Back-illuminated CMOS ultraviolet (UV) imaging cameras offer a cost-effective option for high-quality imaging in the 200-400nm range under moderately bright illumination conditions. The cameras shown here are based on two different image sensors:

IMX487, from Sony’s Pregius S family
Photonfocus UV

When used with UV lighting and UV-compatible lenses, these cameras can provide special visual information which visible light cameras cannot. These cameras operate in Global Shutter mode: all pixels begin and end exposure at the same instant. They are ideal for imaging fast changes or rapid motion in the Field-of-View.

The Ultraviolet spectrum of shorter wavelengths than those of visible light. Imaging in the 200-400nm is useful for many specialized applications, including the detection of minute scratches and other defects that are undetectable in visible light. These cameras are well suited for applications such as sorting materials because they can image materials such as glass, plastic and PET which are transparent in the Visible region, but have different absorption rates in the UV region of the spectrum.

In addition to the 200-400nm UV region, these cameras have sensitivity in the Visible and NIR regions as well, which permits their use in broadband and multispectral imaging applications.

Use your mouse to read QE data at wavelengths of interest.
Right-click and drag to zoom-in along the X-axis to expand the view for a desired range of wavelength.
To pan left or right within a zoomed-in view, hold down the Shift key and use your mouse.
To revert from a zoomed-in view to a normal view, click on the “Reset zoom” button that is displayed at the top-RHS of the graph.

All QE values on this website are the best estimates available from various sources, and not necessarily from the manufacturer of the specific image sensor or from the manufacturer of the cameras in our Product Showcase. They represent the best estimates for the imagers by themselves, with the caveat that glass and other optics in the imaging path can significantly impact the spectral sensitivity of an imaging system.

As described on our Knowledge Base article on this subject, these values exist in a range. Therefore no absolute precision is implied, even when QE values are shown to two decimal places! These values and graphs are intended to be used for reference can be use for making useful comparisons between cameras. They are not intended to be a specification or a performance guarantee.

In applications that require the best achievable optical resolution, it is desirable to use a lens with an optical resolution ≥ 182.5 lp/mm for an image sensor with a pixel size of 2.74μm. This will ensure that the optical resolution of the camera & lens combination is Nyquist-limited by the pixel-size of the camera, and not by the quality of the lens.

In applications that require the best achievable optical resolution, it is desirable to use a lens with an optical resolution ≥ 67.6 lp/mm for an image sensor with a pixel size of 7.4µm. This will ensure that the optical resolution of the camera & lens combination is Nyquist-limited by the pixel-size of the camera, and not by the quality of the lens.
