Machine Vision Lenses

Multipix supply a large and varied selection of lensing from manufacturers such as, Ricoh (Pentax), Kowa, Moritex, HIKrobot, Computar and many more. With new lensing available for the latest CMOS sensor camera models. Our experts are trained in identifying the best lens type for your application.

Lens Calculation

A simple but very useful formula to calculate the focal length of a lens is shown below. This can be used to help determine the most suitable lens or range of lenses for a given application.Step1: What is the sensor size in your camera? (b)Step2: What is the optimum working distance? (WD)Step3: What is the size of the object being capture by the camera? (FOV)Look up the sensor size height (b) using the table below.


Lens filters are used to control/attenuate parts of the colour spectrum before they enter the lens/camera.All filters have a ‘roll-off’ characteristic that is usually available graphically.This describes how accurately the filter is eliminating or passing unwanted light.Multipix support an excellent range of filters from MidOpt. MidOpt filters with their unique ‘StablEDGE’ technology make them the number one choice – specifically designed to be less susceptible to effects from angular shifting seen when optical filters are placed in front of short focal length (<12mm) camera lenses.


Polarised light can be used to eliminate unwanted reflections, reduce glare from objects with smooth surfaces or surfaces covered with grease, oil or liquid.  Take a look at the options hereUsing a Polarised light can eliminate unwanted reflections. For example, in this video you will see all glare from this shiny foil lid is eliminated and the best before date can be seen with ease. Check out our video to see this effect in action!

To eradicate specular and reflective surfaces use two linar polarisers  – one for the light and the other for the lens. One of the polarisers is rotated until the unwanted reflection is eliminated!
