Transmission-imaging fiber optic spectrometer ST90S
Jianzhi Technology's high-throughput transmission fiber spectrometers use VPH volume-phase holographic gratings with diffraction efficiency approaching 90%. Combined with high-quality imaging optics, sensitivity can reach 5 times that of reflective spectrometers and limiting resolution can exceed that of conventional spectrometers by 2 times. A research-grade deeply cooled area-array CCD camera provides very high quantum efficiency and signal-to-noise ratio. High stability and compact size support industrial integration. ST50S can replace and outperform conventional research InGaAs spectrometers and is recommended for highly sensitive 1064nm Raman systems. ST90S supports 532nm laser Raman spectroscopy, particularly gas Raman detection, with excellent overall optical performance, spectral coverage up to 4200cm⁻¹ and resolution down to 4cm⁻¹, replacing large imported research reflective spectrometers. ST100S integrates into research-grade 785nm Raman systems for materials and biological samples, with resolution down to 3cm⁻¹.

As a core precision optical component for wavelength screening, frequency locking and spectral demodulation, optical etalons are widely used in high-end scientific research and precision laser equipment.
As a vital emerging sector of modern three-dimensional spatial economy, the low-altitude economy has become a new global growth driver. It covers a wide range of commercial scenarios, including UAV navigation and obstacle avoidance, precise airspace management, aerial mapping, low-altitude logistics distribution, security monitoring and emergency disaster rescue. Nevertheless, frequent extreme weather, complex terrain obstacles and increasingly dense low-altitude flight activities pose severe challenges to the safety and stability of low-altitude aircraft operations.
Laser pump sources are the core energy input component of solid-state lasers and laser amplifiers, and their performance directly determines the output power, beam quality and service life of the entire laser system. In scenarios such as industrial processing, scientific research experiments and high-end equipment, improper pump source selection will not only result in substandard system performance, but also bring a series of problems such as rapid device degradation and high operation and maintenance costs. This article sorts out the core selection logic and key pitfalls of pump source procurement, and provides selection references based on mature, mass-produced high-reliability products to help purchasers efficiently screen suitable products.
