

Features

Cooling temperature down to -25 ℃, featuring extremely low readout dark noise and excellent stability.
Compatible with multi-core densely packed fiber bundles, with fiber insertion/extraction strength consistency ≤7%.
Wide dynamic range, high signal-to-noise ratio, and superior stability.

Pixel configuration can be customized according to customer requirements as 2048×128 or 2048×256 pixels. CCD readout noise: measured as the root mean square (RMS) value at the minimum integration time. CCD dynamic range: under minimum integration time conditions, calculated as (saturation value – dark noise baseline) / standard deviation of CCD readout noise; evaluation method follows Oceanhood Taiwan’s standard. Dynamic range (full signal) is evaluated according to the CCD manufacturer’s specifications and industry-recognized standards. Signal-to-noise ratio (SNR) evaluation and calculation are performed in accordance with Oceanhood Taiwan’s standard rating method. Response nonlinearity is measured prior to calibration.
