ZWO ASI990MM-P – 2.1MP Professional NIR/SWIR Astronomy Camera with InGaAs Sensor

The ZWO ASI990MM-P is a professional monochrome astronomy camera designed for near and short-wave infrared imaging (NIR/SWIR 2.2–1.7 μm). Thanks to its high-end InGaAs sensor and extremely low noise, it is ideal for scientific observations, advanced photometry, and specialized low-light imaging.

Main Features

• 2.1 MP InGaAs sensor with high sensitivity for NIR/SWIR imaging.
• Extended 2.2–1.7 μm spectrum optimized for scientific observations.
• Extremely low read noise for greater photometric precision.
• Dual-stage TEC cooling for long exposures and thermal stability.
• High frame rate for research applications and fast imaging.
• High-speed USB 3.0 for fast and reliable data transfer.
• ST4 port for integrated autoguiding.
• Compatible with professional software (ASIAIR, SharpCap, NINA, etc.).

Exceptional Optical Performance

Thanks to InGaAs technology, the ASI990MM-P offers unparalleled sensitivity in the near and short-wave infrared, ensuring detailed output even under extremely low-light conditions. Low noise and 14-bit depth allow for clean, high-dynamic-range captures.

Dual-Stage TEC Cooling

The integrated TEC cooling system keeps the sensor at a stable temperature, significantly lower than the ambient environment, effectively reducing thermal noise during long exposures and improving the quality of scientific images.

Robust and Compact Design

The aluminum alloy body ensures lightness and durability. The construction is optimized for long observational sessions, with efficient heat dissipation and stable connectivity even in challenging conditions.
