1.3 Technical Specifications
1.3.1 Lens Options
MOBOTIX oers the M25M with lenses in three dierent classes of focal length. Since
MOBOTIX cameras are backlight-proof, none of these lenses requires a mechanical auto
iris, thus making the camera extremely robust and maintenance-free. MOBOTIX lenses
deliver good image quality even when using maximum digital zoom.
M25M with Standard Lenses and M14 Thread
A total of five dierent MOBOTIX lenses are oered:
• L25 Super Wide-Angle with 82° image angle (horizontally)
• L38 Wide-Angle with 55° image angle (horizontally)
• L51 Wide-Angle with 40° image angle (horizontally)
• L76 Tele with 27° image angle (horizontally)
• L160 Tele with 13° image angle (horizontally)
• L320 Tele with 7° image angle (horizontally)
The standard lenses can be exchanged at any time without having to dismantle the
camera. The camera is shipped either with a color day sensor or a light-sensitive black
and white sensor for low lighting conditions (Day or Night variants).
M25M with Hemispheric Lens L12 (Fisheye)
The hemispheric M25M model (M25M-Sec-D12) is only shipped with one L12 Fisheye lens
with a horizontal image angle of 180° and 5 megapixel color sensor. The lens distortion
that is specific to each lens is corrected in the live image by the MOBOTIX camera software.
Due to the special outdoor-optimized design of the camera, the full sensor image cannot
be used with all available image display options (parts of the weatherproof housing may
be visible in the image). This model only allows using L12 lenses; other lenses cannot
be used with this variant.
M25M with CSVario Lens
The M25M-Sec-CSVario is shipped with a CS mount, a compact L29–L64 1/2” Vario lens
(58° bis 28° horiz. image angle) and an optional color or black and white sensor (Day/
Night). In addition, commercial CS and C mount lenses (C mount lenses with adapter
ring) with a diameter of up 36mm and a length of up to 43mm that are designed for
megapixel image sensors (1/2.5“ and larger) can be used. Using other lenses will produce
shadows at the image borders and will reduce image sharpness.
