What makes the QHY990 PRO II suitable for SWIR imaging?
The QHY990 PRO II uses a Sony InGaAs sensor with a broad spectral response from 400 nm to 1700 nm. This allows it to detect light in the short-wave infrared spectrum, where traditional silicon sensors are not sensitive. Its high quantum efficiency, peaking at 77% at 1200 nm, makes it ideal for scientific applications like spectroscopy, material analysis, and biological imaging.
How does the cooling system on the QHY990 PRO II work?
The QHY990 PRO II features a hybrid cooling system to combat the high dark current of its InGaAs sensor. You can operate it in two modes:
-
Air Cooling: Achieves a temperature delta of 35°C below ambient.
-
Liquid Cooling: Can reach 45°C below ambient with normal water, or up to 60°C to 80°C below ambient using a chilled liquid source for maximum noise reduction.
Can I use standard 1-inch lab filters with the QHY990 PRO II?
Yes. The camera includes an integrated filter holder designed for standard 25mm filters, which are equivalent to the common 1-inch filter size used in many laboratory and industrial applications. This allows for easy installation of bandpass, neutral density, or other analytical filters.
I need to integrate the QHY990 PRO II into an industrial inspection system. What are my connectivity options?
The QHY990 PRO II is equipped for high-throughput environments. It offers both dual 10 Gigabit Ethernet (10GbE) ports and a Camera Link interface. These connections provide the high-speed, reliable data transfer necessary for machine vision, quality control, and scientific data acquisition.
What is the advantage of the Cu-Cu interconnect technology in the QHY990 PRO II's sensor?
The sensor's Copper-to-Copper (Cu-Cu) interconnect technology is a modern fabrication method that creates a more direct and efficient connection within the pixel architecture. For the user, this translates to significantly lower Fixed Pattern Noise (FPN) and a reduced number of defect pixels, resulting in cleaner, more uniform images straight from the camera.
What is the optical interface of the QHY990 PRO II camera?
The QHY990 PRO II uses a standard C-mount optical interface. It has a back focus distance of 17.5mm, making it compatible with a wide range of C-mount lenses, microscopes, and other laboratory optical equipment.
