SWIR Lens for QHY990

The QHY SWIR Lens designed for the QHY990/991 series enhances the camera’s capabilities for Short Wavelength Infrared (SWIR) imaging. Let’s explore the details:

1. Compatibility and Purpose:

   • The SWIR lens is specifically crafted for use with the QHY990 and QHY991 cameras.
   • It allows these cameras to capture images in the SWIR range, which typically spans wavelengths from 1200nm to 1800nm.
   • The lens facilitates imaging beyond the visible spectrum, making it suitable for scientific research, astronomy, and specialized applications.

2. Sample Image:

   • During daytime, a sample image was taken using the QHY990 with the 16mm F1.4 SWIR lens at F2.8.
   • The exposure time was 1.3 milliseconds, and the camera was set to a gain of 0.
   • The resulting image showcases the camera’s performance in the SWIR region¹.

3. Technical Specifications:

   • Lens Type: 16mm F1.4 SWIR lens
   • Spectral Range: 1200nm to 1800nm
   • Filter Compatibility: The lens can be used with appropriate filters within this wavelength range.
   • Application: Ideal for scientific imaging, infrared studies, and specialized astronomical observations.

In summary, the QHY SWIR Lens unlocks the potential of the QHY990/991 cameras for capturing detailed images in the SWIR spectrum, providing valuable insights beyond what the human eye can perceive
