ASI992MM Pro SWIR

Description

The ZWO ASI992MM Pro SWIR is the higher-resolution sibling of the ASI990MM, built around Sony’s IMX992 InGaAs sensor. With 5.0 μm pixels in a larger 1920 x 1536 format, it offers roughly 2.3x more pixels than the IMX990, giving you a wider field of view and more detail across the sensor area — while maintaining the same short-wave infrared sensitivity from 400 nm to 1700 nm.

Like all InGaAs-based cameras, the ASI992MM Pro SWIR operates in a spectral range that silicon sensors simply cannot reach. This makes it invaluable for infrared planetary imaging, where longer wavelengths cut through atmospheric turbulence to reveal surface and atmospheric detail on Jupiter, Saturn, Mars, and Venus that remains hidden at visible wavelengths. Solar observers use SWIR cameras to study granulation and active regions with exceptional contrast.

The Pro designation includes regulated TEC cooling (critical for infrared work where uncooled sensor noise would dominate), USB 3.0 connectivity, and 256 MB onboard buffer memory for reliable high-speed capture. The camera is compatible with all major planetary capture software and integrates with the ASIAIR ecosystem.

The ASI992MM Pro SWIR represents the current state of the art in amateur infrared astronomy. Its larger sensor compared to the ASI990MM makes it the better choice if you want more field coverage for planetary imaging or if you plan to use it for research applications where resolution matters. This is a highly specialized instrument for experienced imagers who understand infrared techniques and want access to wavelengths beyond the reach of conventional cameras.
