1.3 Technical Specifications
1.3.1 Lens Options
MOBOTIX offers the M25M with
lenses in three different 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
seven different MOBOTIX lenses
are offered:
• L23 Super Wide-Angle with 92° angle of view (horizontally)
• L25 Super Wide-Angle with 82° angle of view (horizontally)
• L38 Wide-Angle with 55° angle of view (horizontally)
• L51 Wide-Angle with 40° angle of view (horizontally)
• L76 Tele with 27° angle of view (horizontally)
• L160 Tele with 13° angle of view (horizontally)
• L320 Tele with 7° angle of view (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 angle of view 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 cam-
era 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
L27–60 1/2” Vario lens
(58° to 28° horiz. angle of view)
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.
