NEW! MeVis-C Traffic 25mm f/1.6
Qioptiq now introduces a new version of the 25mm lens that is optimized for traffic applications
The MeVis lenses have been known to set the standard in imaging quality with c-mount cameras for many years. Qioptiq now introduces a new version of the 25mm lens that is optimized for traffic applications. The new MeVis-C Traffic 25mm f/1.6 features optimized color correction to minimize the focus shift between white light and near infrared.
In traffic surveillance, most often two different light sources are used:
Daylight with a maximum around 550nm
NIR flash at night with a maximum around 850nm
The diagram shows the focus shift of the MeVis-C Traffic 25mm f/1.6 lens in comparison to the standard version. The focus plane for green light and the NIR area are identical.
This optimization enables sharp images with both illumination scenarios. The traffic version also provides an adjustable aperture and focus ring which can be locked via set screws.
