Sharp 2K Spectrometer

Introduction:

Sharp 2K Spectrometer is a miniature spectrometer with a compact structural design and configurable spectral range. It boasts high resolution, with the optimal resolution reaching up to 0.07 nm; low stray light, approximately 0.1%; and minimal temperature drift, with a wavelength temperature drift of about 0.1 pixel/℃.

It is suitable for various industrial on-site measurement scenarios, including laser measurement, plasma emission spectroscopy measurement, color measurement, absorbance measurement, and Raman measurement. It is a cost-effective industrial-grade fiber optic spectrometer.

Features:

Stray Light ~0.1%;

With high resolution, up to a maximum of 0.07 nm;

Wavelength temperature drift ~0.1 pixel/℃;

Compatible with Venuslab pin-type multi-core densely arranged bundled optical fibers, with consistency of fiber insertion/extraction strength ≤ 7%;

Strong ultraviolet (UV) spectral response;

CCD quantized background noise ≤ 30 RMS (at minimum integration time);

Equipped with multiple communication interfaces including USB and serial port, a 24PIN interaction interface, and dedicated DAC and ADC, which enables enablement, intensity control and power feedback of matching light sources.

Specification data for the Sharp 2K Spectrometer

Notes:

CCD Readout Noise: At the minimum integration time, it refers to the root mean square (RMS) of CCD readout noise.

CCD Dynamic Range: At the minimum integration time, the dynamic range is calculated as (saturation value - dark noise baseline) divided by the standard deviation of CCD readout noise; the evaluation method refers to Oceanhood's enterprise standards.

(1) Interface Description

The figure below shows the various interfaces of the Sharp 2K Spectrometer. The optical fiber interface is an SMA905 interface, which is used to connect sampling accessories such as reflective probes, transmission-reflection holders, and liquid flow cells.

The Micro USB interface is used to connect to a computer via a data cable. The 2.0MM-24P interface (24-pin port) is used for the secondary development of the spectrometer.

(2) Wiring Pin Definition

The 24pin interface uses a 2.0MM-24P connector.
