  • SWIR Lens for QHY990/991

    This SWIR Lens for QHY990/991 is engineered to provide a high-transmission optical path specifically for the unique sensitivity range of Short-Wave Infrared sensors. It enables the full capabilities of cameras like the QHY990 and QHY991 by using specialized glass and coatings that are transparent to wavelengths where conventional optics fail, ensuring maximum signal reaches the sensor for scientific and industrial applications.

    Optimized Transmission for the SWIR Spectrum

    Standard camera lenses are designed for visible light; their glass and anti-reflection coatings absorb or reflect a significant portion of the SWIR spectrum. This lens is constructed with materials and multi-layer coatings specifically formulated to maximize throughput in the infrared, perfectly matching the operational waveband of QHY's SWIR sensors and preventing signal loss.

    Designed for the QHY990 and QHY991

    This is not a general-purpose lens adapted for infrared use. It is purpose-built to integrate seamlessly with the QHY990 and QHY991 cameras, ensuring both mechanical compatibility and optical alignment. This system-level design approach guarantees that the lens delivers a clean, well-corrected image to the sensor, making it a reliable tool for demanding imaging tasks like agricultural analysis, silicon wafer inspection, or counterfeit detection.

  • Why do I need a special SWIR lens for the QHY990/991 camera?

    Standard optical glass used in conventional lenses is often opaque to Short-Wave Infrared (SWIR) light. This dedicated SWIR lens uses specialized glass and coatings that are highly transmissive in the infrared spectrum, ensuring that the maximum amount of light reaches your QHY990 or QHY991 sensor for accurate measurements and high-contrast images.

    What applications benefit from using this SWIR lens with a QHY990 camera?

    This lens is ideal for a range of scientific and industrial applications where SWIR imaging provides unique data. Key uses include:

    • Agricultural Analysis: Assessing crop health and moisture content.
    • Industrial Inspection: Seeing through silicon wafers or detecting material defects invisible to the human eye.
    • Security & Surveillance: Imaging through haze, smoke, or fog.
    • Art & Document Analysis: Revealing underdrawings or alterations in historical artifacts.

    Is the SWIR Lens for QHY990/991 also corrected for the visible spectrum?

    This lens is optimized specifically for the SWIR band. While it may pass some visible light, its anti-reflection coatings and optical corrections are not designed for high-fidelity imaging in the visible spectrum. For best results, it should be used exclusively for its intended SWIR applications.

    What is the primary advantage of using this lens with a QHY990 or QHY991?

    The main advantage is system integration. This lens is designed to work as part of a complete solution with the QHY990 and QHY991 cameras, ensuring correct mechanical fit, focus, and optical performance without the need for third-party adapters or guesswork. It unlocks the full potential of the camera's SWIR sensor.

    Will this lens work with SWIR cameras other than the QHY990/991?

    While designed and optimized for the QHY990 and QHY991, it may be compatible with other SWIR cameras that share the same mechanical interface and sensor format. However, performance is only guaranteed with the specified QHY models. Users should verify compatibility before purchasing for use with other equipment.

    Can I use standard 1.25" or 2" astronomy filters with this SWIR lens?

    Compatibility with standard astronomy filters is not specified. Most astronomy filters are designed to block infrared light (IR-cut) or pass specific visible-light narrow bands, making them unsuitable for SWIR imaging. For SWIR applications, you would typically use specialized long-pass or band-pass filters designed for infrared wavelengths.
