Low Light Night Vision Camera

L3Vision Cameras & Sensors

L3 Camera (also known as electron multiplication CCD or EMCCD) is an advanced CCD technology that offers performance in excess of the best intensified CCDs. L3Vision™ finds its main areas of application in photon-starved situations such as night-time surveillance, astronomy or the detection of fluorescent and luminescent markers in life sciences. Its ability to operate across the full range of light levels brings a huge increase in system flexibility. In life sciences, fast, high sensitivity operation can be combined with quantitative, slow-scan and time integrated imaging measurements. For surveillance, true 24-hour capability is now possible in one sensor.

Cameras

L3Vision™ cameras provide optimised solutions for the most demanding imaging applications.

L3 C95 Series

INTRODUCTION

The L3C95 Series offers all the benefits of the L3Vision technology, with a range of features that enhances performance at very high and very low light levels. This range of cameras utilises high performance DSP to extend operation beyond overcast starlight, whilst the high resolution CCD sensor provides even sharper images for illumination levels at or above moonlight.

FEATURES

· 768 pixels per line
· Extended integration capability
· Selectable filters for enhanced image quality at low light levels
· Genlock to external video source
· Intelligent power management
· Remote control of camera performance
· Analogue and digital outputs
· Fully automatic operation over 9 decades of illumination
(with T350 auto-iris lens)
· Operation from DC supply in the range 10 to 16 V
· Immune to overexposure

APPLICATIONS

· Night-time surveillance

· Scientific Imaging

· Biomedical Imaging

L3 C216 Series
Compact Low Light CCD Imaging System

INTRODUCTION

The 216 series provides all the benefits of the existing
L3VisionTM range in a smaller package, and demands less
power. The 2/3” format sensor allows use with smaller
optical components, further reducing system payload. Since
the sensor is back-thinned, performance is similar to that
obtained with e2v's existing 1” format sensors. An improved
CCD manufacturing process reduces horizontal smear.

FEATURES

• 2/3” image format

• Back-thinned CCD for high sensitivity

• Enhanced blue response

• 768 pixels/line

• Automatic image enhancement

• Fully automatic operation over 9 decades of illumination

with a F.14 T350 Auto-iris lens

• Analogue and Camera Link-compatible digital outputs

• On screen display for manual control/monitoring

• 12 V DC supply (see note 1)

• Fan-less cooling

APPLICATIONS

• Airborne surveillance

• Ground-based surveillance

• Underwater imaging (enhanced blue response)

• Driver view enhancement

• Commander's night-sight

• Scientific imaging

Sensors

Patented sensors offer a new capability in low light imaging. The image signal is amplified on the chip while it is still in the charge domain. This allows the sensor to operate in real time with sub-electron equivalent readout noise, enabling very dim sources and very dark scenes to be imaged. These sensors are available with shielded anti-blooming, which maintains full well capacity and high quantum efficiency whilst minimising blooming from strong light sources in the object being imaged.
