In recent years, ZWO has evolved from a supplier of astrophotography equipment into a major player in scientific and industrial imaging. With the ASI461, ASI990 and ASI992, the manufacturer is presenting three cameras that clearly go beyond the amateur sector and are aimed at research institutions, industrial partners and professional observatories.
ASI461 – Large-format scientific camera for maximum detail
The ASI461 is based on a large-area, highly sensitive sensor with extremely low readout noise.
Thanks to its wide dynamic range, the ASI461 delivers impressive image depth even with weak signals. For institutions that process large volumes of data, the camera is particularly attractive due to its high readout speed and robust electronics.
ASI990 – Professional SWIR camera for research and industry
With the ASI990, ZWO is entering the field of Short-Wave Infrared (SWIR) imaging. This camera is designed for applications that extend far beyond astronomy:The SWIR sensor provides insights into structures that remain hidden in visible light. The ASI990 combines high sensitivity with fast data transfer, making it ideal for real-time analysis.
ASI992 – Advanced SWIR technology for maximum precision
The ASI992 is the more powerful counterpart to the ASI990 and is aimed at users who demand the very highest standards in terms of:
Thanks to optimised cooling, improved noise performance and an extended dynamic range, the ASI992 is ideal for demanding laboratory environments, research projects and high-end industrial processes.
Applications for Astrophotography
Observation of objects with a strong redshift (e.g. very distant galaxies, provided you have the appropriate filters and optics)
Penetrating dust clouds – SWIR sees through interstellar dust better than visible light
Analysis of thermal signatures from instruments or mirrors
Laboratory astronomy (spectroscopy, materials testing, optical development)
Adaptive optics auxiliary camera (e.g. for IR guide stars)
