Lens Angle-Does anybody understand this term

Hi
I was looking at optic lenses for a cree type LED. Can anybody tell me what this means

Lens Angle: 4-90 Degree

Does this mean this lens have a 43 degree (=90-4/2) dispersion off the center axis?

Thanks

Yes, that's correct. Angle is off the centerline.
