1. What do you need to know?
You will need to know the following basic parameters to
understand whether your optic and imager components will work with
the M3-F developer's kit:
- Mounting hole pattern
- Lens thread
- Lens dimensions
- Lens focal length for your imager size
- Lens travel required
- Imager array thickness (mounted) and diagonal dimension
- Lens viewing angle
2. Mounting requirements
The M3-F developer’s kit is designed with a base as shown in
Figure 1. Check the dimensions to ensure that no interferences to
components on your imaging board exist. Holes are compatible for
clearance of M1.4 or UNF 0-80 screw. If hole patterns are not
compatible, you will need to provide screw mounting holes or
adhesively mount the module onto the board surface.

3. Position of the lens relative to the image sensor
A typical image sensor array thickness can be 0.7 to 1.0 mm. You
need to establish the board-mounted
position of the top of your image sensor array, as well as its
diagonal image dimension (Figure 2). This information can be
provided by your image chip or camera board supplier. The infinite
focus position to the top surface of the sensor should establish the
lower position of the lens assembly for the lens you require.
4. Lens Specifications
The maximum travel of the M3-F module in the developer's kit is 1.5 mm. The upper and lower
range of this is a factory setting and established to avoid
over-travel of the lens barrel. The zero reference position places
the base of the adjustable M3-F barrel at 2.25 mm from mounting base
(Figure 2). This travel results in a fully extended travel limit of
the base of the barrel at 3.75 mm above the mounting base. Full
travel range for your optical system must be less than or equal to
1.5 mm.
The M3-F Module is provided with a 10.65 mm length threaded
barrel to allow insertion of M12X0.5 mm lenses. See Figure 2. Check
that the lens you wish to use is also an M12X0.5 mm lens. Smaller
lenses may be used, however an adapter will be required. An optional
M8X0.5 mm adapter is available for this kit.
Figure 2: M3-F Developer's Kit module dimensions
Additional basic information that you need from your lens
provider includes outer dimensions, infinite focus distance for the
imager sensor array geometry and viewing angle. With the lens placed
in a position of infinite focus, ensure that the field of view angle
does not intersect the M3-F housing (Figure 2). This will ensure
that clipping of your image will not occur.
For lenses that include a flange (Figure 3), interference with
the outer M3-F housing needs to be checked at this lowest lens
position as well.

array and lens combination, a cross-sectional dxf and pdf file of
the M3-F module are available for download
