Compact size, high-sensitivity linear array sensor, covering ultraviolet-visible, near infrared range (200~ 1000 nm), supports USB connectivity, easy for industrial integration and control.
JINSP multi-purpose compact fiber optic spectrometer is characterized by small size, high performance, cost-effective, and versatility. It is well suited for building various common spectral measurement systems, enabling reflection, transmission, and absorption spectra in the range of 200 to 1100 nm.
The spectrometer employs the industry's highest-quality diffraction blazed grating and excellent optical design to ensure high optical luminous flux (throughput) and improve weak signal detection capabilities. Replacing diffraction gratings with different line densities, high- resolution spectral detection can be achieved in the ultraviolet, visible, and near-infrared bands. Equipped with a 2048-pixel high quantum efficiency CMOS chip and a professional high-speed, low-noise signal acquisition and processing circuit, it delivers optimal spectral signal-to-noise ratio.
The internal integrated temperature sensor can monitor the ambient temperature in real-time. Combined with the internal temperature drift compensation algorithm, it can achieve the smallest temperature drift within the operating temperature range.
Specifically, the SR50C adopts a crossed C-T optical path, providing high sensitivity. The SR75C utilizes a 75mm long focal length reflective mirror coupled with M-type C-T optical design, ensuring optimal optical aberration and resolution. The SR50D features a crossed C-T optical path and an internally integrated semiconductor cooling chip, allowing the chip to operate at 5°C (adjustable temperature) to enhance signal stability.
