Day and Night Vari-Focal Technology
Honeywell offers a real solution to day and night surveillance applications with its line-up of DC auto iris Vari-Focal lenses that deliver clear, sharp, color images in daylight and black and white images in darkness using near infrared illumination, without the need to refocus the lens. Our lenses achieve day/night lighting corrections through a combination of our proprietary optical design and aspherical elements, allowing superior wide aperture performance (F0.95) in low light to capture high quality images even in horizontal field angles up to 94 degrees.
Today’s lens market is rapidly changing from part-time observation (day or night) to round-the-clock surveillance. With Honeywell Day/Night Vari-Focal technology, you now have the ability to upgrade or integrate CCTV security systems affordably. The ability to view high contrast, clear, detailed images adds value to any project. Advanced aspherical design engineering reduces distortion and provides accurate visual identification of subjects in daylight, low light and near infrared light, without the need to refocus the lens. In addition to extraordinary low-light functionality, Honeywell Day/Night lenses are compact, light-weight and easy to install making them perfect for use with true day night cameras in outdoor installations such as parking lots, ports and other areas where low light imaging is important.
Ability to see a high contrast, clear, and detailed picture of the subject in daylight, low light and near infrared light, allowing identification of a subject rather than just observation.
Honeywell’s HLD29V8DNL (2.9 – 8mm, F0.95), HLD27V13DNL (2.7 – 13mm, F1.3) and HLD5V50DNL (5 – 50mm, F1.6) day/night lenses provide the widest maximum aperture for their focal range, which leads to better low-light performance of the camera. All lenses use aspheric lens elements, which are curved so that each light ray focuses on the same point of the focal plane, reducing the number of lens elements and therefore reducing the optical distortion in the image. The lenses are small, compact and lightweight.
The HLD29V8DNL and HLD27V13DNL are the only day/night lenses on the market with focus-tightening knobs separate from the focusing ring. This provides easier installation and ensures that any tightening of the focusing knob will not accidentally shift the position of the focusing ring. Both lenses have the widest zoom range, largest maximum aperture, and smallest size and weight in their class.
The day/night lenses have a unique optical design that enables them to provide crisp color images in daylight and black and white images in darkness using nearinfrared illumination, without the need to refocus the lens. They are ideal for use with true day night cameras in outdoor installations such as parking lots, ports and other areas where low-light imaging is important.
