FAQs

Gating is a feature of our intensifiers. It is a way of opening and closing the “gate” controlling the flow of electrons from the photocathode to the Micro Channel Plate of the image intensifier, similar to using a shutter in an optical system. Learn more about gating in VSI products in this White Paper.

Image Intensifier Assemblies, also known as Lens-coupled Image Intensifiers or Image Intensifier Lenses, attach to an existing camera similar to a lens to make an instant intensified camera for applications with low-light conditions.

VSI has a long history of developing image intensifier solutions. The use of image intensifiers in low light level imaging applications predates CCD and CMOS cameras. Since image intensifiers were developed for night vision, using them to image in the dark was a natural application. As with all optical components, integrating an image intensifier into the imaging chain alters the design parameters of the entire system.

Image intensifiers are often used for low-light conditions but also can enable video-rate or even single shot cameras to image fast events. The intensifier’s gate is used to shorten the shutter and can be set to nanoseconds, so even objects like moving bullets can be imaged without motion blur.

Alternately, an intensifier can be gated on multiple times within a single camera frame. The result is multiple exposures on a single camera frame. The fast burst of gate pulses reduces the effective inter-frame time. When the object travels across the frame, the resulting image can be used to measure trajectory and velocity.

VSI has been developing innovative imaging solutions since 1982. Our team of experts works directly with customers to provide expert advice and the highest quality built-to-order imaging products.

When you call VSI, you won’t be channeled through a Sales department. Instead you’ll speak directly to one of our engineers who can help you with every detail of your imaging solution, from design and development to production and reorders.

Our standard (off-the-shelf) products are listed on our website under Products. VSI custom products and services are too vast to list. Please contact us for details.

Please call our offices for current off-the-shelf pricing information. Our standard, off-the-shelf products are built to order and designed to be flexible. We can enhance the product to fit your specific application without a high price tag.

Yes, VSI does work with resellers to offer a limited scope of our products and services. Due to the specialized and often customized nature of our imaging products, we may require direct contact with the end-user, as coordinated with the reseller.

Yes, our team of engineers works in partnership with your team and resources to understand your unique challenges and desired outcomes and then to design and manufacture a product that meets those needs.

Our top priority is to meet the requirements of our customers’ specific applications. The mandate to match an existing spec deprives us of the discovery process to review the application with the user.

Although not alone in the imaging market, VSI offers a level of customization and consultation, particularly for one-off and low-volume orders, that is simply not available elsewhere.

VSI products are developed and manufactured in the Unites States and some are available for purchase internationally. Export regulations prevent us from discussing or providing some imaging technologies outside of the United States. Please call our offices to discuss your needs and we will be happy to advise which of our products, technologies and services are available for export.
