Ikegami IK-12VM412ASIR overview

  • 1Description

Note the "IR" designation in the lens' model number. This means that the optics in this lens were specially formulated to process light waves in the infrared spectrum. This makes the Ikegami IK-12VM412ASIR (by Tamron) a wise choice for use with Day/Night cameras or with B/W CCTV cameras sensitive to near infrared light.

IR Corrected
An IR corrected lens is a must for a Day/Night camera. With a regular lens, the image will most likely become blurred in Night mode and you will have to manually adjust the camera's focus in order to get a clear picture, only to see it go blurry again when the sun rises. This is due to the difference in the wave properties for visible light and for light in the infrared spectrum.
Aspherical Lens
An aspherical lens elements design plays an important role in keeping images sharp, especially around the edges of the lens. The advantages of this will become apparent whether the lens is used with conventional or digital CCTV cameras.
Ring Lock Mechanism
A ring lock mechanism allows the control rings on the lens to be secured into place to prevent them from shifting once they've been set.
Environmentally Conscious Design
Special consideration went into the manufacturing of this lens to keep it environmentally friendly. These include the use of lead-free glass elements and lead-free soldering methods.
