Lens calculator edmund Please note that performance will vary based on source and lens selections. 8". They are a leading global manufacturer and supplier of high quality imaging lenses for machine vision. For instance, if you know the “Working Distance” and “Focal Length” of your lens, select the “Field of View” option in Step 1 and complete the required fields and then Relate optical and mechanical parameters of simple lenses in order to ease integration into application assemblies. Determine the illuminated spot size resulting from a collimated light source passing through a singlet based on the input beam diameter, the lens focal length, and the propagation distance. I have never made a lens and am having problems understanding how to calculate the sagitta of R1 and R2. PLEASE NOTE, as a result of the recently imposed global tariffs, we are seeing rapid and unforeseen price increases from manufacturers. The effective numerical aperture of the application can only be calculated if the user knows the beam diameter. Depth of field calculator: This tool will calculate the depth of field and hyper-focal distance for a given lens focal length and f/# . It is also important to keep in mind that there are many additional factors involved, and this limitation is often much lower than what can be easily Need help choosing a lens?
