Midwest Optical Systems, Inc. offers lens filters for machine vision to cover nearly every type of lighting and subject. These are available in a variety of sizes and types such as shortpass, longpass, bandpass, polarizing, neutral density, IR and UV types
Machine vision filters from Midwest Optical Systems are designed to increase the contrast of the subject under inspection, improving the ability of the system to distinguish desired characteristics. Increased contrast allows for increased accuracy and speed. Some of the various filter types offered include Bandpass, Infrared, Neutral Density, and Polarizing – mounted and hard coated.
Over 66 different filter types are currently offered by Midwest Optical Systems, available in at least 16 sizes for each type. Please contact us if you need assistance with selecting a filter model and/or are interested in a swatch kit for testing purposes.
1) f = v x (D/V) or 2) f = h x (D/H)
f : focal length of lens
V : Vertical field of view
H : Horizontal field of view
D : Distance from Lens to Object
v : vertical multiplier (see table below)
h : horizontal multiplier (see table below)
|Camera Format||1.2" (Square)||1/1.8"||1/2.5"||CMOSIS CMV2000||CMOSIS CMV4000|
|Camera Format||4/3"||43.3mm||1/2.8" 1080p HD Sony IMX136||1/1.2" Sony IMX174||1/1.2" Sony IMX249|
|Camera Format||1/1.8" Sony IMX265||1/1.8" Sony IMX252||2/3" Sony IMX264||2/3" Sony IMX250||1/1.9" Sony IMX185|

Substitute these data to formula #1 above:
f = 4.8 x (2500/340) = approx. 35 mm
Therefore, specify a 35mm lens to achieve a 340mm vertical f.o.v. from 2500mm object distance with a 1/2" format camera.
Note: f.o.v. (V or H) and object distance (D) can be in any units of measure, provided they are both the same.
